Abstract
The effects of corn and soybean meal substitution by the graded levels of low tannin Faba bean in broiler finisher pellet diets on performance, carcass characteristics, and some biochemical and gastrointestinal tract parameters of broiler chickens were investigated. 2000 one-day-old Ross broilers were fed a corn-soybean meal-based diet for the starter and grower period. Then 600 birds with almost similar weights (near the standard weight) were selected and divided into four treatments with 5 replicas (30 birds for each pen) to consume the experimental diets for 20 days (from 24 to 44d). The experimental diets were: control group corn-soybean meal-based diet without fava bean 3 other groups were fed 7/5, 15, and 25% faba bean, respectively. There was no difference in average daily feed intake (ADFI), average daily gain (ADG), and feed conversion ratio (FCR) among 4 experimental groups (P>0/05). Only birds received 15 and 25% faba bean had significantly lower total cholesterol in comparison with the control group (P<0/05). The results of carcass quality showed that only feeding 15% faba bean significantly increase l* indicator and breast muscle protein (P<0/05). This study showed that different levels of Faba bean (7/5, 15, and 25%) can be used in broiler diet finishers without any negative effects on birds' performance. Even though feeding all levels of low-tannin faba bean reduced the feed cost per kg live body weight in comparison with the control group, but the most economical level for using low-tannin faba bean in broiler feed was 7/5%.
