Scientific and practical recommendations for obtaining innovative feed based on a three-component poly-species mixture of annual forage crops

Long-term studies (2000-2020) showed that the introduction of vetch-oats grain silo mixture in the diet of dairy cows contributed to an increase in milk productivity by 6.1 %, while reducing the cost of exchange energy for the formation of 1 kg of milk by 1.7 %. The aim of the research was to obtain an innovative feed for dairy cows based on the use of a variety mixture of annual forage crops, from which grain silo mixture can be produced. To achieve the goal the following tasks were solved: field and laboratory studies were carried out to achieve the intended result; production experience was carried out on the use of grain silo from poly-species mixtures of annual forage crops in the feeding of dairy cows in the conditions of “Vozrozhdenie OAO”(Open Joint -stock Company) in the Vitebsk region. The obtained data were used for analysis, interpretation and subsequent implementation in large-scale specialized agricultural production. As a result of the conducted research new agrotechnological opportunities for obtaining higher production and economic indicators were established. The main problem factors of obtaining a highly effective feed mixture and methodological approaches to their solution were the main ideas running through the entire presented work at the same time. In general the presented research results showed the ways and possibilities of conducting intensive feed production with the implementation of a very important and complex task to provide livestock with high-quality cheap feed based on obtaining plant feed of their own production (in the conditions of an agricultural enterprise). Production studies and calculations showed that the cost of cultivation and harvesting of cereal-legume mixtures per grain silo per 1 ha of crops was 55.7 conventional units (3899.0 rubles). RUS), at a silo of dried grasses - 4587.0 rubles. RUS, the total economic effect in the form of revealing hidden on-farm production reserved is 688.0 rubles/ha.
