Use of a comprehensive feed additive made of zeolites, dihydroquercetin and sea algae in feeding of laying hens

The study of the influence of a complex feed additive of zeolites, dihydroquercetin and sea algae on the productivity of laying hens and metabolic processes in the body of poultry taking into account modern socio-economic factors is a relevant area in poultry farming. The purpose of the research was to study the use of a complex feed additive of zeolites, dihydroquercetin and sea algae in feeding of laying hens. In the course of the research a detailed comparative assessment of the influence of zeolites from the Vanginskoye, Innokentyevskoye and Khongurinskoye deposits of the Amur Region on the productive characteristics, quality of the products obtained and metabolic processes in the body of laying hens was carried out. An optimal combination of ingredients (zeolites, dihydroquercetin and dried sea algae) was developed to create a complex feed additive. The economic effect of its use in the diet of laying hens was estimated. It was found that in terms of economic feasibility of the use of complex additives with different combinations of components the hens of the 2nd experimental group had the best indicators. The additional income for the experimental period in this group was 2358.8 rubles while the best group in terms of productive traits (3rd experimental) turned out to be economically unprofitable, which was due to the high cost of sea algae. On the base of experiments and analysis of the data obtained we recommend additionally including 5 g of zeolites and 5 mg of dihydroquercetin per head/day in the diet for laying hens. This will increase the egg productivity of hens by more than 7 % and increase the economic effi ciency of production.
