The Effect of Garlic (Allium sativum) Extract on Performance, Abdominal Fat and Serum Cholesterol of Broiler

The present study was conducted to determine the effects of garlic extract on performance, abdominal fat, and serum cholesterol of broiler up to six weeks of age. One hundried and eighty 2-wk-old broiler were colony caged in an environmentally controlled house to evaluate the effect of garlic (Allium Sativum) extract administration on performance, abdominal fat, and serum cholesterol. Garlic extract was prepared by blending pealed garlic cloves with distilled water (1:1, w/w). Birds were randomly divided into three equal groups; one served as a control and the other two groups were offered 2.5% and 5% Garlic extract of drinking water. Garlic extract increased (p<0.05) body weight ganis and feed efficiencies with no change (P>0,05) in feed consumption. Garlic extract administration recorded lower (p<0.05) abdominal fat and serum cholesterol contents. In conclution, 2.5%-5.0% garlic extract on drinking water improved performance and may decrease both abdominal fat and serum cholesterol of broiler up to six weeks of age.
