摘要 目的:分析辽宁绒山羊年龄与绒毛生产性能的关系,指导绒山羊的养殖管理并提升绒毛生产性能。方法:从某饲养场中随机抽取80只辽宁绒山羊,年龄在1~8岁,对不同年龄段辽宁绒山羊对应的绒毛生产性能指标参数予以整理分析,探讨年龄与绒毛生产性能的关系。结果:绒山羊羊毛的细度随着年龄增加而增加,并在6岁时达到最高,然后逐步下降;从绒山羊羊毛产量随着年龄的增加而增加,其在5岁时达到最高,然后开始逐步下降。从绒山羊绒长方面分析,3、5岁绒山羊的绒长较大,其他年龄段绒山羊的绒长较小。结论:综合辽宁绒山羊绒毛生产性能的不同参数,4~5岁的辽宁绒山羊能够兼顾绒山羊羊毛的细度、羊毛产量以及绒长,建议辽宁绒山羊在养殖过程中可增加4~5岁年龄段羊的数量,保证绒毛生产性能处于最佳状态。 Objective:To analyze the relationship between age and wool production performance of Liaoning Cashmere goats,to guide the breeding management of Cashmere goats and improve the performance of cashmere production.Methods:80 Liaoning Cashmere goats,aged 1~8 years,were randomly selected from a feedlot.The indexes of wool production performance of Liaoning Cashmere goats in different age groups were analyzed,the relationship between age and wool production performance was studied.Results:thefineness of wool of cashmere goat increased with age,and reached the highest at 6 years old,then gradually decreased,it peaks at age 5 and then begins to decline.The cashmere length of 3-year-old and 5-year-old cashmere goats was larger than that of other age groups.Conclusion:according to the different production performance parameters of Liaoning Cashmere goats,Liaoning Cashmere goats aged 4~5 can take into account thefineness of wool,wool yield and cashmere length,it is suggested that Liaoning Cashmere goats can increase the number of 4~5 years old goats in the process of breeding,so as to ensure the best performance of Cashmere production.
