青海藏獒体尺与毛特性的相关性分析

Qinghai Tibetan Mastiff Body Measurements and Hair Characteristics of Correlation Analysis

对青海省玉树州称多县、杂多县、囊谦县、果洛州玛多县、达日县及甘德县共100只藏獒（♀55只、♂45只）的体尺、毛特性进行了研究,并对各项指标进行了相关性分析。结果表明：（1）青海藏獒体尺指标中,在性别组间除胸围指标外,其余各指标间差异显著（P〈0.05）。（2）成年公藏獒的产毛量、粗毛长度、细毛厚度、粗毛伸直长度比母獒高,差异极显著（P〈0.01）。（3）无论是公藏獒还是母藏獒,其体重与产毛量、体尺间均呈极显著正相关,其中体重、体高、体长、胸围、管围与产毛量间相关系数在0.820 1~0.858 4之间。（4）青海藏獒产毛量与毛特性指标间,与粗毛长度、细毛厚度以及粗毛伸直长度间有极显著的正相关性（P〈0.01）,而毛特性指标间除粗毛细度与绒毛细度呈较强的负相关外,其余指标间均呈正相关,但相关性强度不一。

The Yushu prefecture in Qinghai province said county,heteropoly county,capsule modest,go luo state,madoi county,and the gander county 100 Tibetan mastiff（ ♀55,♂45） body measurements,wool characteristics are studied,and correlation analysis of the indicators. The results showed that：（ 1） Index of qinghai Tibetan mastiff body measurements,except chest index between the gender group,the rest of the difference between each index significantly（ P〈0. 05）.（ 2） Adult male Tibetan mastiff mastiff produced wool quantity,coarse hair length and thickness of fuzz,coarse contour length is higher than female Tibetan mastiff,extremely significant difference（ P〈0. 01）.（ 3） Whether male Tibetan mastiff or female Tibetan mastiff,its weight and produce wool quantity,are significantly positive correlation between body measurements,including body weight,body height,body length,chest circumference,tube is surrounded with wool quantity between the correlation coefficient between 0. 820 1 ~ 0. 858 4.（ 4） Made in Qinghai Tibetan mastiff,between fur and fur property index and coarse hair length and thickness of fuzz and coarse contour length has a significant positive correlation between（ P〈0. 01）,and in addition to shag fineness between fur property index and strong negative correlated to the wool fineness,there was a positive correlation between the indicators,but the correlation of different strength.
