【 摘 要 】

The experiment was conducted to investigate the effects of different fat sources on growth performance ofbroiler chicks. Broiler chicks were raised from 0 to 50 days of age. Two hundred and forty broilers (Ross 308) wererandomly assigned to one of four experimental diets. These were four replicates for each of the following diets: A)Soybean oil, B) Free fatty acids, C) Grease oil, and D) Poultry oil. The results showed that the highest body weightand daily weight gain in 8-15 d, 16-25 d, 26-39 d, 40-44 d, and 45-50 were obtained in broilers fed on soybean oildiets (P<0.05). In 0-50 day oil the feed intake and daily weight gain of broilers fed on soybean oil was higher thanother fat sources (P<0.05). According to findings of recent study, the growth performance of broiler fed on poultryoil and grease oil was poor compare to other fat sources. The growth performance of broilers fed on free fatty acidsdiet was slightly better than grease oil and poultry oil sources. The soybean meal oil and poultry fat oilsupplementation significantly increased and decreased carcass weight percentage, respectively (P<0.05). Antibodytiter against Newcastle diseases and Influenza viruses were not affected by different fat sources (P>0.05).
