The potentiality of phytoprophylactic correction of immunodeficiency conditions in agricultural animals

Abstract

The paper presents the results of feeding dairy cattle with vitamin-herbal flour from safflower leuzea, sandy sainfoin and meadow clover in order to improve metabolic processes in the body and reproductive function of cows. Zootechnical and veterinary sciences provide for the implementation and development of progressive modern technologies for the production of livestock products and raw materials. In line with the ongoing state policy of import substitution, the need of increasing the production food products, cow's milk and beef meat being of special importance. To ensure sustainable growth in the livestock and productivity of cattle, it is necessary to have healthy purebred young stock. In 2016-2020 in the Perm Region, at livestock farms of all categories non-infectious pathology of the digestive system was recorded in cattle in 42-44% of cases, including 76,7% of cases in young animals, based on the Form 2-vet data. The analysis of the incidence of respiratory diseases in cattle in the Perm Region showed that respiratory diseases of calves are widespread (25-31% of the total number of patients with non-communicable diseases). This pathology is difficult at the age of transition to group keeping of animals. Despite the extensive arsenal of immunomodulators of natural and synthetic origin accumulated in recent decades, the question of finding the most active, environmentally friendly means remains relevant. Under conditions of modern dairy farming, the use of various feed additives, premixes, probiotic preparations, including dry plant raw materials as vitamin-herbal flour, has become widespread in animal feeding, providing a high level of productivity and reducing the cost of metabolic energy per unit of production and the safety of young animals. The research results can be used in the selection of perennial grasses, in the fields of seed growing and fodder production, when feeding animals in farms of any form of ownership.
