Abstract:   (268 Views)

An experiment was conducted to evaluate the effects of wheat and wheat bran diets with and without enzymes on growth performance and digestive characteristics of broilers. A total number of 625 one day old Ross-308 broiler chickens were allocated randomly to 5 treatments with 5 replicates, using a CRD statistical design. Treatments were control, wheat, wheat+ enzyme and wheat bran and wheat bran+ enzyme. Traits were growth performance, carcass characteristics, ileal microbial counting and measurement of gut acidity and viscosity. According to the results, effect of different treatments on all experimental traits at starter and finisher periods were significant (P<0.01).  Minimum growth performance and maximum feed conversion rate at the whole rearing period belonged to treatments without enzymes. Supplementation of wheat and wheat bran with enzymes resulted in significant improvement of growth performance traits compare to control group (P<0.01). Effects of different treatments on carcass characteristics were significant (P<0.01). The highest carcass performances belonged to control group, but supplementation of wheat and wheat bran with enzymes resulted in significant improvement of carcass performances (P<0.01). Effects of different treatments on the intestinal microbial population were significant (P<0.01). Maximum undesirable bacteria were observed in treatments without enzymes, but maximum desirable bacteria were observed in treatments supplemented with enzymes. Digesta acidity and viscosity were lower and higher in the treatments without enzymes respectively (P<0.01). Supplementation of wheat and wheat bran with enzymes improved these digestive properties (P<0.01). In conclusion, inclusion of wheat and wheat bran in broiler corn-soy based diets were conceivable and supplementation of wheat and wheat bran diets improved the growth and carcass performances.
