“…Так, на промислових комплексах з виробництва молока у високопродуктивних корів часто фіксуються порушення обміну речовин, ураження скелета, розлади відтворювальної функції, післяродові ускладнення. Однією з важливих причин цих порушень вчені вважають дисбаланс мінеральних елементів, у тому числі мікроелементів внаслідок недостатнього надходження їх в організм, а також засвоєння їх з кормів, інтенсивне виділення з молоком, підвищеної потреби у них високопродуктивних тварин (Bomko & Havturіna, 2015;Khomyn et al, 2017;Bomko et al, 2020;Kropyvka et al, 2021).…”

The intensification of livestock farming is aimed at a comprehensive increase in the production of milk, meat, wool, and other products by increasing the productivity of livestock and poultry and obtaining the maximum amount of product per unit of feed consumed with the lowest possible labor and cost. One of the main ways to increase animal productivity is through proper feeding. An imbalance in the rations in terms of essential and biologically active substances leads to metabolic disorders, a decrease in natural immunity, and diseases of the reproductive system, negatively affecting economic efficiency. The current use of industrial technologies for harvesting roughage and juicy feed is often violated, which leads to a decrease in its quality and high demand for protein, vitamins, and trace elements; in this regard, it is necessary to improve existing and look for new methods of production, evaluation, and use of feed and feed additives. Minerals ingested with water and feed play an essential role in animal nutrition. Quite often, both an excess of some and a lack of other trace elements are detected, which leads to a decrease in animal productivity and a deterioration in the quality of the products obtained from them. The lack of mineral elements can cause significant economic losses to livestock enterprises due to the massive occurrence of animal diseases and metabolic disorders, especially in the winter and spring. Trace elements play an essential role in animal nutrition, as they considerably impact the body's defenses, hematopoiesis, endocrine glands, and digestive tract microflora, participate in protein biosynthesis, and regulate metabolism. The extent to which minerals are used in the diet depends not only on their quantity and appropriate ratio but also, to a large extent, on the level of the organic part of the diet (proteins, fats, carbohydrates) and vitamins. It has been proven that the additional introduction of deficient trace elements into the diet of animals increases their levels in the body, primarily in the liver. Thus, when determining the need for mineral elements in animals, their ratio to other biologically active substances should be considered based on balanced feeding. However, it should be noted that the level of absorption of trace elements by animals largely depends on the form of their compounds.

“…Корів було розділено на п'ять груп: одну контрольну і чотири дослідні. Контролем слу-жила оптимальна доза змішанолігандних комплексів Цинку, Мангану й Кобальту, яка була встановлена в попередньому досліді (Kropyvka & Bomko, 2017;Bomko, 2020) з концентрацією в 1 кг сухої речовини (СР) кормосуміші (КС), мг: Цинку -60,8; Мангану -60,8 і Кобальту -0,78. Для 2-ї дослідної групи концентрацію цих мікроелементів збільшили на 10 %, а в 3й -навпаки, зменшили на цю кількість.…”

The article deals with the results of research to study the digestibility of nutrients in the ration and metabolism of Nitrogen, Zinc and Manganese in high-yielding Holstein cows of German selection in the first period of lactation for feeding mixed ligand complexes of Zinc, Manganese and Cobalt. The research was performed in the conditions of Terezyne Ltd., Bila Tserkva district, Kyiv region. There was an increase in the coefficients of digestibility of dry matter in cows of the 2nd-5th experimental groups compared with animals of the 1st control group, respectively by 1.8–3.5 % (P < 0.05); organic matter by 0.3–2.5 %; crude protein by 0.5–4.2 % (P < 0.05 – P < 0.01); crude fat by 1.1–1.8 %; crude fiber by 1.3–3.3 % and nitrogen-free extractives by 2.1–4.2 %. Cows of the experimental groups consumed more Nitrogen than the cows of the control group: 20.18 g or 2.4 % – the 2nd group, 55.06 g or 6.6 % – the 3rd, 42.52 g or 5, 1 % – 4th and 28.98 g or 3.5 % – 5th experimental group due to better eating of the feed mixture. General consumption level of Nitrogen in relation to excreted with milk and deposited in the body of cows of the control group was 32.02 %, and in animals of the 2nd, 3rd, 4th and 5th experimental groups – 33.59 %; 37.31; 36.99 and 34.97 %. In relation to the total digested amount, the proportion of Nitrogen deposited in the body and excreted with milk in animals of the control group was 42.38 %, and in the experimental – 44.25–47.34 %. Doses of Zinc, which provided its existing rate of 54–85 % due to the mixed ligand complex, positively influenced on the the metabolism of trace elements in the organism of experimental cows. Assimilation of Zinc in the organism was determined by the amount of its secretions with milk and deposits in the body and in absolute terms it was the lowest in cows of the 4th and 5th experimental groups – 562.7 mg and 671.6 mg against 740.8 mg in the 1st control group and the largest – 784.7 mg and 801.3 mg in animals of the 2nd and 3rd experimental groups. The use of a mixed ligand complex of manganese ensured its positive balance in the organism of cows and the absorption of the trace element in the organism of experimental cows ranged from 22.5 % in the 2nd experimental group to 33.2 % in the 3rd experimental group. The best indicators for the metabolism of Nitrogen, Zinc and Manganese were got in the third experimental group whose cows were fed a feed mixture, that in 1 kg of DM contained, mg: Zinc – 54.7; Manganese – 54.7; Cobalt – 0.7; Selenium – 0.3; Copper – 12 and Iodine – 1.1.

“…According to the recommendations of Ukrainian researchers, the concentration of zinc and manganese in 1 kg of dry matter in the diets of high-yielding cows with an average daily yield of 35 kg of milk or more should be 70 mg; cobalt -0.9, cuprum -11, iodine -1, and selenium -0.3 mg. However, the researchers found that the addition of mixed ligand complexes of zinc, manganese, and cobalt to the diets of dairy cows during the first 100 days of lactation to ensure the concentration of these trace elements in 1 kg of dry matter, respectively, 54.7 mg; 54.7, and 0.7 mg had a positive effect on their productivity per concentration (Bomko et al, 2019).…”
