Purpose: This collection aims to discuss the current state of nitrogen pollution from dairy livestock and present recommendations to increase the nitrogen use efficiency of dairy livestock. Method and findings: In the study, articles published in scientific journals and data on the web pages of the relevant institutions on the subject were used. The ration nitrogen use efficiency of dairy cows is generally low. One of the most important issues related to nitrogen loss in milk cattle rations is the environment. A significant amount of nitrogen, especially from the urine, is mixed into the atmosphere by turning into ammonia at the end of the enzyme destruction. The formation of acid rain with thin particles, nitrate pollution in underground waters and increased cetrofikation in soil-surface waters are the negative effects of ammonia on the environment. Ammonia also contributes to the formation of greenhouse gases through diaposit monoxide. Generally, the production of more ammonia than microorganisms can use in the ruminate increases nitrogen loss through urine. Another cause of nitrogen loss in ruminants is the use of amino acids for glyconeogenesis purposes instead of protein synthesis. In addition, the proportions containing imbalanced amino acids that are not adjusted according to the milk protein synthesis requirement increase nitrogen loss. The importance and effect of the study: Ammonia release from subtility can be significantly reduced by some cultivation, nutrition and subtility applications. Reducing ammonia emissions from dairy livestock is important for a sustainable environment along with its benefits to producers.
