In many countries, quail breeding is organized on a large scale, using modern industrial forms of production. Due to quail farming, the range of dietary foodstuff s necessary for a person is expanding. When rearing and housing this species of poultry, its complete feeding is of particular importance, because health and productivity depend not only on the presence of protein, energy, fats in the compound feed, but also on the amount and ratio of minerals in it, which are a necessary component of any diet. The introduction of beech fl our containing lignocellulose, which relatively recently began to be used for animal feeding as a source of high-quality dietary fiber, can increase the availability of feed nutrients. The purpose of the research was to study the influence of compound feed with the introduction of 1 % beech fl our in different rearing periods on the metabolism and productivity of quails. The results of the influence of complete nutrient-balanced compound feed with beech fl our on zootechnical and economic indicators in the rearing of quailshave been presented in the article. It has been found that expenditures of feed per 1 kg of live weight gain of poultry of the experimental groups were lower by 3,10 % due to better absorption of nutrients. The live weight of quails in the control group at the age of 42 days was 348,25 g and was lower than in the experimental groups by 0,81 and 0,75 %. It has been established that the use of compound feed with 1 % beech fl our is of practical importance in connection with the increase in the productivity of quails and the level of profitability of meat production by 3,2 and 5,5 abs.%.
In order to ensure high productivity of poultry compound feeds are required. However, their production is limited by the lack of high-energy and protein feed in the country. In recent years, many farms are increasingly using the reserve of intensification of feed production, such as the cultivation of new and sparsely distributed forage crops. In this regard, more and more attention is drawn to sugar sorghum, which has received a high rating not only as a productive and drought-resistant crop, but also as the culture that has excellent feed qualities. The results of studying the influence of compound feed with sugar sorghum seeds on zootechnical, physiological and economic indicators when raising broiler chickens have been presented in the article. The researches have been carried out on broiler chickens from the age of one day to 42 days. Two groups of broiler chickens have been formed (control and experimental) per 50 heads in each to conduct the experiment. It has been found during the researches that when input in structure of the diet of 30 % of sugar sorghum the increase of live weight of broilers by 4,16 %, the average daily feed intake 2,82 %, and reduced expenditures of feed per 1 kg of daily gain by 1,67 %. The use of experimental compound feed has increased the digestibility of nutrients by broiler chickens: raw protein by 0,48 %, raw fat by 2,50 %, and raw fiber by 4,93 %. It has been found on the base of the results of anatomical cutting of broiler chicken carcasses that the experimental group contained more edible parts and muscles compared to the control group. The level of profitability of broiler meat production in the experimental group has exceeded the indicator of the control group by 5,4 %.
One of the trends in meat production is to reduce feed expenditures per unit of live weight gain while simultaneously increasing the growth rate, slaughter yield, muscle yield and reducing the content of internal fat. Reducing the fat content in the carcasses of quails will improve the feed conversion and increase the yield of muscle tissue. One of the ways to reduce the prime-cost of poultry products is the introduction of non-traditional promising feed ingredients. The purpose of the research was to study the use of sorghum grain in feeding quails of meat productivity. The results of the infl uence of complete nutrient-balanced compound feed with the introduction of 10 % sorghum on livestock and economic indicators in the rearing of meat quails have been presented the article. It was found that the live weight of quails in the experimental group increased by 0,46 %, while the average daily feed intake decreased by 4,39 %. Feed expenditures per 1 kg of live weight gain of the experimental group were 5,08 % lower due to better assimilation of feed nutrients. It was found according to the results of physiological (balance) experiment that the digestibility of crude protein increased by 6,92 abs.%, crude fat by 0,73 abs.%, crude fi ber by 0,82 abs.%. It was found when calculating economic indicators that the use of sorghum in compound feed for quails allowed to increase the yield of meat and revenue from its sale by 5,81 %. Despite the increase in the total cost of the feed consumed by the experimental group by 1,43 %, the profi t was received by 58,14 % more. The prime-cost of production of 1 kg of quail meat in the experimental group decreased by 6,20 % compared with the control group.
