EFFECTS OF USING ONION AND GARLIC AS A GROWTH PROMOTER IN BROILER CHICKEN

Abstract

A 42 days long feeding trial was conducted to observe the effects of onion and garlic in broiler diet in terms of improving performance, carcass quality and blood parameters of broiler. Total one hundred and four (104) day-old-chicks (Ross 308) were randomly distributed into four dietary treatment groups having 26 birds in each group. T0 was the control group where no onion and garlic were added. Dietary treatment groups T1 and T2 were fed with the onion and garlic @ 1% respectively where T3 treatment group was fed with the mixture of 0.5% onion and 0.5% garlic. The diets were iso-caloric and iso-nitrogenous for all groups. A significant difference (p<0.05) was found in weekly body weight gain, feed consumption and FCR in different dietary treatment groups at 1st and 2nd weeks of age. But no significant difference was found in carcass quality (drumstick, thigh, breast, wing, neck, leg, head, liver, heart, gizzard, abdominal fat and neck region fat) and serum constituents (cholesterol, glucose, triglyceride, LDL and HDL) in different dietary treatment groups at 1st to 6th weeks of age. This study suggested that the use of onion and garlic as feed additives have little effect on overall growth performance in early stage of broiler chicken.
