Abstract
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:the fineness 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 the fineness 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.关键词
