Hulless barley in compound feed for quails

Abstract

In recent years, the Russian poultry industry has been successfully developing because of the use of modern crosses, as well as technologies for poultry housing and feeding. The development of quail farming as an eff ective source of dietary and delicacy products is promising. One of the most important conditions for successful breeding of quails is the organization of complete feeding, which involves the use of high-quality protein and energy feed in the diets. It is very important to maximize the use of local raw materials. In this series, a special place is occupied by hulless barley, which is characterized by a reduced content of hard-to-digest fi ber, and therefore has the increased nutritional value for poultry. Therefore, it is of particular relevance to study the input of various varieties of hulless barley in the composition of compound feed for poultry. The purpose of the research was to study the infl uence of compound feed using hulless barley of Siberian selection on the meat productivity of quails. The results of the study on quails using compound feed with 10 % hulless barley have been presented in the article. It has been found that the expenditures of feed per 1 kg of live weight gain in the experimental group of quails have been higher by 3,6 % due to better assimilation of feed nutrients. The live weight of quails in the experimental group has been increased by 4,31 %, while the average daily feed intake has been increased by 0,62 %. Data from the balance experiment have shown that protein digestibility has increased by 1,81 % in the experimental group. It has been found that the use of compound feed with 10 % of hulless barley is of practical signifi cance in relation with the increase in the productivity of quails and the profi tability of meat production by 8,3 %.
