| 摘 要： | 主要研究放牧制度对谢尔塔拉地区天然草地土壤物理性状以及对三河牛泌乳性能的影响。试验结果表明,不同放牧制度对土壤含水量、容重和孔隙度具有显著影响(p<0.05),其中轮牧区土壤含水量和容重均高于连牧区。放牧制度对泌乳量影响显著,轮牧区的产奶量提高了近25%(p<0.05),但放牧制度对乳脂率和乳蛋白含量影响不大(p>0.05)。

| Abstract: | The effects of the grazing system on physical characteristics of soil in Northern rangeland and milky property of Sanhe cow were mainly studied. The results showed that there existed the close relationship between physical characters of soil and precipitation, and the influences of grazing system on moisture content, unit weight, pore-solid degree of soil and milky production were notable(p<0.05), the moisture content and unit weight of soil under rotational grazing were higher than that under continuous grazing and milky production were increased by 25%; however, the difference of butterfat rate and the content of milky protein under two grazing systems were not notable. |
