| 摘 要： | 试验通过对比舍外散放蛋鸡与舍内笼养蛋鸡在体重、胫长和胫围等方面的差异来研究饲养方式对鸡产蛋前期生产性能的影响。结果表明：散放鸡体重在8、10、12周龄显著低于同周龄笼养鸡;散放鸡胫长在10、12周龄显著低于同周龄笼养鸡;散放鸡胫围在10周龄显著低于同周龄笼养鸡。笼养鸡和散放鸡各周龄的胫长和胫围变异系数均小于10%,均匀度均高于或等于80%。两组蛋鸡各周龄体重的变异系数均小于10%,体重均匀度呈逐级递增状态,6周龄蛋鸡体重均匀度较低,到12周龄时均匀度已达到80%。两组蛋鸡的生产性能各指标均达到海兰褐蛋鸡饲养标准。

| Abstract: | The purpose of this study was to test the effects of feeding model on hens production performance in the early laying period through difference comparison in body weight,shank length and shank girth.The experimental results indicated that the body weight of the free-range hens is significantly lower than the caged hens in 8,10,12 week age,and the shank length of the free-range hens is significantly lower than the caged hens in 10,12 week age,and the shank girth of the free-range hens is significantly lower ... |
