Консервирование бобовых трав и бобово-злаковых травосмесей с новым биологическим препаратом

Abstract

The results of testing a domestic experimental biological additive on perennial legume grasses are pre-sented in this article. High-quality silage was obtained with new preparation on active acidity, content and ratio of organic acids, ammonia, parameters of nutrient losses. The optimal dose of application was de-termined: at ensiling the basic types of legumes — 80 ml/t, for forage galega — 100 ml/t. Under scientific and production conditions the experimental biological additive was used for ensiling alfalfa-gramineous grass mixture, that was non-ensiling raw material. The enzyme-bacterial additive Acidphast NC GOLD, produced by ''Lallemand'' Company, and the Finnish chemical preparation AIV 3 PLUS were used as the controls. The high quality of silage with a new additive was revealed on the basic organoleptic and bio-chemical parameters in comparison to feed, prepared with biological additive Acidphast NC GOLD. Then the nutritional value of obtained silage in each variant was determined in physiological experiments at feeding Romanov`s rams-valukhi when used as the only feed with addition of mineral supplements. A higher digestibility of crude fiber and fat in feeds with biological additives was found. The energy nutri-tional value of the silage with the experimental additive was 9.6 MJ metabolizable energy per 1 kg of dry matter versus 9.5 and 9.4 in feeds, prepared with Acidphast NC GOLD and chemical preservative AIV 3 PLUS respectively. Our investigations proved the high effectiveness of the experimental sample of new enzyme-bacterial additive at preservation of different species of legume grasses.
