| 摘 要： | 目的]探究主要非遗传因素对南疆绒山羊主要性状的影响。方法]利用SAS 8.1软件的GLM程序,分析性别和年度对产绒量、初生重、断乳重、绒纤维直径以及绒纤维直径离散的影响。结果]性别、年度对产绒量、断乳重、绒纤维直径以及绒纤维直径离散都有极显著的影响(P<0.01);年度对初生重有显著的影响(P<0.05);性别和年度对初生重、绒纤维直径离散影响不显著(P>0.05),对产绒量、断乳重和绒纤维直径影响极显著(P<0.01)。结论]在估计南疆绒山羊遗传参数和育种值时,对以上5个性状有显著影响的因素可以作为固定效应放到模型中。 |

Analysis of Non-genetic Factors of Southern Xinjiang Cashmere Goats Primary Traits |
|
| Abstract: | 【Objective】The objective of this study was to investigate the effect of main non-genetic factors on five traits in Nanjiang cashmere goats.【Method】The effect of main non-genetic factors(including gender and year) on cashmere yield,birth weight,weaning weight,cashmere fiber diameter and cashmere fiber diameter discrete was analyzed by least squares means with SAS 8.1 program.【Result】The results showed that the effect of gender,year has a highly significant effect on cashmere yield,weaning weight, cashmere fiber diameter and cashmere fiber diameter discrete(P<0.01);The effect of year has a significant effect on birth weight(P<0.05);The effect of gender and year has no significant effect on birth weight, cashmere fiber diameter discrete(P>0.05),and has significant effect on cashmere yield,weaning weight and cashmere fiber diameter(P<0.01).【Conclusion】The five traits significantly influence factors can be used as fixed effects in the model when estimating genetic parameters and predicting breeding value of Nanjiang Cashmere Goat. |
