Abstract

To find out the influence of the mineral supplement “Stimulus +” on the intensity of physiological processes and productivity of bulls. To achieve this goal, we set ourselves the following tasks: 1. To study the effect of the additive “Stimulus +” on the hematological parameters of experimental bulls. 2. Investigate the effect of the drug “Stimulus +” on the quantitative and qualitative indicators of meat (slaughter quality, morphological and chemical composition of carcasses) and its biological value. To study the effect of the mineral supplement “Stimulus +” on the productivity of animals. The obtained results make it possible to correct the diets of experimental animals, which will positively affect erythropoiesis, respiratory function, certain areas of protein, energy, and hydrocarbon metabolism in young cattle, which will increase their productivity and improve the quality of beef obtained from them. Changes in the biochemical parameters of the blood of animals fed the mineral supplement were revealed. It is established to increase the productivity of animals by feeding them a mineral supplement, which indicates a more rational use of physiological resources of the body of experimental animals. It was found that feeding the animals led to an increase in slaughter yield by 3.8 % compared to control. It was found that during long-term storage (14 days) in the meat of animals of the control group, several changes indicate the beginning of spoilage of meat, and the meat of animals fed with mineral supplements was of good quality, as well as veterinary assessment was the best and more resistant to spoilage during storage. In order to prevent microelementosis of fattening cattle for fattening, increase their productivity, improve the physicochemical and veterinary-sanitary indicators of meat, and the profitability of production, we recommend adjusting their diets, according to previous studies.

Highlights

The issue of providing the population of Ukraine with food of animal origin can be considered critical
The main factors that led to this process are the haste of insufficiently substantiated reforms in the agricultural sector, the lack of parity prices for livestock products for a long time, unjustified reduction of livestock in the public sector, the collapse of the material and technical base in animal husbandry, a sharp deterioration of the fodder base, virtually destroyed domestic and domestic dairy cattle and combined productivity, well adapted to the natural and climatic conditions of a region (Farionik & Gnatyuk, 2017; Farionik, 2018; Borshch et al, 2020; 2021; Bashchenko et al, 2021)
The following structure of the diet is recommended: hay, grass cutting – 30–35 %, haylage or silage of good quality – 25– 30, roots – 5–6, concentrated feed – 25–30 %

Summary

Introduction

The issue of providing the population of Ukraine with food of animal origin can be considered critical. This is due to both a sharp decline in livestock and their productivity. The feeding rates of dry cows and heifers are determined by body weight and planned productivity. From the diet of dry cows and heifers should have digestible protein – 110 g, sugar – 90–110, calcium – 9, phosphorus – 6–7, salt – 8–10 g, carotene – 45–50 mg, copper – 8–10, zinc – 50, manganese – 50, cobalt – 0.5– 0.8; iodine – 0.4–0.6 mg, vitamin D2 – 1 thousand IU, tocopherol – 40 mg. The sugar-protein ratio should be 0.8–1.0 (Kravtsiv, 2006; Grymak et al, 2020)
