To determine the effect of feed acidification on the carcass characteristics of broiler chicken, four treatments were formed (of 48 chickens each) together with control. The chicks in the treatment 1 received antibiotic - furazolidone (200 mg/100 kg) and treatment 2 included acidifier 1- mixture of formic acid and lactic acid, treatment 3 were fed acidifier 2- butyric acid acidifier and treatment 3 was given acidifier 3-prepared in laboratory by mixing copper sulphate, lactic acid and water in the ratio 1:2:3 respectively. The acidifiers in the feed were at the rate of 50 mg/100 kg for starter followed by 50 mg/kg in the finisher. For studying the carcass characteristics 3 males and 3 females per treatment were slaughtered and their carcass characteristics liver, heart, gizzard weight were recorded. The weight and their dressing percentage were calculated. Neither the antibiotic nor the acidifier diet showed significant effect on the carcass characteristics.
