Кормовая ценность зерна яровой тритикале сортов Ботаническая 4 и Тимирязевская 42

Abstract

Laboratory analysis of raw materials (grains) is an important stage for the production of feed. The wider the range of data obtained as a result of research, the more effective the work on compiling the diet of animals, which is reflected in the conversion of feed and the economic component of livestock production. The use of near infrared radiation (NIRS) technology to determine the nutritional value of feed allows us to obtain data on the content of dry matter, crude protein, crude ash, crude fat, sugar and starch in feed, as well as data on protein absorption in the intestines of many animal species, including lactating cows. With the help of such a study conducted in the laboratory of Eurofins Agro (Wageningen, the Netherlands), data on the nutritional value of grain of two varieties of spring triticale obtained in the conditions of the Moscow region were obtained. The crude protein content in the grain of the Timiryazevskaya 42 variety was 119 g/kg of dry matter, in the grain of the Botanicheskaya 4 variety 125 g/kg of dry matter. In terms of starch content, Timiryazevskaya 42 grain exceeded Botanicheskaya 4 grain by 27 g/kg of dry matter. At the same time, studies have shown similar values in terms of the content of feed units for milk production (VEM) at the level of 1192–1189 g/kg of dry matter, the amount of protein absorbed in the intestine (DVE) — 95–96 g/kg of dry matter and organic matter fermented in the rumen (FOS) — 771–769 g/kg of dry matter.
