摘要：

为探究淫羊藿对小尾寒羊繁殖性能的影响及其合适的添加比例，选取192只6月龄小尾寒羊，公母各半，根据体重随机分为4个公羊组和4个母羊组，每组24只分成3个重复，每个重复8只，分栏饲养，其中种公羊每只单栏饲养，对照公羊组和对照母羊组饲喂基础日粮，3个公羊试验组和3个母羊试验组分别在日粮中添加0.5%、1.0%、1.5%的淫羊藿，进行75 d饲养试验，测定淫羊藿对小尾寒羊繁殖和血液生殖激素的影响。结果显示：淫羊藿可增加公羊饲料消耗，促进生长发育，不同程度提高公羊的精液量、精子浓度、减少畸形率、提高公羊血液睾酮浓度，其中1.0%淫羊藿组比对照组差异显著(P<0.05)，1.5%淫羊藿组比对照组差异极显著(P<0.01)，但饲料消耗和料重比增加；淫羊藿可促进母羊生长发育，减少饲料消耗，但统计学差异不明显(P>0.05)，可以不同程度提高母羊产活羔量、产羔率、促卵泡生成素(FSH)、促黄体生成素(LH)浓度，1.5%淫羊藿组比对照组差异显著(P<0.05)。试验表明，精饲料中添加一定比例的淫羊藿能提高小尾寒羊公羊和母羊的繁殖性能，增加公羊饲料消耗但不增加母羊饲料消耗，并有助于提高机体免疫力。研究以期为合理利用淫羊藿来提高小尾寒羊的繁殖性能提供一定的技术参考。

Abstract:

This experiment was conducted to study the effects of epimedium on the reproductive performance of Small Tailed Han sheep and the appropriate addition ratio in the feed. A total of 192 six-month-old Small Tailed Han sheep, half male and half female, were randomly divided into four male groups and four female groups. Each group of 24 sheep was divided into 3 replicates with 8 sheep in each, and housed in separate pens. The control male and female groups were fed a basal diet, while the three male test groups and three female test groups were fed a diet containing 0.5%, 1.0% and 1.5% epimedium, respectively, for a 75-day feeding trial. The results showed that epimedium could increase the feed consumption of male sheep, promote growth and development and improve the sperm volume, sperm concentration, and reduce the abnormal rate of male sheep to varying degrees, and increase the blood testosterone concentration of male sheep. Among them, the 1.0% epimedium group was significantly different from the control group (P<0.05), and the 1.5% epimedium group was extremely significantly different from the control group (P<0.01). However, the feed consumption and the feed-to-weight ratio increased; epimedium could promote the growth and development of female sheep, reduce feed consumption, but there was no significant statistical difference (P>0.05); epimedium could improve the live lambing rate, lambing rate, FSH and LH concentrations of female sheep to varying degrees. Among them, the 1.5% epimedium group was significantly different from the control group (P<0.05). The experiment showed that adding a certain proportion of epimedium could improve the reproductive performance of both male and female Small Tailed Han sheep, increase the feed consumption of male sheep but not increase the feed consumption of female sheep, and help improve immunity.
