Symbiotic preparation in sales of silver-black foxes

Currently, in zoo breeding, the development and introduction of new fodder and nutritional supplements to feed the fur-bearing animals, which allow to increase the nutritional and biological usefulness of rations, and also to reduce their cost, have become urgent. The modern forms of biologically active additives of the new generation include sorbed forms of probiotic and prebiotic preparations, which include bacteria immobilized on solid sorbent particles. It has been experimentally established that the use of a symbiotic drug in the rations of foxes at the optimal dose allows to increase the usefulness of animal feeding, the preservation and dynamics of growth, improve the morphological and biochemical indicators of blood, the structural and functional state of internal organs, and the level and quality of the products obtained from them and the profitability of production.
