    湖羊和川中黑山羊在华南地区适应性研究

    Study on adaptabilities of Hu sheep and Chuanzhong black goat in Southern China

      摘要
    • 摘要:
      目的 研究山羊和绵羊引进品种在华南地区适应性问题。
      方法 以外省引进的湖羊及川中黑山羊为研究对象，统计分析湖羊和川中黑山羊生长、繁殖性能的变化，及与环境温湿度的关系。
      结果 湖羊和川中黑山羊在引种到华南地区的1年内，其部分生长、繁殖性能有不同程度的下降(P < 0.01)，湖羊的产羔率与环境温度、湿度显著相关(P < 0.05)，湖羊和川中黑山羊的羔羊死亡率与温度显著相关(P < 0.05)。
      结论 从外省引进的湖羊及川中黑山羊在华南地区饲养，短期内会出现一定的适应性问题，湖羊母羊的繁殖率容易受到高温高湿天气的影响，而川中黑山羊羔羊的当月死亡率在华南地区的冬季会明显上升，因此在管理上要注意湖羊夏季防暑及川中黑山羊的冬季羔羊保温。

       

      Abstract:
      Objective In order to study the adaptabilities of introduced varieties of sheep and goot in Southern China.
      Method Hu sheep and Chuanzhong black goats were introduced from other provinces into Southern China. Their growth and reproduction performances and the relationship between growth, reproduction performances and ambient temperature and humidity were statistically analyzed.
      Result Within one year of introduction, certain growth and reproduction performances of Hu sheep and Chuanzhong black goats declined in different degrees (P < 0.01). Lambing percentage of Hu sheep was significantly correlated with ambient temperature and humidity (P < 0.05), and the mortality rates of Hu sheep and Chuanzhong black goats were significantly correlated with temperature(P < 0.05).
      Conclusion There are adaptation problems of Hu sheep and Chuanzhong black goats within short period of introduction into Southern China from other provinces. The reproduction rate of female Hu sheep is negatively affected by the high temperature and humidity climate, and the monthly mortality rate of Chuanzhong black goat lambs largely rises in winter. Therefore, we should pay attention to the heatstroke prevention of Hu sheep in summer and heat preservation of Chuanzhong black goats in winter during management.
