退化草地放牧对绵羊增重的影响

The Impact of Degraded Grassland Grazing on Sheep Gain

对农村以放牧为主的养羊方式进行了调查。结果表明,在退化草地上放牧,处在生长发育期的东北细毛羊平均日增重在不同月份之间存在极显著差异,羊群的正常生长发育受阻。

The feeding of Dongbei fine wool sheep was investigated. The results showed that grazing in degraded grassland was the main feeding model, which influenced the sheep growth and development. Average daily gains have very significant difference among different stage and degraded grassland can not provide enough forages for sheep growth and development in most of the month of the year.
