Abstract

The effectiveness of modern poultry farming depends on many factors, the main of which is the food supply. In addition, preventive work, including vaccination and preventive measures that increase the resistance of chickens and their survival, is an important factor. The article presents comparative results on the use of various adaptogens. The aim of the study was to evaluate the macro-microstructure of the broiler liver when using adaptogens of various origins during growth and fattening. The objectives of the study were: to evaluate changes in the macro- and microstructure of the liver after fattening broilers, when feeding adaptogens of various origins, while comparing the preventive effectiveness of adaptogens in diseases of the digestive system, the effectiveness of fattening and the safety of livestock. For the first time, an organoleptic veterinary and sanitary assessment of the quality of giblets was carried out in comparison with microscopic changes after feeding various feed additives of domestic production with the properties of adaptogens. An adaptogen has been identified that maximally reduces the incidence of broilers in diseases of the digestive system and liver, the main organ responsible for metabolic processes in the body. In addition, an adaptogen has been identified that allows maximizing the efficiency of using the feed base for growing and fattening broilers. Such an adaptogen is an organic adaptogen – peat-sapropel concentrate. The effectiveness of the used domestic feed additives, which are adaptogens, depends on the composition of these additives, it is mainly determined by the mineral composition and biologically active additives included in their composition. The used feed additives have organoprotective properties, increase the nonspecific resistance of the bird's body, increase the efficiency of using the feed base, and increase the survival rate of chickens. Accordingly, they increase the efficiency of meat and poultry farming.
