| Abstract | ||
| An experiment was conducted to study the effect of partial and total substitution of the sesame seed meal instead of protein concentrate in broiler ration, on broiler (Ross strain) performance. Three rations were used to substitute sesame seed meal instead of protein concentrate, Treatment 1 was the control group which contain 100% animal protein concentrate, with out sesame meal, treatment 2 contain 80% animal protein concentrate and 20% sesame meal, while the third treatment contained no animal protein concentrate, 100% sesame seed meal, The total protein and energy contents were same in all rations. Live body weight, weight gain, feed intake and feed conversion coefficient were calculated, for periods 4 and 8 weeks of age. Live body weight at 4 and 8 weeks were (846.25, 850.00, 835.06 and 2614.06, 2585.00,2620.31 g. , respectively). Results showed that no significant differences were obtained in body weight, weight gain during 4 and 8 weeks of age for all treatments compared with that of control group (846.25, 850.00, 835.06 and 2614.06, 2585.00,2620.31 g., respectively), for body weight and (28.60, 28.78 , 28.22 and 63.13 , 62.00 , 63.75 g., respectively) for weight gain , for birds in treatment 1 (control), 2 and 3 , for both periods . Carcass weight and dressing percentage at 8 weeks of age were also determined .The results indicated a significant difference in feed intake at 28day of age, and there was an increasing feed intake with increasing substitution percentage in the third treatment. There was a decrease in feed intake during the period of 1 - 56 days. The total amount of feed intake during 56 days the second treatment and the control was 4678.7 and 4692.9 g. for the second treatment .The results indicated no significant difference in feed efficiency and dressing percentage for all treatments at 56 days. From this study it could be concluded that using sesame meal had no harmful effect on broiler performance. | ||
