| 摘 要： | 对９４５只１２５日龄的伊莎商品蛋鸡不同体重组（Ａ组１６００ｇ以上、Ｂ组１４００ｇ～１５９９ｇ和Ｃ组１４００ｇ以下）进行早期（１９～２５周龄）产蛋性能的观察结果：体重在开产前达到１６００ｇ以上时提前开产，达５％、５０％和８０％的产蛋率日龄，体重最重的Ａ组比Ｂ组分别提早７、４和１天，比Ｃ组分别提早１４、７和４天；试验期内的产蛋量，Ａ组比Ｂ组多产蛋６４９枚，合４６．２４ｋｇ．，比Ｃ组多产１６８３枚，合１０９．６５ｋｇ；蛋重与体重呈正比，平均每枚蛋重，Ａ组比Ｂ组多１．４６ｇ，比Ｃ组多２．４２ｇ；在死亡率上，体重最轻的Ｃ组抗病力差、死亡率大，Ｃ组＞Ｂ组＞Ａ组，在经济收益上，各组所创产值是Ａ组＞Ｂ组＞Ｃ组．

| Abstract: | ISA Brown layers were divided into group A (over 1600g) ,Group B (1400g1599g) and Group C (below 1400g) according to the hody weight at the age of 125 days in order to observe the effect of body weight on laying performance. The results showed that group A reached the ages of laying rate of 5%, 50% and 80%, 7. 4 and 1 days ahead of group B and 14, 7 and 4 days ahead of group C. Group A produced 649 and 1683 more aggs than group B and C,respeCtively. When the body weights increased,egg weight, profit and viability during laying period increased. |
