DescriptionThe article presents the results of studying the influence of the method of treatment before storage and storage parameters, including the relative air humidity, on the value of general losses of carrots. The taproots treatment before putting into storage was carried out with electromagnetic fields of extremely low frequency and the bio-preparation Vitaplan. After treatment, the taproots were kept at a temperature of +2±1°С for 56 days and +25±1°С for 21 days. In the process, the relative air humidity was changed from 40 to 90%. At a storage temperature of +2±1°C, the lowest total loss was observed at a relative humidity of 90%. At a storage temperature of +25±1°С, the optimal, from the point of view of decreasing the general losses, turned out to be the relative air humidity of 70%: with decreasing relative air humidity to 40%, significant increase of natural losses was observed, because the taproots were losing water intensively, and with increasing relative air humidity to 90%, favorable conditions were created for the growth of pathogenic microflora, which caused significant losses from the microbiological decay. The method of pretreatment of carrot taproots, providing the lowest general loss during storage in all the studied conditions, was joint treatment with ELF EMF and the bio-preparation called Vitaplan

DescriptionSulphitation of semiproducts of sugar production has a significant influence on the course of processes in the refining of both sugar beet and cane sugar. The insufficient degree of adsorption of sulfurous anhydride has a negative impact on the environment as well as on the technical staff, if it gets into production premises, caused not so much by contingencies, but by shortcomings in the equipment used. In the article, we describe the main types of constructions of sulphitation devices used in the sugar industry, their drafts are shown, their advantages and disadvantages are considered

PROBIOTIC FEED ADDITIVES USED IN PIG FARMING
DescriptionThe article provides a review of domestic patent information on the effectiveness of using modern probiotic feed additives in pig farming practice. The inclusion of probiotic feed additives in the diets of pigs is aimed at excluding pathogenic and opportunistic microflora from the intestinal microbiocenosis, increasing the productive action of feed and intensifying metabolic and immune processes in the organism. The introduction of probiotic feed additives into the diet of pregnant sow and suckling pigs, as well as weaned piglets, allows achieving high indicators for the safety and productivity of young animals, which is very important for the cost-effective development of production. The ability of probiotic feed additives to normalize the microflora of the gastrointestinal tract of newborn piglets provides increased resistance to mass gastrointestinal diseases, as well as increasing the safety and viability of piglets. Thus, probiotic feed additives are an important component of the modern diet of farm animals at all stages of their development. At the same time, the most popular and effective for modern pig farming are multicomponent probiotic feed additives that contain a complex of probiotic cultures with different biological effects on the organism, sorbents that often act as prebiotics, enzyme preparations and other biologically active substances that provide a positive multifunctional effect on the organism of farm animals

THE EFFECT OF FEED RATIONS ON THE PRODUCTIVITY OF HOLSTEIN-FRIESIAN BREED BULL CALVES
DescriptionThe article presents the results of scientific and industrial experience in identifying the effect of feed additives on the productivity and biochemical parameters of bull calves’ blood in fattening. The calves of Holstein-Friesian breed at the age of 30 days were selected as objects of research. In the diet of the bull calves of the experimental groups, we used feed additives in the main diet: probiotic feed additive “Cellobacterin+”, feed vitamin-mineral concentrate “Tetra+”, complex feed concentrate. We found that the most active weight gain is observed in the group of calves that received complex feed concentrate. In all experimental groups of bull calves, we observed a decrease in the activity of hepato-indicator enzymes and a thymol sample. Based on the data obtained, it can be concluded that the use of the complex feed concentrate containing biologically active substances and the additive “Cellobacterin+” (in comparison with the control and other experimental groups) leads to maximizing the increase in the average mass of bull calves, which is associated with the synergistic effect of biologically active substances and living microorganisms Enterococcus faecium 1 - 35. The same tendency is observed with respect to the activity of hepato-indicator enzymes - AST and ALT, which, compared with the control group, decreases by 35.6% and 28.2%, respectively

05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
DescriptionThe article presents the results of studying the influence of some types of packaging materials used in conjunction with Inter Fresh’s ethylene absorber (sachets) on commercial quality and losses of Alexandria zucchini, Lyubov sweet pepper and tomatoes cv. Inkas during storage. The study was carried out using StePac Xtend bags, creating a modified atmosphere. The objects of research were stored for 14 days at a temperature of 8 – 10 °С and air relative humidity of 90±3 %. One sachet for ethylene absorption was placed in Xtend bags. It was found that when stored under these conditions, the total weight loss is: for tomatoes – 0.3% when using Xtend bags and Inter Fresh ethylene absorbers, 1.8% when using traditional packaging materials; for zucchini – 0.4% when using Xtend bags and Inter Fresh ethylene absorbers, 1.6% when using traditional packaging materials. Losses associated with microbiological damage during storage of zucchini and tomatoes were not observed. During storage of sweet pepper microbiological spoilage took place, which, apparently, was the result of increased contamination with pathogenic microorganisms
