摘要
高寒气候区哺乳犊牛密闭牛舍内以小群体养殖为主.冬春季牛舍为了保温通风少,导致舍内有害气体浓度高,哺乳犊牛肺炎发病率居高不下.为解决该问题,引入犊牛岛,配套做好区域挡风墙、单排苫布覆盖,岛间麦秸填充、岛内麦秸铺垫等保温措施,哺乳犊牛可在-40℃15 天、-30℃以下70～90 天的高寒气候区健康生长,日增重1 000 g,肺炎发病率极低,为预防高寒气候区哺乳犊牛肺炎、保障其健康生长摸索出一条新路.
Abstract
In the alpine climate area,lactating calves are mainly bred in small groups.In order to keep warm and ventilation in winter and spring,it leads to high concentration of harmful gases in the houses and high incidence of pneumonia in lactating calves.To solve the problem,the introduction of calf island,form a complete set of regional windshield wall,single row tarpaulin covering,island straw filling,the island straw bedding insulation measures,lactation calves can be in-40℃15 days,30℃,70～90 days of cold climate zone healthy growth,gain 1 000 g,pneumonia incidence is very low to prevent cold climate area lactation calf pneumonia,guarantee its healthy growth for a new road.
