In the scientific article it is described that one of the conditions for the successful development of livestock is to provide a solid forage base and, in particular, to increase the production and conservation of roughage. The main indicator of the quality of crude feed for livestock is the maximum content of nutrients and vitamins in them.

The quality and nutrition of the hay depend heavily on the biological characteristics of the crops grown on the hay, the phases of their development, the time and height of mowing, the weather conditions, the harvesting technology, the drying time, and so on.

The legumes of the legumes, especially alfalfa, are an excellent source of protein, minerals, and vitamins and are a desirable component in the diet of farm animals. When feeding alfalfa hay, the digestibility of the diet and the assimilation of nutrients increases, resulting in improved animal productivity. When choosing the technology of harvesting hay from alfalfa take into account its biological characteristics.

Lucerne is a fairly valuable forage culture of the legumes family. It is grown in more than 80 countries of all continents of the globe on an area exceeding 355 million hectares in various natural-economic areas and ecological conditions: from moderately taiga belt to tropics. Alfalfa grows mostly in pure form and as a component of grass mix in hayfields and for the creation of cultural pastures.

The results of the research on determining the mechanical losses of alfalfa leaves, depending on the amount of processing operations on the cutting of the bevelled mass during hay harvesting, are described. The recommendations on choosing the technology of hay harvesting are given.

It was established that the velocity of moisture distribution of mowed alfalfa grass and the nutritive value of hay are closely related to the effect of solar radiation and the multiplicity of roller cultivation during drying.

It has been determined that during a single cultivating roll during the drying period of alfalfa herbs reduces losses of dry matter by 2.6-4.5%, positively affects the chemical composition of the hay and creates the best conditions for the preservation of nutrients and carotene
