| 摘 要： | 在中国农业大学沽源草地试验站研究了两种放牧制度与放牧强度对在多年生禾草/紫花苜蓿混播人工草地上放牧奶牛血液生化指标的影响。结果表明:放牧促进了奶牛营养状况的改善,血清中游离脂肪酸和尿素氮含量明显降低,而Ca、P、血糖、甘油三酯、碱性磷酸酶、总蛋白和白蛋白等含量则均有所提高,不同放牧处理对奶牛血液代谢有一定的影响,轻度轮牧对奶牛机体代谢的促进作用高于中度轮牧和连续放牧。

| Abstract: | The effect of two grazing systems and two grazing intensities on the blood biochemical index of dairy cows grazed in mixed sward of alfalfa-grass were studied at Guyuan Grassland Research Station of China Agriculture University in Hebei province.The result showed that blood metabolites of Cow were improved after grazing.The lower serum urea concentrations and non-esterified fatty acids and higher glucose,calcium,phosphorus,triglycerides, protein and albumin concentrations were observed at the end of grazing season,and the increment in light rotational grazing treatment was higher than other treatments. |
