In the system of full-fledged poultry feeding, particular importance is attached to providing them with mineral substances. The purpose of this study was to determine the effect of the Apimin mineral additive based on bee podmore on the content of zinc, copper, magnesium, and iron in the meat, liver, and bone tissue of quails. During the study, the following methods were used: zootechnical (to analyse the productivity of quails), physiological (to determine the digestibility of nutrients in the poultry diet), biochemical (to analyse the content of minerals in muscles, liver, and tubular bones), morphological (to determine the meat qualities of quails: mass of edible parts, meat carcasses), statistical (to determine the presence or absence of a substantial difference between the values). Justification of the effectiveness of feeding the Apimin additive was carried out based on a comprehensive study on the chemical composition of Apimin, retention of minerals, meat indicators, dynamics of zinc, copper, iron, magnesium content in muscle, bone, and liver tissues of quail. The research was conducted on Pharaoh meat quail from 1 to 56 days of age and quails from 60 to 120 days. Apimin contains calcium, magnesium, iron, zinc, manganese, phosphorus, silicon, and selenium. Feeding Apimin increases metabolism, the digestibility of copper was higher by 21.7%, zinc -by 5.9%, iron -by 8.9%, and magnesiumby 12.9%. Including the additive in the diet influenced increasing muscle mass, the ratio of pulp to bone was higher by 0.26. The content of zinc in pectoral muscles increased by 15.6%, in femoral and lower leg muscles by 2.6%, in the liver -by 5.3%; in pectoral muscles iron increased by 5.1%, in liver-by 13.1%. The copper content was 8.0% higher in the thigh and lower leg muscles, 3.2% higher in the liver, and 14.0% higher in the pectoral muscles. No effect of Apimin on magnesium content was found. With age,

The mineral elements contained in poultry feed do not fully meet their needs. Therefore, the elements that are lacking in the diet are introduced into the feed or feed mixtures to ensure mineral integrity. The aim of the experiment was to research the cobalt chelate complex effect on live weight, weight gain, slaughter quality and hematological parameters of Pharaoh quails.Scientific studies of the cobalt chelate complex effect on quail productivity were conducted on a research farm of Vinnytsia National Agrarian University. Two 20-bird groups were formed on the principle of analogues. The experiment lasted for 42 days, i.e., equalization period lasted for five days, and the main period lasted for 37 days.Control slaughter was performed at the end of the experiment, four heads from each group were slaughtered to determine the main indicators of slaughter and blood. The quails additionally fed by the cobalt chelate complex outnumbered their control counterparts in life weight, i.e., females by 8.5 % (P ≥ 0.001) and males by 7.9 % (P ≥ 0.001).Feeding supplements increases the absolute increase by 8.5 % (P ≥ 0.001) in female quails and by 8.1 % (P ≥ 0.001) in male quails of group II than in the control group.Due to the action of the cobalt chelate complex in group ІІ, feed consumption per 1 kg of growth is reduced in females by 6.62 % and males by 6.12 % relative to control counterparts.In group ІІ, the pre-slaughter live weight of quails increased by 7.7 % (P ≥ 0.05), the gutted carcass increased by 8.1 % (P ≥ 0.05) and the gizzard weight increased by 7.8 % (P ≥ 0.05) than the control indicator.The cobalt chelate complexapplication increases the weight of the breast by 12.1 % (P ≥ 0.01) and thigh by 14.3 % (P ≥ 0.05) in group II relative to control analogues. In group II quails of the amount of hemoglobin increases by 7.2 % (P ≥ 0.05) under the action of the researched supplement in comparison with the control sample.

The purpose of the study was the effect of lysine in the diets on the performance and slaughter indices of pigs during fattening. Young pigs of the experimental group, for the introduction to the diet of lysine, for 100 days of fattening had a greater live weight of 7.7 kg, or 6.4%. Control slaughter of pigs about the same indices of slaughter output of carcasses at the level of 84.0-86% in the experimental with a difference of slaughter weight by 4.3 kg in favor of the experimental group. A lower yield of internal fat and average fat thickness of 13.0% in experimental pigs was found, which confirms a more intense synthesis of muscle tissue. The content of total and bound moisture in muscle tissue was higher by 4.7% and 7.5%, respectively, in the pigs of the experimental group against control, but lower by 2.5% of free moisture. The consequence of these indicators is a lower solid content of 4.5% in the experimental group of pigs.

<p><span lang="EN-US">The purpose of the research was to investigate the chemical, mineral and amino acid content of meat of quails fed by biologically active additives based on the submerged bees of apimore, apiminum, aphytoitis. Feeding was carried out with full-fodder mixed fodders from one day to 56 days of age. The control group was fed by this fodder; experimental quails of the 2^nd<span>  </span>group were fed by this fodder with added 3% of the apimore compound; the 3^rd<span>  </span>group was fed also by apimin at the rate of 1.1 g per 1 kg of mixed fodder; the 4^th<span>  </span>group was also fed by apiates at a rate of 200 ml per 1 kg of mixed fodder. Apimor and apimin were thoroughly mixed with feed. The feed additive aphytoitis was drunk with water, certainly, we have taken into consideration daily water consumption of quails. Four birds were slaughtered in each group at the end of experiment. The selection of average samples of muscle tissue was carried out during anatomical disassembly of quail carcasses. Physical and chemical parameters, mineral and amino acid compositions were evaluated for the study of the effect of feed additives based on submerged bees on muscle quality. In the control group, the ratio of pulp and bone was 3.81:1, in the experimental group it was 4.07-4.2: 1. Quails fed by apiite had the highest rate of breast meatiness; it was 4.3% (p &lt;0.001) higher than in the control group. The nutritional value of white quail meat of the 2^nd group was significantly higher by 7.2% (p &lt;0.01), and in the 3^rd and 4^th groups it was lower, respectively, by 0.6% and 1.3%. The nutritional value of white meat protein is caused by the presence of essential amino acids in it. A noticeable increase of these amino acids in poultry meat of experimental groups indicated an improvement of its dietary qualities. Under the action of apivite valine increased by 2.1% (p &lt;0.001), lysine increased by 3.6% (p &lt;0.001) in the poultry meat; under the action of apimor content of threonine increased the by 8.5% (p &lt;0.001), methionine increased by 9.8% (p &lt;0.01), and phenylalanine increased by 11.2% (p &lt;0.001). Feeding by the researched feed additives influenced the increase of calcium in white meat quail by 37.7-40.5% (p &lt;0.001), phosphorus by 8.9-17.4% (p &lt;0.001). Usage of apivite increased the cuprum content by 22.7% (p &lt;0.001). The quail meat of the 4^th group was characterized by the highest content of zinc, it was by 23.3% more than the control (p &lt;0.001), the 2nd and 3rd groups had more by 5.5% and 6.7% respectively. There is a tendency to increase the iron content in the experimental groups by 5.1 to 15.6% (p &lt;0.01). In studies, the content of cadmium was lower than the <span>threshold limit value</span> under the action of the apimore by 6.0%, apimin by 8.0 % and apivite by 34.0 %, plumbum content was lower by 36.6%, 31.4% and 32.6% respectively. The best indicators for reducing cadmium content in the chest muscles had the 4^th group under the action of aphids, plymbum had the 2^nd group under the action of apimor. According to the results of our research, the quality of quail meat from experimental groups significantly exceeds the quality of their analogues in the control group.</span></p>
