This research was carried out using a total of 60 one-day old chicks from
hybrid broiler (Hubbard). Opened house system was used for rearing on floor
pens. The chicks divided randomly into three equal groups. The first group
considered as a contro
l which was fed on a ration without supplementation of
Garlic Powder (0.0%). while the second and third were fed on a ration
supplemented with Garlic Powder by (0.5%) & (1%) respectively. All
treatments were applied beginning from one-day chicks old up to sixth week of
age. The results showed that the supplementation of Garlic Powder (0.5%) and
(1%) led to improve broiler performance: significantly increase (P<0.05) was
noticed in final live body weight 5.12 % and 3.54%; weight gain 5.26 % and
3.62% respectively comparing with control, improve feed efficiency 7.57% and
8.86%, decrease feed consumption 2.69% and 5.54%.
