摘要:

本研究从血液生理、生化指标水平探讨有角和无角牦牛群体的体况和代谢差异,为无角牦牛新品种的选育提供理论依据。试验检测了有角、无角牦牛群体的30项血液生理与生化指标,并用独立样本t检验对两个群体测得的各项指标进行了比较分析。结果表明,两群体间有11项指标差异极显著(P<0.01),5项指标差异显著(P<0.05),14项指标差异不显著(P>0.05)。从测定的数据初步判定,有角与无角牦牛群体在高原低氧适应性、肝脏代谢、肾脏代谢及骨质形成方面存在一定差异,无角牦牛比有角牦牛更适应高原低氧的环境。本试验结果可为牦牛品种资源的合理保护和利用以及新品种的选育提供科学依据。

Abstract:

The blood physiological and biological indexes were determined in both polled and horned yaks, to investigate the differences of body condition and metabolism between the two breeds, and provide a comprehensive understanding for new yak breeds. Thirty physiological and biochemical indexes of the polled and horned yaks were measured, and all these data were analyzed by independent-samples t test to compare the same index between the two groups. The results showed that there were extremely significant differences (P<0.01) in 11 indexes,5 indexes reached significant differences (P<0.05) and no significant differences (P>0.05) in 14 indexes between the polled and horned yaks. The results suggested that the polled yak was easier to adapt to the plateau hypoxia and there were many differences in adaptability of plateau hypoxia, kidney metabolism, liver metabolism and the growth and development of the bone between the polled and horned yak. This study could provide scientific basis for better protection and utilization of yak and the selection of the new yak breeds.
