Effect of dietary supplementation of garlic (Allium sativum) on weight gain and cholesterol level in broilers

A biological trial was conducted for a period of 6 weeks to study the effect of graded levels of Garlic (Allium sativum) supplementation on growth performance and muscle cholesterol including serum lipid profile in broilers. The body weight was significantly increased (P<0.01) along with decreased (P<0.01) feed consumption and better FCR in group receiving 1%garlic. Serum total cholesterol, triglyceride, LDL-Cholesterol values were significantly reduced (P<0.01) and serum HDL-Cholesterol value was significantly increased (P<0.01) in the garlic supplemented group as compared to control group. Therefore, 1% garlic supplementation in broiler ration may be effective for improving growth performance with reduced muscle cholesterol concentration and beneficial serum lipid profile.
