Reducing feed costs with
acidifier
Acidifiers help lower FCR while maintaining
high animal performance as a solution to
rising ingredient costs
Nataliya Roth
F
eed prices have jumped to a record high and further
increase is on the horizon. On the one hand there are
diminishing supplies, mainly due to poor crops in
many producing countries and on the other increasing
demand due to corn use for food and feed industries and
bioethanol production. The discrepancy between supply and demand is not expected to
lessen in the near future.
Livestock producers were already facing heavy losses due to the high cost of production,
making it near impossible to pass on the additional increased feed costs to farmers. One
possible solution is to reduce feed consumption but to keep animal performance at an optimum.
Feed conversion ratio is one of the main factors delivering profitability: improving
FCR leads to cost savings.
The benefit of acidifiers in poultry production is demonstrated by the following calculation.
Data is based on a 5% FCR improvement, which is the average benefit of worldwide use of
Biotronic acidifier from Biomin, Austria.
All parameters are constant, except the FCR, which has an influence on feed intake and
therefore on feed savings. For the clear view further benefits of acidifiers were not considered
in the calculation.

FEED ADDITIVES
As shown in Table 1, total feed intake of broilers in the trial group with acidifier was decreased
by 1.854 kg, because of reduced FCR from 1.80 to 1.71.
Feed prices differ depending on the country, but an increase in price is worldwide. Table 2
shows the difference in cost savings due to reduced feed intake at two price levels. The
two price levels are the market prices of feed for poultry in December 2006 and December
2007.

In both cost regimens, the inclusion of acidifier reduced the total feed cost per 10,000
birds. It is evident that, as the feed cost increases, the benefit of acidifier increases markedly
(Figure 2). It can be seen in the example that feed costs increased by 36% but cost
savings due to incorporation of acidifier increased by 214%.

FEED ADDITIVES
As mentioned, feed costs vary depending on the country and there will be further price
increases. Therefore one more example (Figure 3), shows the influence of different feed
cost levels on cost savings. Data for calculations were the same as shown in the example
above (10 000 broilers, FCR improved from 1.8 to 1.71)
Figure 3: Influence of feed cost increase on cost savings
Conclusion
Acidifiers markedly improve FCR and therefore help farmers to save money.
Feed cost calculations incorporating FCR optimization due to feed supplementation with
acidifier highlights this effect.
The noticeable outcome of this calculation is a profit difference between higher and lower
feed cost. The multiple effects of cost savings were observed. This means the higher the
feed costs, the greater the benefit that can be gained by the use of acidifiers.

A sustainable alternative to antibiotic
growth promoters in poultry nutrition
Galibiotic is a specific fatty acid mixture that has been shown
to stabilize the microflora and prevent the development of
pathogenic bacteria when added to poultry diets; it has a
positive effect on the intestinal health and on the overall health
status of the chicken.
Katrien Deschepper and Joost Ameye
T
he ban in the EU on the use of all
antibiotic growth promoters (AGP)
in animal feeds results in important
challenges for the European poultry
producers as far as the regulation of the
intestinal gut flora is concerned.
Poultry performance and feed efficiency are
closely interrelated with the quantitative and
qualitative microbial load of the host animal,
including the load in the alimentary tract and
in the environment. The most important effect
of AGP is the stabilization of the intestinal
microflora resulting in less problems with
necrotic enteritis caused by Clostridium
perfringens.
In order to be a valuable alternative to growth
promoting antibiotics, the proposed product
must show a similar mode of action.
MODE OF ACTION
The antibacterial effect of the product is based
on the following principles:
• Disruption of the structure of the bacterial
cell membrane. The specific fatty acids with
their amphoteric character can lodge in the cell membrane of the bacterium and thus
change its permeability so that the bacterial cell leaks and dies.
• The active ingredients of Galibiotic in their undissociated form can penetrate through
the bacterial cell membrane and then lower the pH of the cell content so that the bacterial
cell dies.
• The active ingredients of Galibiotic prevent the adhesion of bacteria to the intestinal
wall. The consequence is that bacteria cannot colonize and are washed out. This is most
probably induced by inhibition of the lipolytic activity (enzyme production) of bacteria
(Grippa et al., 1999).
• FEED TECHNOLOGY UPDATE — MAY/JUNE 2008 •

POULTRY HEALTH
ANTIBACTERIAL EFFECT
Galibiotic has been specially developed to control the intestinal microflora of poultry.
It has been shown that the antibacterial effect of it is 5 to 10 times higher compared to
traditionally used short chain fatty acids against both Gram-positive and Gram-negative
bacteria. As a result, Galibiotic is able to stabilize the microflora and avoids the development
of pathogenic bacteria such as Clostridium perfringens, E. coli, Salmonella…
SALMONELLA CONTROL WITH GALIBIOTIC IN POULTRY
Short chain fatty acids (formic, acetic, propionic and butyric acid) are commonly used in
the poultry industry to control Salmonella. Although fecal shedding of Salmonella can be
decreased, short chain fatty acids have undesirable effects. The acid resistance of Salmonella
typhimurium was enhanced upon exposure to short chain fatty acids.
On the other hand, feed supplementation with acetic and formic acid results in an increased
colonization by Salmonella enteritidis of caeca and internal organs compared with
birds receiving non-supplemented feed (Van Immerseel, 2004). This means that care
should be taken when short chain fatty acids are used to control Salmonella in poultry.
After short chain fatty acid exposure, it seems that Salmonella bacteria are driven to intracellular
compartments of the intestine. In this case bacteriological examination of the
cloacal swabs and litter samples could be negatively while the animals are carrying the

bacteria inside their organs. It is known that carrier animals can excrete the bacteria intermittently
under certain stress conditions and can contaminate unexpectedly the other birds
in the flock (Ducatelle et al., 2000).
Galibiotic was used to evaluate its efficacy for reducing the abundance of Salmonella
enteritidis in the intestinal tract and in some internal organs in young chickens.
The trial was performed by Dr. ir. Filip Van Immerseel of the University of Ghent, Faculty
of Veterinary Medicine.
The use of Galibiotic decreased the excretion of Salmonella enteritidis as measured in the
cloacal swabs. Even more interesting was the lowered number of Salmonella enteritidis in
the intestinal organs after supplementation with Galibiotic. This means that Galibiotic decreases
the invasion. These invasion-decreasing properties are serotype independent
(Van Immerseel, 2004). Based on these data, Galibiotic was used by a Dutch feed producer
to solve the problem of Salmonella. Four farms suffering from Salmonella (java and
typhimurium) during several cycles included Galibiotic in the broiler feed.
The growth promoter avilamycine was replaced by Galibiotic. Salmonella was determined
using the overshoe method and by bacterial counts of caecum content. Besides this, technical
data were collected and compared with the technical performances of two previous
cycles on the same farm, with a growth promoter added to the feed.
The technical performances are summarized in Table 1. It was clearly demonstrated that
Galibiotic has a positive effect on daily weight gain and feed conversion ratio and resulted
in a lower mortality.
The use of Galibiotic during two cycles resulted in a complete eradication of Salmonella.
During the first cycle, Galibiotic lowered the infection pressure. This continued during the
second and third cycle, resulting in Salmonella-free flocks. It is clear that the success of
Salmonella control programs does not solely depend on the use of a single measure.

The more ‘hurdles’
incorporated to reduce
the spread of Salmonella,
the more success
may be expected.
Adding Galibiotic offers
poultry farmers an
opportunity to build an
extra hurdle against
Salmonella, and it
seems it is the ultimate
‘hurdle’ Salmonella
stumbles over.

CONTROL WITH
GALIBIOTIC IN

(LANCKRIET ET AL.,
2007)
The effect of Galibiotic
on Clostridium was investigated
by means of
a challenge model. On days 19 till 22 all individual broilers were orally inoculated with
Clostridium perfringens type A, in combination with Paracox 8 vaccination on day 20. Paracox
8 vaccination as well as the addition of 30% fishmeal in the diet were used as predisposing
factors to induce necrotic enteritis. Lesion scores for necrotic enteritis were determined
on days 22 till 26.
Following treatments were applied: (1) control diet, (2) control diet with Galibiotic at 1 kg/
tonne of feed.
From this trial it was concluded that the percentage of animals with a positive lesion was
significantly reduced with 45 % by the addition of Galibiotic.

“It is known that carrier animals can excrete the bacteria intermittently

birds in the flock “
EFFECT OF GALIBIOTIC ON INTESTINAL HEALTH
The effect of Galibiotic on villus length (V), crypt depth (C), and V/C is shown in Table 2,
on the previous page. The height of the villi is related to the absorption capacity of nutrients
by the enterocytes. The higher the villi, the better the absorptive capacity of the small
intestine.
The crypts of Lieberkühn are responsible for the formation of new enterocytes. Migration of
enterocytes to the top is in balance with loss of enterocytes at the top due to apoptosis
and damage. When an important loss of enterocytes due to the presence of important
numbers of pathogenical bacteria occurs, the crypts will show an increased depth (personal
communication Decuypere, J.). Also Sakata (1987) demonstrated that an increase in bacterial
activity in the gastro-instestinal tract was associated with a change in the morphology
of the gut wall.
It has been demonstrated that the addition of Galibiotic to the poultry feed results in
higher villi, and increased V/C. The higher V/C for Galibiotic supplemented feeds is indicative
for a lower turnover rate of the intestinal mucosa. It is indeed generally accepted that
an increased villus length, in combination with lower crypt depths causes a lower migration
of enterocytes along the villi and decreases enterocyte loss from the villi. This results in
improved digestive and absorptive capacities of the small intestine.
EFFECT OF GALIBIOTIC ON TECHNICAL PERFORMANCES OF POULTRY
Trials at numerous research institutes have shown that the addition of Galibiotic to the
feed has a positive effect on body weight and feed intake.
Technical performances collected from customers worldwide consistently show higher body
weights of the chicks, lower mortalities and better FCR (table 3). From field trials it is also
concluded that the addition of Galibiotic results in dry litter, reduced use of antibiotics, important
reduction in case of IBD or Mg passage, eradication of Salmonella and a reduced
mortality due to colibacillosis.
EFFECT OF GALIBIOTIC ON THE PERSISTENCY OF LAYING HENS
In a trial with laying hens from 45 to 55 weeks of age it has been demonstrated that Galibiotic
has a significant beneficial effect on daily egg mass and on feed conversion
Huyghebaert et al., 2007).
This trial showed that at high performance, Galibiotic is a very promising tool for laying
hens. It is suggested that the efficacy of Galibiotic is even more important at lower laying
performance (e.g. with advancing age of the flock) and/or imbalances of microbial-related
physiology of the gastro-intestinal tract.

CONCLUSION
The addition of Galibiotic to poultry diets results in a stabilization of the microflora and
prevents the development of pathogenic bacteria such as Clostridium perfringens and
E.coli. Furthermore, it has been clearly demonstrated that Galibiotic has a positive effect
on the intestinal health and on the overall health status of the chicken and allows the
control of Salmonella. Therefore, it can be concluded that Galibiotic is a sustainable alternative
of antibiotic growth promoters in poultry diets.

on a Buhler premix system
A
lmarai is the
world’s largest
integrated dairy
group. Set up in
1976 by Prince Sultan
bin Mohammed bin Saud
Al Kabeer, the Saudi
enterprise expanded at a
breathtaking pace.
Whereas sales revenues
had amounted to 2.8
billion Saudi riyals in
2006, the corporate
headquarters in Riyadh
has budgeted a turnover
of 3.8 billion SAR or
some US$1 billion for
the current year.
86,000 HEAD OF CATTLE, 140 PRODUCTS
The cattle farms of Almarai are all located in the midst of the Saudi Arabian desert in a
corridor between the cities of Al Kharj and Harrad some 150 kilometers southeast of the
capital Riyadh.
The various farms accommodate a total of 50,500 dairy cows and 35,500 heifers of the
German Holstein race. The 86,000 animals are kept in fully automated and air-conditioned
barns.
They are cared for around the clock by specialists and monitored by veterinarians. In all,
Almarai employs over 8,000 people.
Milking is also done fully automatically and under extremely hygienic conditions. Each of
the 86,000 cows is milked four times a day on the various farms. The Almarai milk cows
achieve a very high level of productivity under these highly mechanized conditions, producing
an average of 12,400 liters of milk annually.
The group’s production facilities process these enormous volumes of milk into over 140
different dairy products. The company’s fleet of 1000 trucks supply them daily to some
34,000 stores in the countries of the GCC region (Arabian Gulf Cooperation Council) out of
numerous distribution centers.
Almarai is the acknowledged market leader in the Arabian Peninsula, holding a market
share of about 50% in fresh milk.

CASEBOOK
The new premix plant allows the establishment of a
TQM system, fully integrates all the processing
operations, ensures fast response times and
minimizes inventory levels
FEED PRODUCED IN-HOUSE
The Almarai Group manufactures its own feeds for its 86,000 animals. They are based on
corn (maize) flakes, which Almarai also produces in-house on two large flaking systems. To
this are added hay from locally grown alfalfa, oilseed extraction meal, molasses, and a premix
made up of various minerals and additives.
Since March 2007, these highly enriched feed additives have been manufactured on a
state-of-the-art premix system supplied by Buhler.
Jürg Solenthaler, area manager of the Buhler
Feed & Oil business unit, has fond memories of
the contract awarded by Almarai to construct
the large-scale plant in the middle of the desert
close to Al Kharj.
“Initial contacts took place in 2002. We were
awarded the final order in September 2005. One
year later, we started with the installation work.
In January 2007, we started up the entire
installation and began training the staff.
In March 2007, the plant was handed over to
Ramakrishna Setty K.T., which is in charge of
premix production at Almarai.”
EIGHT METRIC TONS PER HOUR
The new premix plant operated by Almarai is a
fully automated installation that was completely
supplied by Buhler. Every hour, it allows eight
tonnes of feed additives to be blended. The
plant consists of the raw materials receiving
(intake) section, a large number of storage bins
for holding the up to 30 ingredients of the
Almarai premixes, the grinding line for preparing
the carrier substance, the blending and mixing
unit as the heart of the premix system, and the
bagging and packaging section including a
palletizing line. The complete plant is computercontrolled
and housed in a 32-meter-tall steel
structure built by the customer.
The micro-dosing unit allows computercontrolled
admixing of extremely small
quantities
• FEED TECHNOLOGY UPDATE — MAY/JUNE 2008 •

CASEBOOK
This high-tech plant manufactures the “mineral tablets in a powdered form” for the bovines
in one-ton batches, explains Jürg Solenthaler.
“The plant must be permanently up and running, since fresh premixes are produced every
day.”
CUSTOMER VALUE
Depending on the specific formulation, up to 30 ingredients are fully automatically blended.
“Our system is capable of automatically blending even the tiniest quantities,” explains Jürg
Solenthaler.
“On the one hand, this allows permanent product retracing, and on the other hand it enables
the guaranteed accuracy to be achieved.”
For its premix plants, Buhler guarantees a mixing accuracy with a variation coefficient (CV)
better than 5%.
Now that the new premix plant has gone into service, Almarai can shut down its former,
manually operated installation near Riyadh, which had ceased to satisfy the capacity and
quality requirements. In addition, the relocation of premix production to the farms slashes
transportation costs. Last, not least, the increased capacities allow Almarai to gain independence
of third-company supplies.
Beside ensuring an improved premix quality level, the new premix plant also makes organization
easier for Almarai. It allows the establishment of a Total Quality Management
(TQM) system, unites all the processing operations at a given local site underneath a single
roof through full integration, ensures fast response times, and minimizes inventory levels.

Bolt ‘n’ Go chain and flight system
The Bolt ‘n’ Go system is all about making life easier for the end
user: ease of use, inexpensive and above all low maintenance
and down time.
By Dave Wolstencroft
T
he Bolt ’n’ Go chain and flight
system is a revolutionary
assembly method for drop
forged and round link conveyor
chain systems. The link and
flight assembly is made easier by
attaching the flight to the chain link
using a standard bolt and nut, with a
high case hardness and high tensile
hollow pin.
Traditional chain systems have used
pins and circlips. The problem with
this system is that during any maintenance
repairs on the chain, the
whole chain would have to be lifted
out of the conveyor to conduct repairs.
This results in large down time
in production and high maintenance
costs. With the Bolt ‘n’ Go system, to
conduct repairs such as to change
flights or pins can be done inside the
conveyor, without even taking the
tension out of the chain. Instead of Traditional pin and circlips arrangement with welded flight
welded flights, we are using bolt on
flights, and again these can easily be changed without any fuss.
Another problem with traditional systems using pins and circlips, is that circlips can come
off in some circumstances, causing the chain to become disconnected, and again downtime.
With the bolt n go system, the pins, chain and flights are secured using a secured
lock nut, which securely holds the system together in a consistent manner, but also facilitating
easy and safe removal when required.

several commodities, including wheat and
soybeans, at the rate of around 70,000,000
bushels per annum.
They have several drag conveyors which use
drop forged chain, with the traditional pin
and circlip assembly. While this has proved a
reliable assemble method for them, it has
proved time consuming when changing out
bent or broken chain flights.
Bill Hoffer, Head of Maintenance said of the
system “We installed 4B’s new Bolt ‘n’ Go
chain, and I am pleased with the results.
The Bolt ‘n’ Go chain is very easy and fast to
install and maintain, as you eliminate the
need to separate the chain each time while
installing a new flight. Also there is no need
Bolt ‘n’ Go chain system installed and running
successfully at CHS
to slacken off the chain or re-tension while changing flights. This alone will save untold
hours on the routine maintenance of these conveyors”
He goes onto to say “the Bolt ‘n’ Go system has been in service for well over twelve
months, is running great and no problems”.
AVAILABLE SYSTEMS
The Bolt ‘n’ Go chain system is available for 102, 142 and 142mm heavy metric link
ranges. Steel or nylon flights are available. The Bolt ‘n’ Go steel flights are not required to
be as thick as the welded variety, due to the fact that the welded flights are so thick as to
compensate for the weld only. The steel bolt n go flights are very strong as have a consistent
construction, and anything over 400mm width, a further steel backing plate is used
for extra strength and resistance.
The heavy duty nylon flights again bolt straight through the pins, with no need to bolt on
or slide over existing steel flights. The nylon flights also have excellent wear, strength and
resistance capabilities.The Bolt ‘n’ Go pin / bolt assembly system can also be used with the
traditional welded flight system, to replace the traditional pin and circlip arrangement. This
like the bolt n go flight system is very easy to change over to for the maintenance team on
site.The Bolt ‘n’ Go system is also available for round link chain, whereby the system works
under a similar system of nylon flights being bolted directly to the chain, in this case without
pins.

WHO IS
IN THE HORSE
FEED
A cautionary tale
By Darlene Ricker
H
ealth-conscious equestrians have learned to
pay as much attention to what is in their
horses’ feed as in the food on their own
tables. Like grocery store packaging, the label
on a bag of horse feed lists the ingredients from the
highest percentage to the lowest.
What the labels do not say, however, may be the most important variable of all: the source of the
ingredients.
The issue of “who” is in the horse’s feed—known as traceability—was at the crux of an alert in May
involving certain Purina horse feeds. Contaminated grain resulted in a voluntary recall after aflatoxin
was found in Purina horse feeds that had been distributed to dealers in 17 states on the Unites
States east coast.
Purina immediately notified those dealers, who removed the affected lot numbers from their
stock. But traceability could go only so far. Many customers had transferred feeds they had
purchased into their own containers and had discarded the bags on which the lot numbers were
printed. All they could do was watch their horses, wait and hope.
(To date, Purina says there have been no confirmed cases of aflatoxin-related horse illness from its
recalled feeds.)
Traceability in that case was further complicated because neither consumers nor feed manufacturers
knew the answer to the key question: Where had the tainted ingredient come from
A Purina spokeswoman said the company traced the contamination to “a single ingredient from a
single supplier.”
Although it ceased using that supplier, Purina did not disclose its identity or the ingredient at issue.
The possibility remained, therefore, that manufacturers of other brands of horse feeds could
have purchased the same ingredient from the same supplier.
That prompted nationwide efforts in the feed industry to determine the nature and source of the affected
ingredient. Some feed manufacturers and dealers said they had heard the culprit was peanut
hulls (feed ingredient byproducts sometimes contained in less expensive brands of horse feed).
Those reports, however, were unconfirmed, and the company that supplied the contaminated ingredient
to Purina has remained anonymous.

QUALITY CONTROL
QUALITY INGREDIENTS PAY
The incident raised awareness
among horse owners about the
importance of knowing “who” is
in the feed they give their
horses.
While several types of mycotoxins
can harm horses, aflatoxins
are known to be particularly dangerous.
Affected horses may
show signs such as feed refusal,
fever, weight loss, sluggishness
and bloody diarrhea. Worse, the
toxicity can be cumulative.
At levels greater than 50 ppb
(parts per billion), aflatoxins can
cause liver and kidney damage,
jaundice, birth defects, tumors
and can suppress the immune
function. Even at non-critical
levels, they can detract from a
horse’s performance, condition
and appearance. Some have
suggested mycotoxins may also
contribute to colic.
These threats can be reduced by
buying feed from manufacturers
of premium horse feeds, which
utilize ingredients that inhibit the
effects of mycotoxins. (See sidebar
opposite.)
Traceability is also easier to determine
with such manufacturers,
many of whom add to their
feed name-brand products available
only from proprietary
sources.
TRACEABILITY ESSENTIAL
Not all feed companies, however,
are as careful about where ingredients
are purchased from and
subsequent quality testing of
ingredients and additives coming
into their facility, said Dr. Amy
Gill, an equine nutrition consultant
in Lexington, Kentucky, USA.
“Consumers need to be aware of
MYCOTOXINS: PREVENTIVE FEEDING
Given the difficulty of traceability in grain, what can be done to protect
horses from mycotoxins
“One precaution is to routinely add a mycotoxin binder to all manufactured
feeds,” said Dr. Amy Gill, an equine nutrition consultant in Lexington,
Kentucky, USA. While that has not yet become the norm, makers of
premium horse feeds recently began including mycotoxin-fighting products
in their formulas.
Gill noted such additives are designed to “prevent mycotoxins from exerting
their effect in the digestive tract by binding to them and rendering
them inert. When fed on a daily basis with the normal [grain] ration,
the risk of mycotoxin poisoning is greatly reduced.”
Researchers in Canada examined the effects of these additives—referred
to as yeast cell wall polymers or mycotoxin adsorbents)—in 2002 and
2003. Clinical trials were conducted at the University of Guelph’s Equine
Centre in conjunction with its Department of Animal and Poultry Science.
The Canadian feeding trials were done on nine sedentary mature mares
divided into three groups, one of which was a control. The second group
received fusarium mycotoxins in the daily grain ration (a blend of wheat
and corn). The third group was fed contaminated grain supplemented
with a mycotoxin adsorbent.
In comparing the groups, researchers found the mycotoxin effects were
lesser in the horses given the mycotoxin adsorbent. They reported the
supplement alleviated a typical mycotoxin effect: reduced feed intake.
In addition, fewer metabolic changes generally associated with
mycotoxin poisoning were observed in the group that received the mycotoxin
adsorbent. While feeding contaminated grain increased enzymes
associated with liver damage, researchers found that adding the mycotoxin
adsorbent lessened the severity of their effects.
The results of the study, written by Trevor Smith, H.V.L.N. Swamy,
Susan Raymond, were published by the American Society of Animal Sciences
(J. Anim. Sci. 2003. 81:2123-2130).
The research was supported in part by the Ontario Horse Racing Industry
Assn.; the Ontario Ministry of Agriculture and Food; the Rural Job Strategy
Fund; and Alltech, a global animal nutrition company based in
Nicholasville, Ky.
this fact and ask questions if they are unsure of the quality control measures in place for their brand
of feed. If the answers don't suffice, find another brand. Purchasing feed from a reputable manufacturer
lessens the chance of contamination,” she said.
Traceability and ingredient sourcing are the sole responsibility of the feed manufacturer and are

QUALITY CONTROL
“Sure, it’s easier to buy a bag of sweet or complete feed, but
how do you know from week to week what’s in there”
— Richard Ketch, owner of Equine Transitions
based upon the quality control measures a company has in place to prevent contamination of feed
made in its facility, she added, noting that manufacturers are not required by law to divulge the
source of any ingredients.
While cases of horse feed contamination have been rare, even general nutrition concerns underscore
the importance of traceability in horse feeds.
Does it really matter which company manufactured the selenium, for example, contained in some
complete and supplemented feeds
As with numerous other feed ingredients, all selenium is not created equal. A feed whose label lists
selenium as an ingredient may contain the organic or inorganic form. Organic selenium is far more
bio-available—and therefore provides more effective nutrition—to horses than inorganic types.
If the label doesn’t specify the source of its selenium or any other component, consumers can inquire
whether the feed contains the specific name-brand product they desire. Should the answer be no,
one can change to a higher-end feed manufacturer whose formula includes the name brand. Another
option may be to research whether the product can be purchased separately and top-dressed, as can
some organic digestive aids available in feed stores or online.
Taking such extra steps is worth the effort to hands-on horse trainers like Richard Ketch, owner of
Equine Transitions in Lexington, Ky., who has long mixed his own feeds for his string of Thoroughbred
racehorses.
His feeding program is based on whole (unprocessed) grains, such as rolled oats and barley, and individual
organic supplements he uses to “tweak” the recipe for individual horses.
“I am the front-line defense for my own health, and I am the same for my horses,” said
Ketch. “Sure, it’s easier to buy a bag of sweet or complete feed, but how do you know from week to
week what’s in there”
His is a point well taken. Aside from premium horse feeds, whose formulas remain constant, many
manufacturers use least-cost formulation to keep their products attractively priced. That means they
use whichever substitutable feed ingredient byproduct is least expensive at the time. One week it
may contain peanut hulls, the next week corn screenings, perhaps the following month a soy byproduct.
Such variations greatly complicate traceability, making it difficult—if not impossible—to ascertain
exactly what—and “who” is in your horse feed.

posters and mini reviews and workshops.
Overwhelming interest was shown in a workshop dedicated to “Current European legislation
regarding animal/horse feedingstuffs and future perspectives”.
At this workshop, eng. Diederik Standaert reviewed current European legislation regarding
animal/horse feedingstuffs and provided details of the draft proposal for a new regulation
which will replace some of the current legislation.

poses.
This proposal for new EU-legislation has
been discussed with “the industry’ during the
last two to three years and is currently out
for consultation.
The European horse feed industry however,
has not been specifically involved in these
discussions, because there is no official
lobby group for the European horse feed
community.
Eng. Diederik Standaert suggested that the
horse feed community might wish to consider
forming an official group, as part of
FEFAC (Federation of European feed manufacturers).
This would potentially enable the
horse feed community to more effectively
influence European decisions.
If a few key players in the horse feed and
supplement industry initiated such a group
then potentially other companies would follow.
This proposal was supported by the participants
in the final discussion of the Congress.

Plant managers and production managers of
petfood and aquafeed plants travelled to Roermond,
Netherlands from Italy, Germany,
Vietnam, Indonesia, Peru, Honduras, Argentina,
Japan and USA.
Representing companies such as Skretting,
Veronesi and Cargill, they had recently taken
delivery of their new counterflow dryers and
coolers. They came to the course to learn
how to fine tune their drying and cooling process.
Sander Geelen, managing director of Geelen Counterflow explained why the course was set
up: “Even the most fuel efficient car can be driven with high fuel consumption, for example
if you drive it in first gear all the time. It’s the same with dryers. Even though today in our
dryers we can offer the equivalent of “cruise control” and the “fuel consumption indicator”,
we still need our customers to learn how to operate our dryers efficiently”.
During the three day course, participants were trained in subjects such as mass- and energy
balance, moisture uniformity, energy efficiency, automatic moisture control and
preventative maintenance. The course also included interactive sessions on how to calculate
energy consumption, take accurate moisture samples and calculate financial savings.
At the end of the course, participants gave an average score of 9.3 on a scale of 10. The
next Counterflow Dryer and Cooler training will again be in Roermond, Netherlands in the
spring of 2009.

EUROPEAN FEED PRODUCTION MAKES
RECORD GAINS IN 2007
Animal feed production in the EU reached 150 million tonnes, up
by 3.4% on the previous year
I
n 2007 compound feed production
for the EU-27 (excluding Greece,
Malta and Luxembourg) reached
149.8 million tonnes (m/t), i.e.
3.4% higher than the figure for 2006
(145 m/t). This is the highest annual
growth rate registered in almost 20
years. Romania and Bulgaria account for
some 3.5 m/t. To this approximately 1.5
m/t, representing the estimated production
of Luxembourg, Malta and Greece
have to be added to obtain a complete
picture of the compound feed production
in the EU-27.
PIG FEED
The key factor that influenced the compound
feed market was the dramatic
price increase for all key feed materials,
with two main consequences:firstly the high cereal prices encouraged farmers to put their
cereals on the market rather than using them on the farm and secondly livestock producers
facing a huge increase in feed costs, which they could not pass on to consumers of animal
products, turned to the most efficient feed - industrial compound feed.
This was particularly notable in the pig sector, which explains the 3.6% increase in pig feed
production for 2007 on an EU basis.
All EU-15 Member States experienced a growth in pig feed production, although on different
scales (from +0.3 and +0.7% respectively for Denmark and Spain up to 8 and 11% for
Germany and Austria). Poland registered a spectacular 23% growth, while the Czech Republic
and Hungary went down by 11%. Spain remains the
first EU producing country for pig feed with 9 m/t, but Germany has almost closed the gap
between both countries with 8.8 m/t.
POULTRY FEED
With regard to poultry feed, the market share of industrial compound feed versus home
mixing is much higher than for pig feed. This is why the evolution of compound feed production
is more closely correlated with the development of both poultry meat and egg production.
In this regard the increase in poultry feed production is largely influenced by the

recovery of poultry consumption in countries
such as France and Italy, which were seriously
affected by the Avian Influenza crisis.
These two countries, with gains of 3.4 and
4.2% respectively, however recovered only
half the tonnage they lost in 2006 compared
with 2005.
On a European level, poultry feed production
is increasing insignificantly, i.e. up 2.6% from
2006, but only up by 0.9% compared with
2005. France is still by far the leading producing
country for poultry feed.
CATTLE FEED
The most significant increase is for cattle feed
with an increase of 5.3%, but as with poultry,
2006 was a “bad year” for industrial cattle
feed production.
For some countries, the increase may be
explained by the high feed ingredient prices,
which traditionally leads cattle farmers to
prefer compound feed rather than straight
feedingstuffs.
As in 2006, Ireland’s performance was the
opposite of other countries in 2007, with a
drop of 11%, which follows a 16% increase in
in 2006 vs. 2005. The disappointing results
in 2007 may be explained to some extent by
the fact that it was impossible to import corn
gluten feed from the USA due to the application
of the zero tolerance policy for the presence
of non-EU approved events, which particularly
affected Ireland.
Total compound feed production for 2007 is
estimated 3.4% higher than in 2006, with
France, Germany and Spain remaining the
three leading producers.

Manufacturers’ Federation, represents 21 national

Farm animals in the EU-27 consume an estimated
470 million tonnes of feed a year, of which 150
million tonnes are produced by compound feed
manufacturers.

MARKET REPORT
OUTLOOK FOR 2008
According to FEFAC, the following factors are expected to
influence the development of compound feed production in
2008:
• Feed material prices: as in 2007, prices of feed materials
are expected to remain high. EU livestock farmers,
in particular pig producers, can no longer support a 50%
production cost increase and need to pass it on to consumers,
otherwise a significant number of pig holdings
will close in 2008;
• The reduction in pig production: in 2007 pig meat
production reached the top of the cycle and the production in 2008 is expected to
decrease, hence a likely reduction in feed demand.
• The 2% increase in dairy quotas for 2008/09 should in principle result in a higher
demand for feed and especially compound feed, as dairy farmers may not have had
time to adapt and increase the number of animals; therefore, the only solution for
them to increase their production could well be to increase animals’ yields.
• The full recovery of the Avian Influenza crisis for countries which have not seen a
complete return of the market to the pre-crisis levels.
As a consequence, FEFAC experts foresee for 2008 a 1% and 2% increase respectively for
cattle and poultry feed and a reduction of pig feed by 1-2%, hence a total stagnation in
production.

Qualitative Test for Aflatoxin Contamination
Vicam has expanded its line of mycotoxin test kits to include a one-step,
qualitative strip test for the detection of aflatoxin.
AflaCheck is a qualitative, one step, competitive immunoassay method for
the detection of aflatoxin. AflaCheck provides a reliable and inexpensive first
step for testing for the presence of aflaxtoxin without the use of expensive
equipment or reagent chemicals.
“AflaCheck is a vital screening test for grain producers, elevators and processors
who want to ensure that their product is within acceptable limits for
aflatoxin prior to use, storage, delivery and processing,” comments Dr.
Stephen Powers, Director of Research and Development for VICAM. “We are
pleased to provide this highly reliable, rapid and economical testing solution
to our customers in time for their busy harvest season. AflaCheck will save
time and money for our customers by providing a reliable and low-cost
screening step that fits easily into their current quality assurance
protocol.”
Aflatoxin is a potent liver toxin known to cause cancer in animals
and humans. The United States Food and Drug Administration
(FDA) has established action levels of 20 parts per billion (ppb) for
grain and feed products and 0.5 ppb for milk. The European Union
has also established regulations limiting the levels of aflatoxin in
various commodities including animal feed, processed cereals and
groundnuts. Commodities imported into these regions are subject
to inspection, testing and potential rejection or destruction if levels
are above the acceptable established limits.
AflaCheck provides fast and accurate, yes or no results for the
presence of aflatoxin at levels as low as 10 ppb, with an alternative
testing protocol for detecting levels in excess of 20 ppb. This
convenient test is easy to use and provides reliable results in as
little as 3 minutes, in the field or in the lab, and without the use of
expensive equipment or reagent chemicals.

NUTRIGENOMIC BREAKTHROUGH FOR ALLTECH
Alltech, a global leader in animal health and nutrition, has announced its first
breakthrough in the science of Nutrigenomics: EconomasE.
Using his knowledge of the molecular mechanisms of oxidative stress and
intracellular signalling cascades, combined with the science of Nutrigenomics
and the DNA microarray, or gene chip, Dr. Ronan Power, director of Alltech’s
Nutrigenomics Center, was able to identify beneficial gene expression events
in pathways associated with oxidative damage, metabolic stress and macromolecular
repair mechanisms.
Using these genes as a framework, Power was able to create EconomasE,
which will enable animal nutritionists to significantly reduce the level of increasingly
expensive ingredients, such as antioxidant vitamins, added to animal
diets without compromising performance.
“I believe EconomasE is just the beginning of what we will uncover through
the work of Dr. Power and his team at our new Nutrigenomics Center,” said
Dr. Pearse Lyons, president and founder of Alltech.
“Dr. Power’s understanding of gene expression profiling and its impact on
key biochemical pathways within cells and tissues is leading Alltech into a
whole new understanding of animal nutrition for optimal health and performance.”
Power is the architect of Alltech’s Nutrigenomic research program, examining
the effect of nutrition on gene expression. He received a B.S. in Microbiology
and a Ph.D. in Biochemistry from the National University of Ireland.
He completed his Post-Doctoral training in Cell Biology at the prestigious
Baylor College of Medicine in Houston, Texas, where his
work focused on signal transduction biochemistry and, in
particular, the molecular cross-talk mechanisms that exist
between cell membrane-associated receptors and the
nuclear transcriptional apparatus. Working with Alltech
since 1991, Power was awarded the Alltech Scientific Medal
of Excellence this year.

nutritional interventions for peak production potential.
"I, along with everyone at Alltech, am very excited about the potential of
this incredible facility, the first of its kind anywhere in the world," said Dr.
Pearse Lyons, president and founder of Alltech.
"The ability to comprehend nutrition at the most basic level - gene expression
- really makes us stand apart and will give us a much greater understanding
of the nutritional needs of our animals,"
In addition to Nutrigenomics, the facility will house the company's research
initiatives at its global headquarters, including the study of Functional Glycomics,
Solid State Fermentation, Rumen Function and Ecology, Aquaculture,
Organic Trace Minerals and Biorefining.
In coming years, the facility is expected to require 40 additional research
professionals to be fully staffed.
To help address this need, in 2007, Alltech formed a partnership with the
University of Kentucky (UK) to advance research in the field of nutrigenomics.
As part of this partnership, Alltech gave UK a $900,000 grant that will, in
part, help to place faculty and staff from the College of Agriculture at the
company's Nutrigenomics facility.

PROBIOTIC ADDITIVE AWARD FOR QUALITY AND EXCELLENCE
GLOBAL INGREDIENT SUPPLIER, Chr. Hansen,
has been awarded the Grand Prix at
International Veterinary Exhibition.
The product awarded is the probiotic feed
additive Rumenal. Rumenal is developed by
the company Medipharm, which Chr. Hansen
acquired in January 2008. Rumenal is a dietary
supplement used to prevent unbalance
of the mineral and energy metabolisms and
to support the general state of health of
dairy cows.
Medipharm/Chr. Hansen, represented by
Petr Mican, Managing Director, Czech Republic
and one of the drivers in developing
Rumenal, was congratulated on their pioneering
work within probiotics for improving
animal production by the Czech Minister of
Agriculture, Mr. Petr Gandalovic during the
Animal Vetex in Brno, Czech Republic.
“Rumenal provides several advantages to
professional farming. It represents a unique
composition of biological components for
fast recovery of the rumenal microflora. It
enhances the general well-being of the dairy
cows and helps prevent eliminate problems
after calving like e.g. dehydration. Furthermore
it increases milk production and the
general energy metabolism in dairy cows,”
explains Lenka Stankova, Product Manager,
Animal Health & Nutrition, Chr. Hansen.
The product has first been launched in the
Czech Republic, where results are
good. On farms where Rumenal is used

health and nutrition products from Chr.
Hansen and Medipharm. And more will follow.
“We have identified clear synergies and set
our aim high. Together Chr. Hansen and
Medipharm will provide the market with the
world’s best natural silage additives and further
develop and grow the already unique
combination of expertise within feed probiotics”,

NO ROOM FOR SALMONELLA COMPLACENCY SAYS KIOTECHAGIL
WHILE THE UK HAS made significant strides
in reducing salmonella contamination, feed
is still a clear potential route for transferring
salmonella to poultry according to biosecurity
experts at Kiotechagil.
The exact level of risk posed by feed contamination
is very low according to the Veterinary
Laboratories Agency with just 0.6%
of poultry meals and 0.4% of poultry extrusions
testing positive for Salmonella in 2006.
However farmers need to be aware that salmonella
can enter poultry farms through
drinking water, mites and wild animals and
this is particularly important in free-range
operations and for layers and breeders
where housing can become infected.
“This is a genuine concern as even if the
smallest amount of salmonella is ingested
this can potentially multiply inside a bird’s
digestive system and any infected faeces will
rapidly escalate the salmonella count,” says
Kiotechagil’s chief technical officer Murray
Hyden.
In the UK salmonella is believed to be responsible
for around 15 percent of all cases
of food poisoning with one of the key difficulties
being that infected chickens have no
identifying characteristics as these chickens
can go on to lay eggs or to be used as meat.
“Feed additives can be used throughout the
production chain to combat salmonella,”
says Murray Hyden. “Organic acids, well
known for their anti-bacterial properties, are
the basis of these additives. Some such as
Salkil, which was the first blend of organic
acid to use a carrier matrix, can be added
both to clean feed to protect against contamination
as well as to contaminated feed
to rapidly reduce salmonella.
“In addition, because Salkil includes a mineral
carrier matrix, the product passes
slowly through the whole of a bird’s intestine
and providing a platform for the healthy bacteria
to proliferate and in doing so excludes
salmonella throughout the intestines and not
just the early part,” emphasised Mr Hyden.
To complete the biosecurity threats Kiotechagil
also supply a DEFRA approved drinking
water disinfectant and a natural chemical
free treatment against mites and insect
pests for the poultry farmer.
