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.
Abstract
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 scarcity of grass re-sources in these areas and the reliance on high-concentrate feeds for calves have increased breeding costs and de-teriorated meat quality and flavor.Five high-quality grass species,red clover(Trifolium pratense),Sudan grass(Sorghum sudanense),Russian wildrye(Psathyrostachys juncea),Gannong no.1 alfalfa,and black pasturage,were planted at an altitude of more than 3,300 meters.The study observed the cutting growth rate,nutrient compo-sition,and weight gain in yak calves.By adding different proportions of locally grown high-quality forage to yak calf diets,the best forage for calf breeding was identified,providing a scientific basis for the high-quality develop-ment of the industry.
