СРАВНИТЕЛЬНАЯ ОЦЕНКА СОРТОВ ЯРОВОГО ЯЧМЕНЯ ПО КОЛИЧЕСТВУ И КАЧЕСТВУ БЕЛКА

Abstract

To provide a protein-balanced diet for farm animals, a large amount of concentrated feed is included in the feed ration. In our region, spring barley is the main crop. This is due to the fact that barley grain compared with other types of grain provides a relatively large yield of livestock products. In recent years, with the inclusion of breeding varieties in the State Register simultaneously with indicators of grain yield of spring barley, attention is paid to the yield of protein per unit area of crops of this crop. Under the conditions of the Republic of Tatarstan, providing a stably increased protein yield per 1 hectare of crops, regardless of the weather conditions of the year, the varieties are Kamashevsky, Vakula, Rakhat, Gelios. Along with the amount of protein in the grain of barley for animal husbandry, its quality indicators of protein are important, which is expressed by the ratio of low and high molecular weight proteins. To improve the efficiency of livestock production, agricultural enterprises specializing in the production of pork, it is desirable to cultivate varieties of spring barley with more low molecular weight proteins in the grain. Such varieties are Kamashevsky and Gelios. For agricultural producers engaged in milk production, it is better to cultivate the Rakhat and Timerkhan spring barley varieties, in the grain of which a high proportion is occupied by high-molecular-weight proteins.
