环境因素对羊繁殖性能影响的研究

Effects of Environmental Factors on the Reproduction Performance of Sheep

在现代化的养羊业中,环境因素对羊的繁殖等生产性能造成的影响不可忽视,高温对羊性细胞生成、受精卵发育、内分泌和妊娠等方面危害性最大,其他因素也不容小觑。文章从空气温度、湿度对母羊发情受胎和公羊精子品质的影响,光照对母羊发情排卵及其他生殖激素的影响,饲养密度对羊繁殖性能的影响以及空气中有害气体对羊的危害和防治措施等方面进行简要介绍,以期在生产中改善环境条件,提高羊的繁殖效率。

In the modern sheep-raising industry, environmental factors affect the production performance of the sheep, such as reproduction. High temperature also poses threat on the production of ovine cells, fertilized eggs, endocrine and pregnancy. Other factors also cannot be underestimated. This article examined the effect of temperature and moisture on the estrus of the ewes, the impact on the sperm quality of the ram, the effect of light on ovulation and other reproductive hormones in the ovine estrus, the effect of rearing density on the reproductive performance of the sheep, and the harmful gases in the air to the sheep. The hazards and prevention and control measures were briefly introduced to improve the impact of environmental factors in production, thereby increasing its reproductive efficiency.
