| Abstract: | As the rapid development of China's dairy farming industry, environmental problems caused by nitrogen emissions from dairy cattle have been increasingly concerned. Therefore, how to reduce nitrogen emissions of dairy cattle is being a hot topic. This review summerizes the nutritional factors of nitrogen utilization efficiency to improve N-utilization efficiency,decrease nitrogen emission and reduce environmental pressure, based on relevant papers. |
