饲养方式对蛋鸡产蛋前期生产性能的影响
Effects of Feeding Model on Hens Production Performance in The Earlylaying Period
摘要
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 than the caged hens in 10 week age. The CV(Coefficient of Variance) of hens shank length and the CV of hens shank girth are lower than 10% under two feeding model, and the uniformity of hens shank length and shank girth is equal to or higher than 80%. The CV of the hens body weight is lower than 10%, the uniformity of the body weight is increased along with week age. The uniformity of the 6 week hens' body weight is low, but the uniformity of 12 weeks ages has achieved 80%. The hens production performance under two feeding model is conform to the production standards of the hy-line brown.关键词
