The effectiveness of increasing the productivity of agricultural poultry depends on the extent to which production technologies enable the realization of its genetic potential. The experiment aimed to study the effect of a mineral feed additive containing copper on productivity, growth, and feed consumption in broiler chickens. The scientific and economic experiment was conducted in the conditions of the Vinnytsia National Agrarian University vivarium. For the experiment, 40 broiler chickens of the “Ross-308” cross were selected, and two analog groups of 20 heads each were formed. The experiment lasted 42 days. During the experiment, the broilers of the 1st control group consumed a completely balanced feed. In addition to the diet of the research group, the researched mineral feed supplement was added. Broiler chickens were weighed every week to determine the intensity of growth. According to the results of the experiment, it was established that additional feeding of a mineral feed additive to broiler chickens of the 2nd group increases live weight at 21 days of age by 4.6 % (Р ≤ 0.05), at 28 days of age by 7.1 % (Р ≤ 0.01) in 35 days by 9.5 % (Р ≤ 0.001) and in 42 days by 9.4 % (Р ≤ 0.001), against the control. It was found that with the use of a mineral additive in broilers of the 2nd group, feed consumption per 1 kg of growth is reduced by 7.8 %, compared to the control value. Additional consumption of the researched mineral feed additive in broiler chickens of the 2nd group increases the pre-slaughter live weight by 8.9 %, the weight of non-carcasses by 9.7 % (Р ≤ 0.001), half-carcasses by 10.8 % (Р ≤ 0.01) and patranoi by 13.0 % (Р ≤ 0.001), relative to the control. Feeding the mineral supplement to broilers of the 2nd group increases the mass of pectoral muscles by 9.2 % and thigh muscles by 10.8 % (Р ≤ 0.01), against the control indicator.

“…Науковими дослідженнями застосування різних кормових добавок (серед них: мікроелементи, вітаміни, амінокислоти, фітобіотики, пробіотики, ферменти), які не накопичуються у продукції птахівництва, займається чимало вчених та практиків (Gutyj et al, 2017;Lei et al, 2022). Серед біологічно активних речовин перевага повинна віддаватися добавкам приро-дного походження, в тому числі мінеральним (Downs et al, 2000;Razanova et al, 2022).…”

Mineral elements play an essential role in the metabolic processes carried out in the animal body at the cellular level. They support homeostasis, acid-base balance, and osmotic pressure. Lack of mineral elements leads to disturbances in metabolic metabolism, reduced productivity, and increased morbidity in poultry. Therefore, the research aimed to establish the effect of selenium-containing feed additives on broiler chickens' live weight, gains, feed consumption, slaughter, and hematological indicators. Selenium – exchanges proteins, fats, and carbohydrates to regulate enzymatic and redox reactions. The introduction of selenium into animals' rations contributes to the normalization of metabolism, preventing the accumulation of toxic oxidation products and damage to the cell membrane. The experiment lasted 42 days. Two groups of Ross-308 cross-broiler chickens, 20 heads each, were selected for the experiment. In addition to compound feed, the second experimental group used a mineral feed additive at the rate of 100 g per 1 ton of compound feed. When broiler chickens were fed a mineral feed additive, live weight increased by 4.9 %, average daily weight gain by 4.8 %, and absolute weight gain by 5.0 %, relative to control counterparts. It was established that using a mineral feed additive in feeding broiler chickens of the 2nd group, the consumption of feed per 1 kg of growth decreased by 9.0 %, compared to control analogs. It was found that the pre-slaughter live weight of broiler chickens of the 2nd group increased by 5.0 %, the weight of non-carcass carcass by 5.6 %, half-carcass by 5.5 %, and carcass weight by 6.2 %, compared to the control value. In addition, under the influence of the studied feed additive, the mass of the pectoral muscles in broilers of the 2nd group increases by 16.0 % (Р ≤ 0.05) and thigh muscles by 36.0 % (Р ≤ 0.001) relative to control indicators. It was found that in the broilers of the 2nd group, under the influence of the additive, the slaughter yield of the thigh muscles increased by 29.4 % (Р ≤ 0.05) compared to the control group. It was established that under the action of the mineral supplement, the level of hemoglobin in broiler chickens of the 2nd group increased by 5.3 % (Р ≤ 0.05) relative to the control value.

Vus, U.M., & Kozenko, O.V. (2019). Dynamics of changes in protein metabolism rates in cows depending on the season of the year and the location of the farm. Scientific MessengerProtein metabolism in animals is perhaps the most informative indicator of anthropogenic environmental pollution, because it provides an opportunity to characterize metabolic processes in the body. They are of the utmost importance for the structure and function of all cells, tissues and organs. Proteins reflect the state of the organism, as well as those changes that occur in it under the influence of internal and external factors. We studied the dynamics of changes in indicators in protein metabolism in cows depending on the season of the year and the location of a farm. The research was carried out in two farms of the Lviv region: the Danylo Halytskyj LLC, near the State Mining and Chemical Enterprise "Sirka", and FE "Lelyk" of Zhovkva district, in spring, summer, autumn and winter periods of keeping. The object of research was the blood of 20 cows of Ukrainian Black-Spotted breed. According to the results of the research, a reduction in total protein, relative to the physiological norm of 0.45 g/l. in spring, and by 0.64 g/l in the summer, dysproteinemia, a high level of gamma globulin fraction (50.30%) in cows from the Danylo Halytskyj farm, located in the zone of influence of the State Chemical Medicine Plant "Sirka". In animals FE Lelyk, located in the conventionally clean zone, this indicator was significantly higher, and was 76.14 g/l in spring, and 78.17 g/l in summer, and also in animals of this farm dysproteinemia was not observed. In the autumn, at the end of the summer grazing period of the keeping, the index of total protein tended to decrease in the animals of the Danylo Halytsky's Ltd., and in winter it was normalized and invested in the limits of the physiological norm. Albumin fraction of protein in this group of animals, throughout the search period, had a tendency to increase. In the cows of the FE "Lelyk", the indices of protein metabolism were within the limits of the physiological norm in all periods of research, with the inherent fluctuations in the season of the year. The obtained results due to the content of total protein and protein fractions in the plasma of blood of cows kept in territories with different ecological status indicate that the effect of the activity of the State Chemical Medicine Plant "Sirka" is sufficiently strong on the organism of animals.Динаміка змін показників білкового обміну в корів залежно від сезону року та території розташування господарства У.М.
