摘要： 旨在揭示陕北白绒山羊的生长发育规律，为其选育和科学的饲养管理提供参考依据。选取日龄相近的39只陕北白绒山羊（公羊16只，母羊23只）分别测量其体重和体尺指标。结果表明：（1）陕北白绒山羊体重和体尺各项指标累积生长均随月龄增加呈上升趋势。（2）陕北白绒山羊绝对增重和相对增重在出生后至1月龄最大，在3月龄降至最低值，随后分别在5月龄、8月龄出现两个绝对增重高峰期，而相对增重呈现出平稳变化趋势。（3）陕北白绒山羊公羊体高绝对生长值在8月龄最高，母羊体高绝对生长值在9月龄最高，而公母羊体高相对生长值也分别在8月龄和9月龄最高。公母羊体长绝对生长值均在9月龄最高，体长相对生长值均在4月龄最高，胸围绝对生长值和相对生长值均在5月龄最高，管围绝对生长值和相对生长值均在12月龄最高。综上，陕北白绒山羊在出生后1月龄内、4~5月龄和7~8月龄增重速度较快。体尺指标在4~5月龄和7~9月龄增速较快。在此期间应注意营养提供，从而充分满足其生长发育的营养需要。

Abstract: The purpose of this study was to reveal the regulation of growth and development in Shanbei white cashmere goats, and provide reference for variety selection and breeding management. 16 males and 23 females, similar birth date were selected to measure weight and body measurement index. The results showed as follows:(1)the weight and body measurement index cumulative growth of the Shanbei White Cashmere Goats increased with ages. (2)Absolute weight gain and relative weight gain were the highest within 1 months of age, two indexes declined minimum value during 3 months of age. Then two peak of absolute weight gain appeared in 5 months of age and 8 months of age, however, relative weight gain showed stable change trend. (3)Absolute growth rate of body height of rams was the highest in 8 months of age, and absolute growth rate of body height of ewes was the highest in 9 months of age. Relative growth rate of body height of rams and ewes were the highest in 8 months of age and 9 months of age, respectively. Absolute growth rate of body length was the highest in 9 months of age, and relative growth rate of body length was the highest in 4 months of age. Absolute growth rate and relative growth rate of chest girth were the highest in 5 months of age. Absolute growth rate and relative growth rate of cannon circumference were the highest in 12 months of age. [Conclusion]In conclusion, weight gain rate of the Shanbei White Cashmere Goats was fast within 1 months of age, 4~5 months of age and 7~8 months of age. And growth speed of body measurement index was fast in 4~5 months of age and 7~9 months of age. So enough nutrition should be provided at these ages in order to meeting the nutritional needs of growth and development in Shanbei White Cashmere Goats.
