Nitrogen metabolism in the body of cows when feeding in the ration of haylage from Galega orientalis

The article is devoted to the actual problem of studying the digestibility and metabolism of nitrogen in the body of cows when they feed haylage from the Galega orientalis . The experiment was conducted on winter rations of feeding, on black-motley cows with a productivity of 4500-5000 kg of milk. In the experiments, the methodological principle of ‘unity of intergroup differences' and the presence of control animals was provided, which allowed to obtain objective data and reliable conclusions based on mathematical processing. An experimental assessment of haylage from Galega orientalis and Trifolium pratense is given, the influence of crops on the digestibility and use of nitrogen is studied. It was noted that the inclusion in the ration of experienced cows of haylage from Galega orientalis dairy had a beneficial effect on the digestibility of nutrients, the use of nitrogen from feed and its exchange in animals. The results showed that the animals of the experimental group consumed more nitrogen by 35...
