2不同牛舍地面设计对奶牛的影响显示文摘高产奶牛几乎全年或是整个生产周期都是在畜舍内度过。非放牧条件下(如散栏饲养),多种因素(磨损、创伤、体重和微生物)会影响奶牛的蹄部(站立的时候)和腿部(躺卧的时候)健康。尤其是奶牛在生活环境较差时不愿意走动,以免发生危险。躺卧区域对奶牛来说最为重要,通道地面的质量还是会对奶牛行为产生很大影响,因为奶牛要四处走动进行社交活动,还要采食和挤奶。为了给奶牛的休息、站立和行走提供合适的地面,牛舍需要配备柔软的地面,同时要有足够的摩擦力(防止牛蹄过度生长或避免过度损伤),并保证地面的干燥和清洁。管理者应关注牛舍地面的卫生状况和管理水平,注意可能引起奶牛肢蹄损伤的危险区域,尽量减少奶牛行走在坚硬、不卫生及易损伤肢蹄的地面上,要保证每头牛有一个舒适的卧床。应减少奶牛挤奶等候的时间,并保证奶牛24h都能觅食。从长远的投资收益而言,牛舍建造应考虑使用柔软有弹性、质量好的橡胶垫,牛舍地面要有一定倾斜度,保证尿液及时通过管道排出,最好使用橡胶漏缝地板,同时配备刮粪板,最好在采食通道上铺设橡胶垫,并建设坚固的排水管道及排污系统。Christer Bergsten 黄鸿威 宋扬 马佳莹 曹志军 2015中国奶牛2015,,11:4
