| 摘 要： | 通过对集约化奶牛场的育成牛和泌乳牛各季节的粪产生量及粪样的分析测定,计算出两阶段的有机质产污系数,并对各个季节两阶段间差异进行比较分析。结果显示，集约化奶牛场四季度育成牛有机质产污系数平均为1 966.18 g/(头·d),四季度泌乳牛有机质产污系数平均为3 688.74 g/(头·d), 泌乳牛有机质产污系数远大于育成牛有机质产污系数。

| Abstract: | Through measuring the amounts and analyzing the components of feces of heifers and cows in the intensive dairy farm in four seasons, the organic matter pollutants producing coefficient (PPC) were calculated and compared between heifer and cow in all seasons. The results showed that the organic matter PPC of the heifer was 1 966.18 g·head－1·d－1, that of the cow was 3 688.74 g·head－1·d－1 in the intensive cow farm in the fourth season, the organic matter PPC of cow was much higher than that of heifer． |
