19泌乳奶牛热应激管理显示文摘奶牛的体型庞大,所以对热量更加敏感。因为5℃-20℃是奶牛的适应温度,运输途中恒温器温度应设置为13℃。那么,如何发挥它的最大产奶性能,这对奶牛生产者是一个很大的挑战。上图展示的是2008-2017年美国奶牛平均产奶量的情况。从图中可看出,在过去十年里美国奶牛平均产奶量增长了12%。在提高奶牛单产量的同时,产热也在增加,相比1950年,奶牛产热平均增长了30兆焦/每天或28000英热单位/每天。Robert J. Collier 2019今日畜牧兽医(奶牛)2019,0,6:0
20高产奶牛饲喂策略显示文摘营养是影响动物生产性能、健康和福利最重要的因素,高产奶牛需要特别的营养搭配,尤其是应激阶段。良好的饲养管理可以改善牧场经济效益。养牛的最终目标是把饲料高效地转化为牛奶,为了使奶牛消化系统更有效,需确保瘤胃微生物生长的适宜环境,可以通过平衡奶牛不同生理阶段的营养使奶牛达到高产。想要做好高产奶牛饲养工作,需要做到以下几方面:采食量最大化;适宜营养参数;适宜的能量(碳水化合物和脂肪)、蛋白、微量元素和维生素;监测日粮组成(常规粗饲料、饲料分析);收割和购买高质量粗饲料,并且合理搭配。Robert J. Collier 2017今日畜牧兽医(奶牛)2017,0,1:0
