中文摘要:

      本试验旨在试验研究适宜高寒牧区的优质牧草及对牦犊牛培育的影响，随着草原畜牧业的转型升级，为此筛选适宜高寒牧区的优质牧草至为重要，加之高寒牧区草资源匮乏，高精料饲喂犊牛，使养殖成本增加，肉品质及肉品风味变劣。在海拔3300米以上种植红豆草、高丹草、俄罗斯燕麦草、苜蓿工农1号、黑牧草冬牧等等5个优质草种，观测其刈割生长速度、营养成分、犊牛增重等效果。给牦犊牛日粮中添加不同比例本地种植优质牧草，观测其培育牦犊牛增重效果，筛选出牦犊牛培育的最佳优质牧草，为产业高质量发展提供科学理论依据。

英文摘要:

      the purpose of this experiment is to study the quality forage suitable for alpine pastoral area and its effect on the breeding of yak calves. With the transformation and upgrading of grassland animal husbandry, it is very important to select the quality forage suitable for alpine pastoral area, in addition, the lack of grass resources in alpine pastoral area, high-concentrate feed calves, raising costs increased, meat quality and meat flavor deterioration. At an altitude of more than 3,300 meters, five high-quality grass species, Vigna angustifolia, Oryza sativa, Gannong no. 1 alfalfa, and black pasturage, were planted at an altitude of more than 3,300 meters, the effects of cutting growth rate, nutrient composition and calves weight gain were observed. The effects of adding different proportion of locally planted high quality forage to yak calves diet were observed, and the best high quality forage for yak calves was selected, which provided scientific basis for high quality development of industry.
