| 摘 要： | 在低磷地区以分组对比的试验方法 ,用不同含磷量的牧草在同等条件下喂饲两组低磷奶牛 ,定期采样分析 ,对各组奶牛血钙、血磷、超氧化物歧化酶 (SOD)、谷胱甘肽过氧化物酶 (GSH- Px)、丙二醛 (MDA)及牧草、土壤中磷含量、喂饲后奶牛生产性能等进行测定和观察。结果表明 :(1)在预试验期 ,对牧草施撒磷肥 ,收获后 ,土壤和牧草二者含磷量均明显提高。在其后的几年间再次测定该两项指标仍处于较高水平 (P<0 .0 5 ) ,后效应明显。 (2 )对低磷奶牛喂饲富磷牧草后 ,其血清磷由1.0 2 mm ol/ L提高到 2 .0 5 m mol/ L,两组差异极显著。 (3)对照组与试验组随着喂饲时间的延长 ,血清中抗氧化指标变化明显 ,试验组抗氧化能力增强 ,SOD、GSH- Px活性增强 ;MDA含量降低。(4)从对奶牛生产性能的测定看出 ,试验组生产性能有较大幅度地提高。

| Abstract: | The cows with low phosphorus in two groups were fed with different of phosphorus the same condition by dividing group and comparing. The samples were collected and analyzed, the output of milk were detected. The preventive effect of hypophosphatemia (hypophosphatemia?hemoglobinuria?osteomalacia) was studied. The aim of experiment is to treat and prevent the low phosphorus in cows from the source of food chain. The content of calcium,phosphorus,malonadehyde diethylacety (MDA), superoxidedase (SOD), glutathioneperoxidase (GSH Px) in serum, the content of phosphorus in soil and grass, the output of milk were detected respectively. The content of biochemical indexes in serum of trial group were different significantly compared with control group. So the treatment with adding the fetilizer of phosphorus in the source of food chain for low phosphorus areas was very important for the treatment and prevention of cows with low phosphorus. The results are follows: 1. It is fount that the trial area was lack of phosphorus through detected the content of phosphorus in grass?soil. The fertilizer of phosphorus were added to the experiment soil,and the content of phosphorus in soil?grass quality. 2. The content of phosphorus in serum after feeding grass with higher phosphorus to cows with low phosphorus was significantly (P<0.01), the content of serum calcium increased gradually. 3. The change of anti oxidant indexes was evident. The anti oxidant ability of trial group improved. 4.The ability of milking was increased according to measuring of milk yield. |
