肉种鸡笼养综合限饲方案适合性的研究

STUDY ON STITABLITY OF SYNTHETICAL FEEDING RESTRICTION PROGRAM IN BROILER BREEDER CAGE

以父母代肉种鸡平养喂料标准为对照，依次降低８％、１０％和１２％进行肉种鸡笼养的综合限饲方案适合性试验。结果表明，以平养喂料量降低１０％的处理为最佳，体重符合标准要求，生产性能也最高（Ｐ＜０．０１）。此外，在１８～２３周龄饲喂１８％蛋白质水平的日粮，能够使笼养肉种鸡适时开产，避免开产日龄及产蛋高峰延迟的现象。

Making use of level ground feeding standard of AA parent brider breeder to control group. successively reducing 8%,10% and 12% to experiment group, adoptting synthetical feeding restriction program (SFRP)to do experiment in brider breeder cage. The results showed that the group reducing 10% on the basic level feeding standard is beteer, body weight echo standard, production perfermance is better (P < 0.01). Moreover, feeding 18%protein levels ration for brother breeder cage in 18～ 23 week age be able to lay in good time and avoid delay on age at 50% producion and peak production;
