Recently, positive results have been achieved to reduce the risk of mycotoxicosis in meat poultry by rational use of various feed antioxidants, which inhibit processes of lipid peroxidation in the body and increase its immunity. The research aims to study the effect of different dosages of feed antioxidant Epofen on the basic economic and useful performance and digestive enzyme activity of broiler chickens grown on wheat-sorghumsunflower-based diets with tolerance level of T-2 toxin. To achieve this aim, the experiment using day-old "COBB-500" broiler chickens, which by the analogue scale were divided into 4 groups, was carried out on the poultry farm, agricultural production cooperative "Batraz", RNO-Alania. The resulting digital material was processed biometrically using the information program Excel. The research found that the best dose of feeding Epofen by reducing the risk of T-2 toxicosis in broilers is 200 g/t feed, which improves the basic economic and useful qualities and intensification of feed enzymolysis. At the same time versus counterparts from the control group, broilers in the second experimental group had increase in poultry stock safety by 4.0%, gross and daily average gainby 9.29% (P<0.05). Due to a better level of T-2 toxin detoxification by introducing preparation Epofen in mixed feed at a dose of 200 g/t feed, in the muscular stomach content of meat chickens of the second experimental group was significant (P<0.05) increase in protease activity by 11.61%, cellulaseby 19.93% and amylaseby 14.43%. Also, the broilers of the second experimental group showed a significant (P<0.05) increase in the activity of proteinases in the chyme of the small intestine by 15.50%. cellulaseby 14.19% and amylaseby 15.12%.

“…Among these drugs are well established enzyme preparations (Anchikov & Kislyuk, 1999;Kuzmin, 2004 Kaloev et al, 2020.). The feeding of probiotics and enzymes like lecithin was found to be useful in poultry production (Temiraev et al 2020 andKaloev et al 2020) However, it should be borne in mind that high productivity indicators of farm animals and poultry provide for the intensification of metabolic processes in the body, which affect the biochemical status of blood. Blood, due to its buffering properties, quickly reacts, by changing its indicators, to the impact of various feed factors, which are one of the main external factors affecting the blood picture of animals and poultry.…”

The use of new feed factors in poultry feeding is necessarily reflected in the change in blood parameters. The article presents the results of physiological studies on the study of changes in the hematological parameters of laying hens with the additional use of enzyme preparations Sanzaym and Sanfayz 5000, as well as lecithin in their feeding. Scientific and economic experience, during which the main physiological indicators were studied, was carried out in the State Unitary Enterprise of the Breeding Reproductor "Urus-Martanovsky" of the Chechen Republic on laying hens of the Loman Brown breed. As the main diet in the experiment, compound feed was used, prepared on the basis of corn, barley, wheat, sunflower meal. It was fed to a bird of the control group. In addition to the main diet, the livestock of the 1 experimental group were additionally fed two enzyme preparations: Sanzaym (100 g/t of feed) and Sanfayz 5000 (80 g/t of feed). Phospholipid lecithin, in the amount of 10 g/kg of feed, was fed to livestock. The use of enzyme preparations and lecithin increased egg production per average carrier by 24.5 pcs or 8.9%, the intensity of egg production by 7.42%, which made it possible to obtain 245.4 kg or 14.6% more egg mass than the control group.

“…They are necessary to form eubiosis and improve the overall resistance of the bird's body to unfavourable factors. Usually, the number of bifidobacteria which perform some important functions in the body: protect the intestinal mucosa from penetration of pathogenic and opportunistic microorganisms into the blood decreases in the intestine (Kokaeva et al, 2017;Temiraev et al, 2020). The aim of this research was to study the effect of probiotic Bifidum-SHG and antioxidant Santochinum on nutrients digestibility and absorption with aflatoxin B 1 tolerance level in the diets of rearing flocks and laying hens.…”

In the conditions of RNO-Alania the most effective way to protect grain from contamination with mycotoxins is to prevent their formation all the way from the field to the consumer. For this purpose it is necessary to apply the improved technologies of cultivation, treatment, storage, as well as partially to disinfect grain products during grain processing. In the course of the research the MPC excess in T-2-toxin and ochratoxin A concentration in the selected samples of corn, barley and soybeans was not found. At the same time, the content of aflatoxin B 1 in the composition of cereal and legume-based feed ingredients exceeded the MPC. By mixing corn, barley and soybeans, unfavourable in aflatoxin B 1 concentration with other favourable in this toxin ingredients managed to reduce its content in the composition of complete mixed feed PK-5 and PK-6to 0.23 mg/kg. Moreover, aflatoxin B 1 concentration in the formulation of these mixed feeds in both phases of feeding does not exceed the tolerance amount-0.25 mg/kg. According to two metabolism trials using rearing flocks and laying hens, the joint introduction of probiotic Bifidumbacterin at the rate of 5 doses per 200 heads and preparation Santochinum at a dose of 125 g/t feed in the diet with tolerance level of aflatoxin B 1 increased significantly the digestibility coefficients of organic matter, crude protein, crude fiber and nitrogen-free extractives, as well as the best protein conversion into products.
