摘要
在农湖2号蛋鸭选育过程中,改进和完善了蛋鸭阶梯式笼养技术。2020年,结合农湖2号蛋鸭选育基地全面改造,阶梯式笼养技术取得突破性进展。通过对光照制度、通风频率等5个方面的技术改进,农湖2号蛋鸭阶梯式笼养最高产蛋率从90.5%提高到97.5%,产蛋高峰持续时间从5个月延长到8~10个月,产蛋中后期腹水症发生率从1.7%下降为0,产蛋期死亡率从3.61%下降到2.42%。1个产蛋周期中,每只母鸭产蛋增收11.20元。
In the breeding process of Nonghu No.2 laying ducks,the ladder cage breeding technology of laying ducks was improved and perfected.In 2020,combined with the comprehensive transformation of Nonghu No.2 laying duck breeding base,the ladder cage technology has made breakthrough progress.Through technical improvement in five aspects,such as lighting system and ventilation frequency,the highest rate of egg production of Nonghu No.2 laying duck were raised from 90.5%to 97.5%in ladder cage raised;the duration of egg production peak was extended from 5 months to 8~10 months;the incidence of ascites disease in the middle and late stages of egg production was decreased from 1.7%to 0;the mortality rate in egg production period was decreased from 3.61%to 2.42%.In one laying cycle,the egg production income of each female duck increased by 11.20 yuan.
