气候变化对太行黑山羊养殖业发展的影响分析

The Impact of Climate Change on Taihang Black Goat Breeding Development

太行黑山羊是我国黑山羊资源基因"宝库"中的一颗耀眼明珠,对饲养环境有较强的适应性。分析晋城市近40年来气候变化特征,研究其对太行黑山羊养殖业发展的影响,结果表明:晋城市年平均气温呈明显上升趋势,年降水量随时间推移变化不大,无霜期延长,对太行黑山羊繁殖性能和羔羊生产性能有显著提高,冬季气温升高更有利于羊只受胎、繁殖;随着气温逐年升高,积温增加,无霜期延长,饲草返青期提前,黄枯期推迟,丰草期延长,为太行黑山羊饲养提供丰富的饲草资源。对今后太行黑山羊养殖业发展具有一定的参考价值。

Taihang black goat is a dazzling pearl in the black goat genetic resources treasury,which has strong adaptability to the feeding environment.The characteristics of climate change in Jincheng City in recent 40 years were analyzed to study the impact of climate change on Taihang black goat.The results showed that in Jincheng City, the annual average temperature showed a clear upward trend, annual precipitation changes not too much with the changing of time ,frost free period extended ,which improved the Taihang black goat reproductive performance and lamb production performance.Winter warming was more advantageous to the sheep fertilization,reproduction.The temperature rising,accumulated temperature increasing, frost free period extending, forage grass turning green period in advance, withered period delaying, grass rich period prolonging, provided abundant forage resources for the Taihang black goat breeding.This paper has certain reference value on the future Taihang black goat breeding development.
