“…Recently, special attention has been paid to the development of not only dairy, but also the meat industry of cattle breeding [1]. Unfortunately, in our country in recent years, there has been a decrease in the total number of cattle, both meat and dairy areas of productivity [1,3,2,4,5,6]. Thus, in 2021, the number of cattle in agricultural enterprises decreased by 5.3% compared to 2020, of which the number of cows decreased by 3.3% [2,4].…”

In the studies, the growth and development indicators of the Hereford young stock were studied, depending on the origin. The average daily growth of calf bulls aged 824±16.4 g, 8 months – 962.5±14.6 g, 9 months – 981.5±18.6 g, 12 months – 986.1±19.2 g. The height at hips of calf bulls aged 205 days was 109±11.7 cm, 8 months – 111±9.4 g, 9 months – 112±6.8 cm, 12 months – 124±7.9 cm. The average daily increase in heifers aged 205 days was 853.6±11.3 g, 8 months – 854.2±17.5 g, 9 months – 870.3±18.2 g, 12 months – 850±10.5 g, 15 months – 831.1±15.6 g, 18 months – 777.8±16.5 g. The height at hips of calves aged 205 days was 106±9.8 cm, 8 months – 109±7.8 g, 9 months – 110±11.1 cm, 12 months – 118±8.9 cm, 15 months – 121±10.9 cm, 18 months – 125±13.2 cm. It was found that the growth rate of calves and calf bulls on fattening is influenced by the father genotype. When comparing the average live weight of young stock at the age of 18 months, the best results were in calf bulls received from the bull Perets 3989 – 375.8±17.5 kg, this is 3.8 kg more than the same indicator for calf bulls received from the bull Timeline 2930348, and 7.8 kg more than the bull Emulation 2909514, and by the live weight of heifers at the age of 18 months the leader is the Timeline 2930348- 352.6±25.2 kg.

“…Balancing feed due to feed additives entails an increase in the product cost, therefore, preference in feeding farm animals as part of compound feeds in the current period is given to additives of domestic production, such as natural sorbents, enzymes, and others [12,13,14].…”

In this experimental work, the effect of vitamin and mineral concentrate P52-1 of domestic production as part of barley and wheat compound feeds on the growth dynamics of young pigs and their health indicators for the experiment duration was studied. At the same time, the physiological parameters of the health of the studied animals were considered. Morphobiochemical studies of blood allowed to conclude that this feed additive had a positive effect on the metabolism of young pigs in the post-weaning period and during rearing. The result of the use of P52-1 was an accelerated increase in the mass of the test animals of the experimental group compared with the control group in terms of average daily and gross increments. At the same time, in the experimental group of animals, morphobiochemical indicators exceeded those of the control group, while they were within the normal range. The cultivation of young pigs using a multienzymatic premix, of domestic production, provides an average daily increase in animals of the experimental group of over 16%.

When feeding of pigs is organized it is necessary to take into account physiological patterns of development that affect both productivity and reproductive qualities which are based on metabolism. This study considers and investigates the use of Provimi protein-vitamin-mineral supplements (PVMS) in the system of livestock technological modernization. Morphological and biochemical parameters of blood were studied in the control and experimental groups using generally accepted standardized methods. The results were processed using the program STATGU1.XLS. In the course of experimental work, the composition and nutritional value of feeding pigs within 60 days after weaning and 210 days of fattening were evaluated. The influence of Provimi products on their growth, development and metabolism was studied, which is judged by the state of morphobiochemical parameters of blood in the dynamics of growth of animals.The use of PVMS of the aforementioned company has had a positive effect on the growth dynamics as evidenced by an average daily body-weight increase of animals of the experimental group compared to the test one by more than 30%.
