Different Dietary Source of Non-Starch Polysaccharides Supplemented with Enzymes Affected Growth and Carcass Traits, Blood Parameters and Gut Physicochemical Properties of Broilers
Journal Title: Global Journal of Animal Scientific Research - Year 2015, Vol 3, Issue 2
Abstract
An experiment was conducted to evaluate the effect of different dietary source of Non-starch polysaccharides supplemented with enzymes on growth, carcass and physiological characteristics of broilers. A total number of 625 unsexed broiler chicken (Ross 308) were randomly assigned to 5 treatments, 5 replicates and 25 birds per each unit, using a CRD statistical design. Treatments were included control, wheat (W), wheat+ enzyme (WE), barley (B), and barley+ enzyme (BE). Total feed intake and body weight gain were significantly increased, but feed conversion ratio decreased by diets supplemented with enzymes rather diets without enzymes (P<0.05). The inclusion of W and B in diets led to significantly decreased in carcass yield and the percentage of breast, leg, fat pad, and liver compare to the control (P<0.05). The percentage of pancreas was higher in W and B diets than control or enzyme supplemented diets (P<0.05). Serum levels of glucose (GLU), triglyceride (TG), and cholesterol (CHO) significantly decreased in diet contained W and B (P<0.05). Digesta viscosity significantly increased, but pH decreased after feeding the chickens by W and B diets rather control (P<0.05). The results of present study have shown that supplementation of W and B with multi-enzymes completely restored the situation and neutralized the negative effects of W and B on growth and carcass traits, blood parameters and gut physicochemical properties of broiler chickens.
