高原型藏羊多胎繁殖技术

Breeding Techniques of Plateau Tibetan Sheep with Multiple Births

高原型藏羊作为藏羊的主要品种,主要分布于我国西北地区的青海省。高原型藏羊存在多胎繁殖的现象,但概率较低。为进一步了解有关青海高原型藏羊的多胎繁殖的现象及其发展趋势,试验通过从青海省的地理环境及气候特点等方面入手,利用青海省刚察县农牧科技示范牧场的高原型藏羊作为试验羊群,通过对试验羊群进行多胎繁殖技术处理后,对其产下的羊羔进行科学饲养及定期观察后,与普通的高原型藏羊做对比,对高原型藏羊的多胎繁殖技术进行初步分析。

Tibetan sheep of plateau type,as the main breed of Tibetan sheep,are mainly distributed in Qinghai province of northwest China.Tibetan sheep of plateau type have the phenomenon of multiple births,but the probability is low.In order to further understand the phenomenon and development trend of prolificacy of Tibetan sheep in Qinghai plateau,the experiment started from the geographical environment and climatic characteristics of Qinghai Province,the plateau type Tibetan sheep in the demonstration pasture of agricultural science and technology in Gangcha county of Qinghai province was used as the experimental sheep group.After the experimental sheep were treated with the technique of multiple-birth reproduction,the lambs produced by the experimental sheep group were raised scientifically and observed regularly,compared with common plateau Tibetan sheep,the prolificacy of Plateau Tibetan sheep was analyzed.
