Original Article Effect of Adding Aloe Vera Gel and Garlic Powder on Carcass Characteristic and Internal Organ Mass of Broiler Chickens

The present study was designed to evaluate the effects of supplementing different levels of Aloe vera gel and garlic powder on carcass characteristic and internal organ mass of broiler chickens. For this purpose, one hundred and sixty, one-day-old, Ross chicks were used, in completely randomized design, in four treatments and each with four replicates. The treatment groups consisted of: control group fed only with non-supplemented basal diet, group 2 supplemented with 3 % aloe vera in drinking water, group 3 supplemented with 3 % garlic powder in diet and group 4 supplemented with 1.5 % aloe vera in drinking water + 1.5 % garlic powder in diet, which were reared for 42 days. The result of this experiment showed no significant difference (P>0.05) in internal organs weight like gizzard, spleen, bursa of fabricius, provintriculus and abdominal fat at 42 days of age between control and treated groups. The other results of this investigation showed that broilers receiving Aloe vera gel and garlic powder had lower abdominal fat relative weight (P>0.05) compared to control group. However, the highest thighs, breast and total carcass weight
