摘　　要：为研究日粮中添加不同水平的巴尔麦氏对罗曼父母代蛋种鸡生产性能的影响,试验选择15周龄的罗曼父母代蛋种鸡400只,随机分为4组,每组100只。对照组饲喂基础日粮,试验1,2,3组在基础日粮中分别添加1‰、2‰、3‰巴尔麦氏,试验期为210 d。结果表明：在27~30周龄时,试验2组蛋种鸡产蛋率显著高于对照组（P〈0.05）,料蛋比显著低于对照组（P〈0.05）;试验3组蛋种鸡产蛋率显著低于对照组（P〈0.05）,料蛋比略高于对照组,平均蛋重显著高于对照组（P〈0.05）,但开产日龄比对照组稍晚;试验1,2,3组蛋种鸡繁殖性能指标与对照组差异不显著（P〉0.05）。说明日粮中添加巴尔麦氏可以提高罗曼父母代蛋种鸡产蛋期生产性能;巴尔麦氏的适宜添加量为2‰。To study the effects of adding different levels of Powermix to the diet on the productive performance of Roman parental egg - laying breeders, 400 Roman parental egg - laying breeders at 15 weeks of age, were randomly divided into four groups of 100 breeders each. The control group was fed based diet, and there experimental groups were fed the basic diet supplemented with 1%, 2 % and 3 % Powermix. The trial period was 90 d. The results showed that the laying rate in the experimental group 2 was significantly higher （ P 〈 0.05 ） than that in the control group from 27 to 30 weeks of age, while the feed to egg ratio in the experimental group 2 was significantly lower （ P 〈 0.05 ） than that in the control group. The laying rate in the experimental group 3 was significantly lower （ P 〈 0.05 ） than that in the control group from 27 to 30 weeks of age , and the feed to egg ratio in the experimental group 3 was slightly higher than that in the control group ; the average egg weight in the experimental group 3 was obviously higher （ P 〈 0.05 ） that of the control group, but the age at first egg was slightly later than that of the control group. There were no significant differences （ P 〉 0.05 ） in the indexes of reproductive performance between all experimental groups and the control group. The results indicate that adding Powermix to the diet can improve the productive performance of Roman parental egg - laying breeders during the laying period, and the suitable addition amount of Powermix was 2 %,.
