Evaluation of production index, protein and energy efficiency indices, biochemical blood traits and humoral immunity in broiler chickens fed different level and particle size of insoluble non-starch polysaccharide of rice and oat hull

To evaluate the effect of type (Rice Hull (RH) and Oat Hull (OH)), level (3 and 6 percent) and particle size (0.5 and 2 mm) of insoluble fiber on performance, production index, protein and energy performance, blood indices, lymphoeid tissue and humoral immunity of chickens, 360 day-old male broilers (Ross 308), were use in a completely randomized design with 9 treatment and 4 replicate with 10 birds each, for 42 days. In the 29-42 days, broilers fed 6 percent with 0.5 mm RH had higher (P≤0.05) average daily gain, daily feed intake and lower feed: gain than control group. For the 1-42 days, broilers fed OH had best production index (P≤0.05) than broilers fed the control diet. In this experiment, the effect of fiber, level and particle size was not significant effect on energy and protein performance, lymphoeid organ, humoral immunity and blood indices. Therefore, it is concluded that inclusion of 3 percent RH with 0.5 mm particle size to broiler diets may improve the growth performance and production index.
