北方寒区散栏育肥牛舍配套工艺及环境评价

Matching Technology and Environmental Assessment of Free Stall Barn Fattening Cowshed in Northern Cold Regions

[目的]为了发挥肉牛在北方冬季环境条件下其最佳生产潜力。[方法]设计了散栏保温牛舍和开放式散栏牛舍2种类型畜舍形式,分别在牛舍中心距离地面0.5m和1.5m处进行温度、湿度测定。[结果]舍内平均湿度为100%,最低温度为-0.6℃,育肥牛平均日增重达到0.83kg/头。[结论]散栏式牛舍冬季湿度大、温度低,牛只采食自由性较大,可改为采用颈杠式,固定床位,设有分隔栏方式,减少温湿度蒸发,同时可避免争食现象。

[Objective]To achieve the best production potential of beef cattle under the northern winter environmental conditions [Method] This paper designed free two types of barn, insulation stall barn and open free stall barn,and measured the temperature and humidity at the center of the barn 0. 5 m and 1.5 m from the ground. [Results] Average of humidity was 100%. The lowest temperature was 0.6 ℃. The average daily gain of fattening cattle was 0.83 kg per head. [Conclusion]Stall barn high humidity, and low temperature in winter, greater freedom cattle feed,could be changed using the neck bars mode, fixed beds,as well as they would be divided fences to reduce the evaporation temperature and humidity and could avoid contenting food phenomenon at the same time.
