摘要
通过对集约化奶牛场的育成牛和泌乳牛各季节的粪尿产生量进行测定,并且分析粪样和尿样,从而计算出育成牛和泌乳牛的铜产污系数,并比较两者各季节间的差异性。结果显示集约化奶牛场的育成牛铜产污系数4个季节平均为0.14g/(head.d),泌乳牛铜产污系数4个季节平均为0.31g/(head.d),泌乳牛铜产污系数远大于育成牛铜产污系数。
Through measuring the amounts and analyzing the components of faeces and urine of heifers and cows in the intensive dairy farm in four seasons,Cu pollutant-producing coefficients were calculated and compared between heifer and cow in all the seasons.The results showed that the Cu pollutant-producing coefficient of the heifer was 0.14 g/（head·d）,that of the cow was 0.31 g/（head·d） in the intensive dairy farm in the four seasons.The Cu pollutant producing coefficient of cow was much higher than that of heifer.
