      摘要：［目的］探究繁殖营养素对西门塔尔杂交母牛繁殖性能、产后健康及犊牛生长性能的影响。［方法］试验对33头390kg左右妊娠8-9月的初配西门塔尔杂交母牛饲喂不同添加量的繁殖营养，对母牛繁殖性能、产后健康及犊牛生长性能的数据进行分析。［结果］饲喂10g/(头·d)繁殖营养素母牛人工助产率较对照组大幅降低，且犊牛成活率提高，犊牛发病率减少。第一次发情时间提前7.42d，且受胎率也有所提高；饲喂10g/(头·d)繁殖营养素大幅度降低了母牛胎衣不下、子宫炎和乳房炎疾病的发病率；添加了10g/(头·d)繁殖营养素组的犊牛从出生到产后3月龄，其体重和体尺都有不同程度提高。［结论］母牛日粮中添加10g/(头·d)繁殖营养素能提高母牛繁殖性能、降低母牛产后疾病的发生率以及一定程度上提高犊牛的生长性能。

      Abstract: [Objective]To investigate the effects of reproductive nutrients on the reproductive performance, postpartum health and calf growth performance of Simmental hybrid cows.[Method]In the experiment, 33 first-breed Simmental hybrid cows with a gestation of about 390kg in 8-9 months were fed with different amounts of reproductive nutrition, and the data of reproductive performance, postpartum health and growth performance of calves were analyzed.[Result]Compared with the control group, the artificial midwifery rate of cows fed with 10g/(head·d) reproductive nutrients was significantly lower, the survival rate of calves was increased, and the incidence of calves was reduced. The first estrus time was 7.42 days earlier, and the conception rate also increased;Feeding 10g/(head·d) of reproductive nutrients greatly reduced the incidence of afterbirth, metritis and mastitis in cows;The weight and body size of calves in the group supplemented with 10g/(head·d) reproductive nutrients increased to different degrees from birth to 3 months postpartum.[Conclusion]Adding 10g/(head·d) reproductive nutrients to cow diet can improve the reproductive performance of cows, reduce the incidence of postpartum diseases and improve the growth performance of calves to a certain extent.
