2012/13 - GGI German Genetics International GmbH

GGI - German Genetics International GmbH
GGI − German Genetics International GmbH is the international export marketing body of the nine leading German breeding
organizations, representing these on the international market. As well as a wide range of sires of beef, dual purpose and
other dairy breeds, we offer, in particular, high-class Holstein and Red Holstein genetics. In co-operation with our competent
partners worldwide, GGI offers breeders from all over the world access to the entire potential of
German Holstein breeding. Moreover, GGI is a reliable partner for all aspects of cattle breeding and
management. All sires offered are tested with high reliability and accuracy, based on the worldwide leading
estimation model for breeding values. This applies to daughter proven sires as well as to only
genomic tested young bulls. The German breeding philosophy is clearly reflected in GGI’s product range.
This includes high milk production with good components, good conformation with excellent feet & legs
and functional, healthy udders as well as high fertility and great longevity. The aim is an efficient, healthy,
trouble-free cow that gives high production under a variety of housing conditions over many lactations.
Please contact GGI or our international partners because using the best GGI sires you will always be on the right track!
Daughter proven sires and genomic selection: a question of reliability
Since August 2010, all breeding values have been enhanced by including genomic information in order to increase reliability,
especially of young daughter proven bulls. As well as established daughter proven bulls, since August 2010, bulls with only
genomic breeding values have the status of a tested sire as well.
Genomic breeding values are calculated with the help of the young bull’s genome structure by comparing this with the genes
of the daughter proven sires (reference sample). Consequently, the quality of the genomic breeding values directly depends
on the quality of breeding values on a daughter basis and the number of bulls included in the sample.
Germany has the largest and best structured reference sample in the world with more than 23,000
sires (August 2012). This sample represents the entire, up dated Holstein genetics
population from Europe and North America so that the predominance of the German
breeding value estimation system will remain for genomic selection, too. Due to the
much shortened generation interval, young bulls mostly get clearly higher breeding
values than recent daughter proven sires. However, it should be kept in mind that
the reliability of only genomic tested bulls is significantly below the daughter proven
sires’.
That is why GGI provides a wide range of only genomic young bulls without daughters,
young daughter proven hopefuls with a few hundred daughters and solid second crop sires with several thousand
daughters.
It does not matter what you are seeking for your herd: GGI will have it!
To give you a quick overview of top-class German genetics,
you can find in this catalogue both daughter proven sires with
high reliability and genomic bulls who will bring faster breeding
progress

The specifications regarding the breeding values are based on computer models of the vit in Verden. Specifications regarding the health status of the bulls result
from tests done by national and international laboratories. For the correctness of the above-mentioned results GGI does not assume any liability.
