摘　　要：选择‘河西绒山羊’5个胎次共100只,采集产后第30天、第100天的乳样,研究不同胎次和不同泌乳时间羊乳的营养成分及理化性质.结果表明:‘河西绒山羊’乳中粗蛋白含量第1、2、3胎均显著高于第4、5胎(P<0.05),乳中粗脂肪含量、总固形物含量第1、2、4胎均显著高于第5胎(P<0.05),第3胎显著高于第1、2、4胎(P<0.05),乳中非脂固形物含量第2、3胎均显著高于第1、4、5胎(P<0.05).乳粗蛋白含量、总固形物含量产后第30天显著低于产后第100天(P<0.05).乳酸度值第1、2、3胎均显著低于第4、5胎(P<0.05),产后第30天乳酸度值显著低于产后第100天(P<0.05).One hundrede ‘Hexi cashmare goat’in 5 parities were selected to collect milk samples,con-taining 30th day＆#39;s milk and 100th day＆#39;s milk,the milk nutritional components and physic-chemical proper-ties were studied on different parity and different lactation time.The results showed that the contents of milk protein of 1st,2nd,3rd parity was separately higher than that of 4th,5th parity significantly （P〈0.05）.The contents of milk fat,total solids of 1st,2nd,4th parity was separately higher than that of 5th parity significantly （P〈0.05）,the 3rd parity was higher than that of 1st,2nd,4th parity significantly （P〈0.05）.The contents of milk non-fat solids of 2nd,3rd parity was separately higher than that of 1st,4th,5th parity significantly （P〈0.05）.The contents of milk protein,total solids of 30th day were lower than that of 100th day significantly （P〈0.05）.Physic-chemical properties,the milk acidity of 1st,2nd,3rd parity was separately lower than that of 4th,5th parity significantly （P〈0.05）,the milk acidity of 30th day was lower than that of 100th day significantly （P〈0.05）.
