| 摘 要： | 选择健康状况良好、体重相似、出生日期相近的中国荷斯坦育成母牛5只作为试验对象,采用全收粪法研究育成母牛在一年四季中产粪量及粪污染物（N、P、Cu、Zn和有机质）排放量的变化情况及其规律.结果表明：不同季节间育成母牛产粪量与粪样中机质及N、P、Cu、Zn污染物的排放量均存在着极显著（P＜0.01）或显著（P＜0.05）的差别,因此,根据不同季节产粪量及粪中污染物排泄规律来研究配置符合育成母牛的均衡饲料配方,可达到既满足育成母牛的生产需要,又能最大限度地降低污染物排放量,减少奶牛场污染的目的.

| Abstract: | chinese holstein Growing cows with good health, similar weight, and similar date ofbirth were choose as test objects. The faecal output and pollutant emissionsfN, P, Cu Zn and Organic matter） of the Growing cows were screened in one year round. The results showed that, season changing had extremely significant （P 〈 0.01） or significant （P 〈 0.05） effects on the faecal output and Organic matter ,N, P, Cu, Zn pollutant emissions of the Growing cows. So according to the pattern of faecal output and pollutant discharge in faecal on different seasons,re-arrange the feed formula was not only to meet the production needs of growing cows, but also minimize the discharge of pollutants and reduce the pollution of the dairy farm. |
