呼伦贝尔草原黄羊体况的初步评价

对呼伦贝尔草原地区黄羊肾脏重量和肾脏中心脂肪指数的变化进行了研究。初步评价了不同年龄－性别组黄羊以及不同季节黄羊体况的差异。发现：黄羊左肾重量大于右肾，不同年龄－性别组黄羊间肾重存在极显的差异（P＜0．01），并且肾重与体重呈显的正相关性（P＜0．01）；黄羊肾重存在季节性差异，春季肾重大于秋、冬二季；KMFI值在不同的年龄－性别组间也呈明显的差异性（P＜0．01），KMFI值亦与体重吴正相关性（P＜0．01）；不同的季节，黄羊KMFI值差异明显（P＜0．01）。黄羊秋季体况最好，而冬末春初则较差。

A PRELIMINARY VALUE ON BODY CONDITION IN MONGOLIAN GAZELLE

The kidney weight and kidney midline fat index(KMFI) of Mongolian gazelle ,which were collected in Hulunbeier grassland in China from 1997 to 1998, were measured. A preliminary value on body condition of Mongolian gazelle was taken in different age-sex groups and in different seasons. The results show that the left kidney weight was heavier than the right kidneys. There was a significant different (F= 4.872, P<0.01) in the kidney weight among different age-sex groups. There was a significant positive relation between kidney weight and body weight (P<0.01). The kidney weight was changed in different seasons. In spring, the kidney weight was heavier than in autumn and in winter. A significant different (F=4.929,P<0.01) in the value of KMFI was found among age-sex groups. There also was a significant positive relation between KMFI value and body weight (P<0.01). In different seasons, there was a significant different (F=4.612,P<0.01) in KMFI value of Mongolian gazelle. In autumn, the body condition of Mongolian gazelle was the best, however, the body condition was worse in winter end and beginning spring.
