对49日龄国外引进的白羽肉鸡WL、白羽肉鸡WA、黄羽肉鸡YH以及国内培育的黄羽肉鸡YW等4个肉鸡品种的商品代骨骼强度进行测定比较,结果显示:①不论公母,白羽肉鸡股骨、胫跗骨骨骼强度显著高于黄羽肉鸡(P＜0.05),黄羽肉鸡YW跗跖骨骨骼强度显著低于白羽肉鸡WA(P＜0.05);白羽肉鸡母鸡单位股骨、跗跖骨骨骼强度所承受的体重显著高于黄羽肉鸡(P＜0.05).②除白羽肉鸡WL胫跗骨外,白羽肉鸡骨骼强度母鸡均显著低于公鸡(P＜0.05);白羽肉鸡WA单位跗跖骨骨骼强度所承受的体重公母之间差异显著(P＜0.05).③白羽肉鸡无论是骨骼强度还是单位骨骼强度所承受的体重,不同部位之间差异显著(P＜0.05);黄羽肉鸡股骨与跗跖骨、胫跗骨与跗跖骨之间差异显著(P＜0.05).
