Effect of Various Levels of Roasted Fullfat Soybean and Methionine on Performance and Blood Parameter of Male Broiler Chickens

Abstract

To investigate the effects of different levels of roasted fullfat soybean and methionine on performance of broilers,an experiment was conducted in a completely randomized design on 312day-old male broilers Ross strain with 6 treatments(three levels roasted soybean 0,8,12 and two levels of DL-methionine 100 and 110% Ross(2007)recommendation)and 4 replications(13broilers per replicate).The experimental period was 42 days(starter 0-10, grower11-24, finisher25-42)and diets were provided isocaloric and isonitrogenous. All birds were fed ad libitum. The same management system was adopted for all birds, reared in 24 floor pens in a poultry house. Feed intake, weight gain and FCR were measured at the end of every period. At the end of production period, broilers were weighed; blood samples (5cc) were obtained and slaughtered. The results showed that addition of roasted fullfat soybean to diet had significantly affected weight gain, FCR and feed intake in the finisher period(p
