贵州高原人工草地上的绵羊放牧越冬试验

OVERWINTERING OF SHEEP GRAZED ON SOWN PASTURES AT GUIZHOU PLATEAU

本文研究了绵羊在贵州高原人工草地上的放牧越冬情况,试验结果表明,杂种绵羊冬春季节在足够的优质豆科、禾本科混播人工草地上,进行纯放牧,其体重、羊毛细度均未发生明显变化,证明在这种条件下可以安全越冬;亦说明大力发展人工草地是发展养羊业的重要措施。

This paper reported the overwintering of sheep grazed on sown pastures at Guizhou Plateau. The results showed that the body weight and wool fineness of hybrid sheep did not decrease significantly during the whole winter and spring under the conditions of full grazing (no supplementary feeding and shed) on established grass-clover pasture, which demonstrated that the sheep can overwinter safely under the experimental conditions, and that establishing high quality sown pasture is an important way for developing sheep production.
