Testing of silos from legume-cereal grass mixtures and feed additives in the feeding diets of dairy cows

Abstract

The production approbation of silos prepared from legume-cereal grass mixtures with the use of an unconventional feed crop – eastern goat and preserved with Biosib biopreparation in experimental versions was carried out. The chemical composition and nutritional value of feed were determined, the structure of feeding rations was calculated, the dose of the energy feed additive was determined. In the balance experiment, the digestibility of the main nutrients of feed was calculated, the hematology of blood was studied. The productivity, costs of concentrated feed and energy for the production of 1 kg of milk are estimated, the main physical, chemical and technological properties of milk from the point of view of butter production are studied, the economic efficiency of using silos in the feeding rations of dairy cows is established.
