摘　　要：本研究是以放牧状态下宁夏中卫香山地区1~4岁的中卫母山羊体质量、体高、体长和胸围测定数据为研究对象,使用SPSS 8.0软件分析不同年龄对中卫母山羊各性状的影响。结果表明:放牧状态下,不同年龄对中卫母山羊的体质量、体高、体长和胸围影响显著(P<0.05),尤其对体质量影响极显著(P<0.01),体质量、体高、体长和胸围的变化随着年龄的增加而增加,在1~2岁时增速较快,2岁之后增速变慢。通过研究放牧状态下不同年龄对中卫山羊体尺体质量的影响,目的在于强化中卫山羊养殖户科学饲喂的意识,合理加强不同年龄阶段中卫母山羊的饲养管理水平,从而提高不同年龄阶段中卫母山羊的各项生产机能。In this study, the body weight, body height, body length and chest circumference of 1-4 year old Zhongwei goat ewes in Xiangshan area of Zhongwei, Ningxia were measured under grazing condition. SPSS 8.0 software was used to analyze the effects of different ages on various traits of Zhongwei goat ewes. The results showed that under grazing state, the body weight, body height,body length and chest circumference of Zhongwei goat ewes were significantly affected by different ages(P<0.05), especially the body weight was extremely significantly affected(P<0.01). The changes of body weight, body height, body length and chest circumference increased with the increase of age, and the growth rate was faster at 1~2 years old, but slowed down after 2 years old. By studying the effects of different ages on body size and weight of Zhongwei goats in grazing state, the aim is to strengthen the awareness of scientific feeding of Zhongwei goat farmers and reasonably strengthen the raising and management level of Zhongwei goat ewes at different ages, so as to improve the production function of Zhongwei goat ewes at different ages.
