The role of biologically active substances - phytoextracts of larch bark in the productivity of pigs

The use of phytoextracts from various parts of woody vegetation, as biologically active substances that have a positive effect on the productivity and metabolic health of animals, is increasingly used in animal husbandry in general including in pig farming. Hence, the use of production waste - Dahurian larch bark, namely its extract in the diet of large white x landrace crossbred piglets during the rearing period after weaning and before fattening is relevant. The purpose of the research is to study the effect of Dahurian larch extract on growth and development, homeostasis, antioxidant protection of the body and microbiocenosis of the contents of the large intestine of young pigs. It has been shown that the use of Dahurian larch bark extract in feeding large white x landrace crossbred piglets at a dose of 25 mg/per 1 kg of live weight per day during the growing period from weaning to fattening, that is, at the most critical moment of their life - the restructuring of all physiological processes and functions in their body, changes in behavioral reactions, changes in partners, location, etc., had a positive effect on metabolic processes (protein-nitrogen metabolism), functional state of the liver and morphohematological indicators, as a result of which their genetically more fully manifested conditioned productivity potential, the clinical condition of the body and the safety of the livestock have improved.
