天祝白牦牛种群品质保护探索

Exploration of Tianzhu White Yak Population Quality Protection

舍饲育肥是解决草畜矛盾的有效途径,然而,舍饲育肥限制了动物的活动,使脂肪沉积增加,降低肉的品质;环境的安逸影响了动物的体质,降低了抗病能力、抗寒能力和在自然环境下的某些特有品质,如绒毛的质量和数量下降;饲料的相对单一和适口性,影响了肉的品质和风味,降低了动物的耐粗饲性。因此,我们探索出了以补饲、游牧、轮牧结合短期育肥,解决世界珍稀物种天祝白牦牛与牧草的矛盾。

Fast fattening is an effective way to solve the conflicts between animals and grass. However, fast fattening re- stricts animal activity,which increased fat deposition, reduced meat quality. The comfortable environment affects the animal＇s constitution ,lowers its resistance to disease and cold, which reduces some qualities in the natural environment,such as the quali- ty and quantity of the villi. The relative singleness and palatability of feed affect the quality and flavor of meat and decrease the tolerance to coarse feed of animals. Therefore,we explored a short--term fattening model combined feeding, nomadic and graz- ing to solve the contradiction between Tianzhu White Yak and grass.
