摘    要:分析5250只26周龄的艾维茵48父母代种鸡的产蛋情况并与标准比较,了解产蛋期肉种鸡产蛋性能的变化规律及饲养管理情况。结果表明,随鸡群周龄的增大,累积死淘率逐渐上升,且在产蛋末期明显上升;鸡群产蛋率在26-30周龄低于标准,在产蛋末期产蛋率下降幅度增加;鸡群的合格蛋率相对较高;合格蛋受精率在26-34周龄上升缓慢且低于标准受精率,此后呈波动性缓慢下降,且始终低于标准受精率。在种鸡生产中,加强饲养管理可以提高种鸡产蛋性能。

关 键 词:艾维茵肉种鸡  产蛋性能  种蛋

Abstract:Laying performance of 5250 Avian 48 parents breed was analyzed and compared with the "Avian parents breed farming guide" from the ages of 26 to 62 weeks for learning the laying rules and the feeding a~ld management of broiler breeder.The result showed that the cumulative mortality rate increased gradually as the week age older.The cumulative mortality rate was higher at the end of laying.The laying rate in the age of 26 to 30 weeks was lower than that in the guide. The decline trend was increasing at the end of laying.The hatching egg rate was higher than that in the guide.The f~rtilization rate was increased slowly in the age of 26 to 34 weeks and lower eomparing with that in the guide. After that,it decreased slowly in w~latility.The laying perfornianee would be better by improving the feeding and management of broiler breeder.
Keywords:Avian broiler breed  Laying performance  Hatching egg
