| 摘 要： | 采用饥饿法对艾维茵父母代肉种鸡进行强制换羽观察,试验鸡群6 369只,为62周龄母鸡.换羽前平均体重4 230 g,产蛋率35%.对换羽期死淘情况、体重变化、产蛋率变化进行观察记录.结果表明:强制换羽后42天见蛋,见蛋后6周产蛋率上升到66%,种蛋平均合格率95%以上;恢复产蛋前死亡155只,占全群2.43%,第2周死亡最多,达38只;换羽第4周累计失重920 g,失重率21.7%.该次换羽结果较理想.

| Abstract: | Starving method was used to study the forced molting of Avian parent stock,6 369 hens at 62 weeks of age were involved in this thesis.The average body weight before molting was 4 230 gram,and the average rate of egg production was 35%.The results showed that: First egg was laid after 42 days,and 6 weeks later,the average rate of egg production rose to 66%.Qualified egg rate was up to 95%.Death quantity in the second week after molting was most,the death rate before laying was 2.43%.The total body weight loss was 920 gram in 4~(th) week after molting,the total loss rate was 21.7%. |
