Abstract:

The current study was carried out to investigate the effect of dietary inclusion of soybean hull on performance, carcass characteristics and blood parameters of broiler chickens from the age of 1 to 42 days. A total of 240 day-old broiler chickens (Ross 308) which were randomly assigned to 4 dietary treatments with 5 replicates of 12 birds in each replicate. Experimental treatments were control diet and diets containing 2.5, 5 and 7.5% of soybean hull. Results of present study showed that, adding the soybean hull decreased linearly and quadratically (P<0.05) the average daily feed intake (ADFI) at starter, grower and the whole period, Inclusion of soybean hull in broilers diets reduced quadratically (P=0.02130) the average daily weight gain (ADWG) at starter period. The addition of soybean hull at grower period and the whole of period improved linearly and quadratically. (P<0.05) the feed conversion ratio (FCR) compared to the control treatment. Supplementing 5 percent of soybean hull in broilers diet significantly (P<0.05) increased the production efficiency factor (PEF) compared with the control diet. None of the carcass characteristics of broiler chickens were affected by experimental treatments (P>0.05). Also, different levels of soybean hull had no significant effect on blood parameters (P>0.05). The concentrations of Alanine aminotransferase in broiler chickens fed 2.5% soybean hull was significantly higher than the control group (P<0.01).  In general, the results of present study indicated that due to the positive impact of soybean hull on conversion ratio and production efficiency factor, it can be used up to 5% in broiler diets.
