中文摘要:

      [目的]为进一步深入研究秦川牛遗传多样性及品种资源的保护与可持续利用性.[方法]本研究对秦川牛起源进行了初步调查.研究主要针对商代至唐代的牛种的形态学变化,从古代牛种的角、头部、颈部、鬐甲部、胸深、背部和股部七个方面的形态学特征的演化过程角度对秦川牛的起源进行探索.[结果]发现,由商代晚期至唐代中期的约两千年中,古代牛种的体质外貌明显向适于役用的方向进化,两汉时期是古牛种的重要转折期,[结论]从南北朝到唐代牛种逐渐演化出与现代秦川牛极为相似的特征.

英文摘要:

      To further the genetic diversity,preservation and sustainable utilization of Qinchuan cattle,the origin of Qinchuan Cattle were surveyed.Based on the morphological changes of Chinese cattle species from Shang Dynasty to Tang Dynasty and the morphological evolution of horn,head,neck,wither,chest depth,back and thigh,the evolution of Qinchuan Cattle were discussed.Preliminary study found that,from late Shang Dynasty to the middle Tang,about two thousand years,the ancient species of cattle evolved towards the ...
