| 摘 要： | 为了提高珍珠鸡的产蛋性能和经济效益,进行了本次试验.本试验为期3个月,试验取样250只30～32周龄,健康无病、体重基本一致的产蛋珍珠鸡,随机均分为5组,研究了5组不同蛋氨酸含量对产蛋量、蛋重、料蛋比及孵化性能的影响.结果表明日粮中添加适宜的蛋氨酸不仅能够显著地提高产蛋量和蛋重,而且还能提高饲料报酬,同时种蛋的孵化性能也有所提高.珍珠鸡产蛋期日粮中最适宜的蛋氨酸水平为0.42%.

| Abstract: | To enhance the laying performance and economic benefit of keets,250 30-week-old laying keets were randomly divided into five groups to study the effects of different contents of methionine on egg yield,egg weight, feed egg ratio and hatching performance. The results showed that laying cycle diet supplementing suitable content of methionine could enhance egg gield,egg weight,feed egg ratio and hatching performance obviously. The most suitable content in diet was 0.42%. |
