Study on Estimation of Genetic Parameters of Economic Traits of White Cashmere Goats in Inner Mongolia
摘要
Abstract
The genetic parameters of the economic traits of white cashmere goats in Inner Mongolia were estimated by using BLUP (Best linear Unbiased Prediction) and AIREMAL (AI Restricted Maximum Likelihood) methods. The results showed that the herita-bilities of cashmere yield, cashmere thickness, body weight after fleecing, hair length, hair fineness, velvet length, velvet fineness and the ratio of velvet length to velvet fineness were 0.2807, 0.1092, 0.2751, 0.2237, 0.2122, 0.2245, 0.2373 and 0.2218, respectively , and all belonged to the moderate heritability. The cashmere yield had obvious positive genetic correlation with the cashmere thickness and the ratio of velvet length to velvet fineness, and their genetic correlation coefficients were 0.5915 and 0.4277, respectively. The cashmere yield had obvious positive phenotypic correlation with the cashmere thickness and body weight after fleecing, and their phenotypic correlation coefficients were 0.6095 and 0.4970, respectively.关键词
