摘　　要：选取健康奶牛10头,按胎次、年龄相同或相似的原则,分为高产奶量组和低产奶量组.两组日粮组成相同,同一时间采集血液,测定血浆内毒素含量,进行对比.结果表明,高产组奶牛血浆内毒素极显著高于低产组奶牛;高产组奶牛更容易发生由于血浆内毒素过高所引起的各种疾病,使高产奶牛产奶寿命降低.Ten healthy cows were singled out and divided into two groups—high yield milk group and low yield milk group according to the principle of the order of the embryos and the same or similar age.The two groups had same food and then their blood was collected at the same time to measure how much poison in the plasma so that the comparison could be made.The result shows that the poison in the plasma of the high yield cows is obviously higher than that of the low yield cows.That means the high yield cows are more likely to fall ill because of the higher poison in their plasma,which makes them live a shorter life.
