The use of silos from legume-cereal grass mixtures and energy feed additives in the feeding rations of new-bodied first-calf cows

Abstract

The paper presents a technology for obtaining dried silos prepared from herbs of legume-cereal mixtures, which ensures maximum preservation of nutrients and high quality of feed. The chemical composition and nutritional content of feed, the norms for the introduction of tested silos into the main feeding diet, and the dose for the introduction of an energy feed additive were determined. Based on the balance sheet experience, the digestibility of the main nutrients was calculated, the hematological and biochemical status of blood was revealed, the productivity and quality of first-calf milk was estimated, and feed costs for the production of 1 kg of milk were established.

“…Vegetable sources of protein (legumes, oil crop cakes and meal) are rich sources of lipids and energy, but they are significantly inferior to animal feed in terms of the content of non-cleavable protein [3,6,12,13,15].…”
