| 摘 要： | 【目的】观测小尾寒羊在广东湛江地区的生长发育和繁殖性能，为推动小尾寒羊在亚热带地区的发展提供理论依据。【方法】采用对比方法分析小尾寒羊原产区（山东济宁市）与引入地（广东湛江市）生态、饲养条件及小尾寒羊生长发育、繁育性能等指标的差异。【结果】广东湛江地区气候炎热、潮湿，但饲料资源明显优于小尾寒羊原产区。引入湛江地区的小尾寒羊生长速度与原产区基本相同，具有较高的遗传稳定性，只要能满足其营养需要，就能发挥出良好的生产性能。小尾寒羊在广东湛江地区继续保持了原产区常年发情、性成熟早、多胎、繁殖力高的优良特性，可达到一年两胎或两年三胎。【结论】在亚热带地区推广小尾寒羊养殖是可行的。

| Abstract: | 【Objective】The growth characters and reproductive performances of Small-tail Han Sheep in Zhanjiang area were studied to provide theoretical references for breeding Small-tail Han Sheep in subtropical area. 【Method】The differences of the ecological and raising conditions, the growth and breeding of Small-tail Han Sheep performances between the native area （Jining, Shandong） and the introduced area（Zhanjiang, Guangdong） were compared. 【Result】The high temperature and humid climate conditions of Zhanjiang area were significantly different from Jining area, but the abundant forage resource of the introduced area was an obvious advantage. The Small-tail Han Sheep can adapt to high temperature and humid climate conditions of Zhanjiang. No significant differences of the production performance were seen between Zhanjiang and the native region. The high growth rate and genetic stability of the Small-tail Han Sheep in Zhanjiang were almost the same with the native area. The advantages including perennial oestrus, early sexual maturity, litter-bearing, and high fecundity （two or three fetus per year） of the introduced sheep were well preserved. 【Conclusion】It can be inferred that raising Small-tail Han Sheep in the subtropical area is feasible. |
