Using Xylanase, Fresh or Whey Powder Alone or in Combination for Improving Low Energy Broiler Diet Containing Wheat Bran

Abstract

he aim of this study is examine the ability of xylanase (XY), fresh whey (FW), dried whey (DW) alone or in combination to improve broiler low energy diet containing 30% wheat bran (WB). This experiment conducted in Egypt from April to May (23.9 o C-34.8 o C).Two hundred and ten unsexed Cobb broiler chicks seven days old were randomly distributed into seven treatments received control diet, WB (30%) diet,WB+0.1%XY, WB+1% FW,WB+ 0.5% DW, WB+ XY +1% FW or WB+ XY + 0.5 % DW. At 35 days. Birds fed WB diet recorded significantly higher body weight by 2.43% compared to control diet. The birds fed WB +XY was significantly higher in body weight compared to all treatments. Dried whey failed in affecting performance of WB diet. Addition of XY to WB diet significantly increased carcass percentage compared to WB diet or control diet. Wheat bran diet alone increased plasma globulin and phosphorus by 114.8 and 48.54 %, respectively compared to control diet. Xylanase is a suitable additive for WB diet. It could be concluded that the diets containing 30 % wheat bran low energy diet alone or with 0.1% Xylanase improve broiler performance under condition of this study.

Xylanase and Direct-Fed Microbials (DFM) Potential for Improvement of Live Performance, Energy Digestibility, and Reduction of Environmental Microbial Load of Broilers

“…Less amount of feed is required to produce meat and eggs, and fewer excess nutrients are excreted, thus reducing nutrients available for pathogen proliferation in the hind gut and in the litter ( 16 ). The utilization of low-energy diets to demonstrate the potential of xylanase has been adopted by multiple researchers ( 17 , 18 ). Saleh et al ( 18 ) showed that supplementation of xylanase and arabinofuranosidase to diets formulated with 90 kcal/kg less apparent metabolizable energy (AME) than a standard diet improved growth performance, nutrient digestibility, and immune response of broilers.…”
