| 摘 要： | 波尔山羊为季节性多次发情品种 ,产羔率较低 ,但肉用性能好 ,与国内多个品种杂种对生长速度和肉用性能有良好的杂种优势。为了提高肉羊生产经济效益 ,提高波尔羊繁殖效率具有重要意义。季节、光照和温度以及饲养管理等因素对波尔羊繁殖力有影响。加强选育和饲养管理 ,诱导青年羊发情排卵 ,缩短成年羊产羔间隔 ,提高窝产羔数 ,合理应用胚胎移植技术 ,提高公羊性欲和精液品质及保存效果等 ,均可提高波尔羊的繁殖力。

| Abstract: | The Boer goat is a seasonly multiestrous breed with lower lambing rate, better merit of meat production, and faster growth and better hetetosis for its crossbreed with indigenous goat breeds, compared with indigenous breeds in China. Improvement of reproductive efficiency takes important role in increase of economic benefit of goat production. Reproductive efficiency which is affected by season, lighting, ambient temperature, nutrition and management can be improved by measurements such as suitable feeding, induction of puberty, shortening lambing interval, increasing lambing rate, application of embryo transfer, improving libido and semen quality and storage effect. |
