The problem of increasing of livestock and poultry has led scientists to look for measures to improve productivity and reduce costs. One way to solve this problem is to use balancing supplements in the feeding. The study of feeding by protein-vitamin-mineral feed supplement “Efiprot” was carried out on three groups of young white pigs, 12 heads in each group. The experiment consisted of leveling of 15 and a basic period of 127 days. During the rearing period, the animals consumed the feed according to the growth phases, increasing the amount from 1 kg/head (8–15 kg of live weight), up to 1.5 kg/head per day (15–35 kg of live weight) and from 2 kg/head (35–65 kg of live weight) and up to 2.5 kg/head. per day (65–110 kg of live weight). While using in feeding of young pigs of PVMS “Efiprot”, a positive productive effect was obtained. Thus, when introduced to the diet of the tested yong pig the PVMS, the average daily growth of animals has increased by 33–58 g. Accordingly, has increased the final live weight of the animals by 4.05–7.18 kg against the control level. Due to the result of the studies, carrying out the control slaughter, it was found that feeding of the protein-vitamin-mineral supplement “Efiprot” for young pigs on rearing does not have a probable effect on the weight of the stomach, but causes changes in the thickness of the wall of the cardiac zone by 0.24 mm (2.75 %), and reducing the wall thickness relative to the control by 1.04 mm (11.91 %). In the fundus zone of the stomach, there is a tendency to thicken the walls due to the mucous and sere-muscular membranes by 0.36 mm (6.75 %) and 0.35 mm (6.56 %). In the study of the pyloric zone, the thickness of the walls was decreased by 0.46 mm (3.13 %) and 0.73 mm (4.97 %) compared to the control group.The reaction of the intestine to feeding of “Efiprot” to young pigs is caused by an increase in weight and length of 0.06 – 0.2 kg and 0.5 m – 0.83 m. Also it is shown a slight decrease in the thickness of the hollow shell by 0.5 mm (18.3 %) in the second group of animals 0.21 mm (7.69 %). A significant difference was found in the structure of the colon of experimental animals, where there was an increase in wall thickness in the first group by 0.13 mm (5.75 %) and a decrease in the second group by 0.16 mm (7.07 %).
The article provides overview and analysis of scientific publications and developments on the use of protein-vitamin-mineral supplements for farm animals and poultry. The analysis of various components that were introduced into diets containing of protein-vitamin-mineral supplements in feeding farm animals and the importance of biological significance for the livestock sector and the as a whole is carried out. It is summarized and analyzed the foreign and domestic editions, namely – information on the qualitative part taken by protein-vitamin -mineral supplements in the total production of feed for farm animals and poultry. The recipes, composition of the component ratio for different species of animals and poultry as well as the percentage for certain sex-age groups of animals are given. It is established that the expediency of proper mixing of feed positively affects the quality of the finished product and, therefore, the provision of animal increment, which are the main requirements of the modern livestock market in Ukraine and abroad. Modern researches of scientists and practitioners on protein-vitamin-mineral supplements, as well as the market of domestic and foreign manufacturers of products for farm animals and poultry are analyzed. The dependence of introducing into the feed additive of new components, which both improve productivity, digestibility, and improve the quality of finished products, is studied and therefore reduces feed costs by 1 kg of live weight. The data of digestibility of fed protein-vitamin-mineral supplements in the composition of rations, hematological parameters of blood, morphological data, as well as productive indicators are average daily increments, depending on the growth phase of farm animals and poultry. The article presents advanced establishments-developers of protein-vitamin-mineral supplements, as well as producers of new high-quality equipment for mixing BWMD and components of the diet for different periods and sex-age groups of farm animals and poultry in the domestic and foreign markets.
