Alliaceae and the genus Allium is widely distributed and used in all over the world as a spice
and herbal remedy for the prevention and treatment of variety of diseases (Javandel et al.,
2008). The key active ingredients in garlic is a powerful plant chemical called allicin which
rapidly decomposes to several volatile oregano-sulphur compounds and it also contains
organic sulphurous compounds such as allin, ajoene, ally propyl disulfide, dially trisulfide
(Mansoub,2011). Moreover, garlic is very rich in aromatic oils, which enhances digestion and
positively influenced respiratory system being inhaled into air sacs and lungs of bird.
Therefore, present investigation was planned to study the effect of black cumin and garlic as
a natural feed additive on growth performance of Kaveri chicken with the following
objectives
Methodology
The Black cumin seed was mixed in basal diet as per treatments. Garlic was manually descaled
and crushed with the help of grinder and subjected for hot air oven drying process at 50 0 C for 8
hours. Ccommercial pre-starter, starter and finisher was procured from local market. Total three
trials were conducted and every trial was conducted on 200-day old Kaveri chicks; obtained from
local hatchery. On arrival, the chicks were weighted individually and randomly divided into five
treatments with four replications and each replication has ten birds. Electric brooder was used to
provide sufficient heat and light for first week of age.
Birds were reared on deep litter system using dry paddy husk in a well-ventilated house. A
weighed quantity of feed was offered ad-libitum to the experimental birds distributed in each
treatment throughout day along with Fresh, clean, cool, potable drinking water. drinkers, feeders,
and other equipment were cleaned and disinfected with 0.02% KMno4 solution every day. Lime
was applied on side walls and floor with the aim to reduce the infestation before each trial. The
treatments were T1- Basal diet (Control); T2- Basal diet + Antibiotic (BMD @ 250g/Tonne of
feed); T 3- Basal diet + 1% Black cumin seed; T 4- Basal diet + 1% Garlic mash; T 5- Basal diet +
0.5% Black cumin seed + 0.5% Garlic mash.
