| 摘 要： | 为比较分析内蒙古二郎山绒山羊与蒙古国棕色绒山羊主要生产性能的差异,每个品种选取60只绒山羊进行生产性能测定,并利用SAS软件和Excel进行统计分析。结果表明,二郎山绒山羊平均体斜长、胸围及产绒量极显著高于蒙古国棕色绒山羊（P〈0.01）,在平均绒细度和体重上,二郎山绒山羊显著高于蒙古国棕色绒山羊（P〈0.05）;2个品种绒山羊体高、体斜长、胸围与体重相关关系极显著（P〈0.01）,相关关系最大的是胸围;2个品种绒细度与产绒量之间呈正相关,但不显著（P〉0.05）,二郎山绒山羊绒长度与产绒量相关关系极显著（P〈0.01）。另外,2个品种绒山羊的体高、体斜长与绒长度之间存在负相关;蒙古国棕色绒山羊的胸围与绒长度之间也存在负相关。综合性能上,二郎山绒山羊品种优势比蒙古国棕色绒山羊明显。

Comparative Analysis of the Main Production Performance between Chinese and Mongolian Cashmere Goat |
| |
| Abstract: | In order to compare the differences of main production performance between Inner Mongolia Erlangshan cashmere goat and Mongolia Brown cashmere goat, sixty cashmere goats for each variety were selected and their main production performance were determined and statistically analyzed. The results revealed that the body slanting length, chest circumference and cashmere yield of Erlangshan cashmere goat were very significantly higher than those of Mongolia Brown cashmere goat（P〈0.01）, and the cashmere fibre diameter and body weight of Erlangshan cashmere goat were significantly higher than those of Mongolia Brown cashmere goat（P〈0.05）; there were very significant correlation between height at withers, body slanting length, chest circumference and body weight in both varieties（P〈0.01）, and the highest correlation value was observed in chest circumference;while there was a positive correlation between cashmere fibre diameter and cashmere yield in both varieties, no statistical significances were observed（P〈0.05）; very significant correlation between cashmere fibre length and cashmere yield in Erlangshan cashmere goat was found（P〈0.01）; there was a negative correlation between height at withers, body slanting length and cashmere fibre length in both varieties; a negative correlation between chest circumference and cashmere fibre length in Mongolia Brown cashmere goat was also observed. It was demonstrated that the comprehensive production performance of Inner Mongolia Erlangshan cashmere goat is superior to that of Mongolia Brown cashmere goat. |
