暗腹雪鸡与海兰褐鸡血液生理生化指标的比较

Physiological and Biochemical Blood Indices:A Comparison between Tetraogallus himalayensis and Hyline Variety Brown Chicken

为了解暗腹雪鸡(Tetraogallus himalayensis)正常血液生理生化特性,本文对暗腹雪鸡21项血液生理生化指标进行了测定,并与海兰褐鸡(Gallus gallus domesticus var.Hyline)进行了比较。测定结果,暗腹雪鸡的红细胞纵径及横纵径乘积、平均红细胞容积及平均红细胞血红蛋白含量极显著大于海兰褐鸡(P<0.01);暗腹雪鸡天冬氨酸氨基转移酶和胆固醇含量均极显著高于海兰褐鸡(P<0.01)。其他各项血液生理生化指标两禽种间之间差异不显著。实验结果表明,暗腹雪鸡血液生理生化指标与家养蛋鸡之间有一定差异,暗腹雪鸡对高原低氧环境有较强的适应性可能与其红细胞体积较大、平均红细胞容积及平均红细胞血红蛋白含量较高有一定关系。

To get better insight of the very unique physiological and biochemical features of TetraogaUus himalayensis, twenty-one blood parameters were tested and then compared with those of Hyline Variety Brown Chicken（ Gallus gallus domesticus var. Hyline ）. Results showed that the size of red blood cell in T. himalayensis was different from that of Hyline Variety Brown Chicken, with the longitudinal diameter and the value of the longitudinal diameter x transverse diameter larger than those of the latter （P 〈 0. 01 ）. The MCV and MCH in T. himalayensis were extremely bigger （ P 〈 0. 001 ） , while the AST and the serum CHO in T. himalayensis were significantly higher than that in Hyline Variety Brown Chicken （ P 〈 0. 01 ）. The rest physiological and biochemical parameters measured were not different between these two birds. It is suggested that there are some differences between the two birds in terms of blood physiology and biochemistry. The adaptability of T. himalayensis to plateau hypoxemia may be partly related to the bigger size of red blood cells, as well as higher MCV and MCH.
