摘要
首次采用生态地理比较分析法,根据云南黄牛类群分布的自然环境特点,研究了云南黄牛形成与分布的自然生态规律,以及云南黄牛体形结构(体尺、体重、体型结构)、内部结构特征(体温、呼吸、脉博、血液指标,心脏和肺)和肉用性能(屠宰率、净肉率、眼肌面积)与生态因子(海拔、气温、降雨量、植被状况等)的相关规律。
In this paper,the ecological law of the distribution of Yunnan Yellow cattle,and the interrelation regularity among the body features of Yunnan Yellow cattle (the boy measurement,the weight, the body shape,the rectul temperature,the respiratory rate,the cardiac rate,the blood contents of Hb,red cells and white cells,the weights of lung and heart,and the meat performance),altitud,temperture,rainfalls,types of grassland and vegetation conditions have been studied on the basis of the natural enviroment features of the distribution of the Yunnan Yellow cattle and the breed characteristics of Zebu,Diqin yellow cattle,Zhaotong yellow cattle,Wenshang yellow cattle and Gayal.
