摘　　要：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。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.
