One of the tasks of animal husbandry is the development of methods for rearing young animals to obtain healthy calves with specified indicators of productivity and early insemination. The purpose of the study is to evaluate the effect of a plant based whole milk substitute on the growth rate of calves. For the study, three groups of calves of eight heads each were formed according to the principle of analog pairs. The control group was fed with milk according to the scheme adopted on the farm, while the calves of the first and second experimental groups were given a plant based whole milk substitute. 10 mL of vegetable oil per head was added to the whole milk substitute for the first experimental group of calves and they were accustomed to starter compound feed. The average live weight of calves in groups at birth was within 38 kg. At 3 months of age, the weight of the calves of the control group exceeded the weight of the second experimental group by 2.5 kg but was less than the weight of the calves of the first experimental group by 8.3 kg. At the age of 6 months, the weight of calves of the first experimental group was 175.63 kg, which was more than in the control group by 5.13 kg and exceeded the second experimental group by 8.5 kg. With the beginning of receiving a plant based whole milk substitute, the calves' interest in compound feed increased; by the 20 th day, calves could eat up to 0.6-0.7 kg of the feed per day, bringing the increase in eating to the 45 th day up to 3 kg of compound feed.

The article is devoted to the prevention of mycotoxicosis in poultry farming as one of the main components of effective management of the industry. Despite the step-by-step control, the synergy of mycotoxins has a detrimental effect on the bird's body, especially at the final stage of fattening. Growth inhibition, as well as sudden death syndrome, reduce the economic impact. We tested and proposed for introduction into production the organic sorbent "Toxfin dry", which contributed to improving the sanitary quality of feed and reduced the level of mycotoxins-by 46.3-85.3%. We obtained a positive effect of the use of the mycotoxin adsorbent when introduced into the diets of broiler chickens. The experimental bird was fed mixed feed of various quality. The best productive qualities were possessed by broilers from the 3rd experimental group, where in addition to the mixed feed seeded with mycotoxins, for the prevention purpose, the mycotoxin adsorbent "Toxfin dry"was set. During the experimental work, the bird of the 3rd group was stress-resistant, calmly reacted to the work of the poultry house, timely approached the feeders and drinkers. The live weight at the slaughter age exceeded the results of the analogues by 2.1-6.8%. Feed costs for the production of a unit of production, in comparison with poultry from the 2nd group, decreased by 5.1%. The studies conducted with the help of the test object Tetrahymena Piriformis showed that the relative biological value of the experimental meat samples of the 3rd group was higher than the control indicators -by 1.2%. The introduction of the mycotoxin adsorbent "Toxfin dry" with mixed feed, for preventive purposes, contributed to an increase in the average live weight of broilers -by 4.2%, safety-by 2.8 percentage points and a decrease in feed consumption-by 13.9%. The European Broiler meat Production Efficiency Index increased by 59.6 points. The economic effect of using the mycotoxin adsorbent was 15.4 rubles per 1 ruble of costs. Taking into account the technologies used for raising poultry, as well as the livestock located in the poultry house, the economic effect can increase proportionally. The introduction of mycotoxin adsorbents into the diets of broiler chickens for preventive purposes is a necessary condition for the prevention of mycotoxicosis and, consequently, a guaranteed increase in the profitability of production.
