不同地区小麦养分含量差异及其肉仔鸡养分利用效率的比较

摘要

A total of 15 wheats samples were collected from different regions and the nutrient contents and nutrient utilization efficiency in broilers were determined.The results showed that:wide variation in wheats nutrition contents exist-ed,the variation coefficients of ether extract,neutral detergent fiber and acid detergent fiber were over 10%.Significant differences were also observed in nutrient utilization efficiency of broilers,the variation coefficients of crude protein appar-ent utilization reached 14.17%,and the variation coefficients of apparent ileal digestibility of dry matter and general ener-gy,IDE were also over 10%.Contrast comprehensively,the optimal feeding effect was observed in No.3 and No.6 wheat, while the worst feeding effect was obtained in No.4,No.5 and No.12 wheat diet group.%试验研究了来源于不同地区的15种小麦养分含量的差异及其肉仔鸡养分利用效率。试验结果表明：不同来源小麦常规养分含量存在较大差异，其中脂肪、中性洗涤纤维和酸性洗涤纤维变异度均在10%以上。肉仔鸡对不同来源小麦养分利用效率间存在显著差异，蛋白质表观利用率变异高达14.17%；干物质、总能回肠表观消化率和回肠表观消化能（IDE）变异度也均在10%以上；综合考虑各生产性能指标，3号（河北保定）和6号（河南鹤壁）小麦饲喂肉仔鸡效果最优，4号（河南鹤壁）、5号（河南鹤壁）和12号（江苏南通）小麦饲喂肉仔鸡效果最差。
