The emissions of nitrogen in dairy production has been one of the elements of ecologi-cal environment problems. With the increased the number of cows, lowering nitrogen excretion of dairy cattle has become a focus, which has to be solved as soon as possible. This article reviewed the measures of relevant nutritional manipulation about reducing the emissions of nitrogen, includ-ing the regulation of rumen protozoa and the technology of protein package, the method of fodder machining and adjusting the formula. In order to improve dairy cow production and reduce the haz-ards of nitrogen emissions on the environment.
