In course of the research there was studied the efficiency of use of new preservatives, prepared on a base of local raw material, for ensilage fodder preparation and milk and beef production. The research on studying of chemical composition and nutritive value of silo, preserved with a sapropel feed additive was conducted in the conditions of the Republic of Belarus at the Grodno State Agrarian University. As a result of realized research it was revealed that the preparation of the silo with the sapropel feed additive made it possible to lower losses of dry substance (7.9-10.6%), crude protein (12.6-15.0%), sugar (27-55%), carotin (20.5-23.6%). In 1 kg of dry substance of silos it was contained 9.31-9.70 Mj of exchange energy and 86.7-89.5 g of digest protein. Inclusion in diets of cattle of the silo with the sapropel feed additive rendered positive influence on productivity. Daily average yields of milk increased on 5.7-7.3%, gains of young growth -on 5.9-6.5%. The silo with the sapropel feed additive did not render negative influence on lethal and meat qualities of calves.
