西藏山羊(川西型)产绒量的通径分析

A PATH ANALYSIS OF CASHMERE YIELD IN TIBETAT GOATS (WESTERN SICHUAN TYPE)

对川西型西藏山羊的产绒量和若干体尺性状、绒毛品质性状之间的关系作了通径分析。结果表明,绒毛伸直长度、体重、胸围是影响产绒量的主要因素。对通径系数作显著性检验,不显著者逐一剔除,给出了能预测产绒量的最佳回归方程。

The Tibetan goat is an old breed, it is famous for its quality of undercoat known as cashmere, A path analysis of influence of some traits on cashmere yield was made. The results indicated that the body weight, the stretched down length and the heart girth were the most important factors affecting the yield. A best regressive equation that can calculate the cashmere yield was given.
