Studing of the composition of plant raw materials for the development of a recipe for a new type of feed

Abstract

The article examines the chemical composition of some types of grain crops – wheat, bran, barley to identify the most nutritious of them, mixed with a feed additive to obtain highly nutritious feed for cattle. According to laboratory studies, the selected raw materials exceed the most common types of feed in terms of mineral content. Bran has the best indicators of vitamin and mineral composition, but the content of fiber and ash in them is higher than in wheat and barley, which can negatively affect the digestibility of ruminants. Wheat has the lowest indicators in terms of the content of the mass fraction of fiber and ash: fiber – 10.44%, ash – 1.57%. The content of the mass fraction of fat in the studied raw materials is in the range of 2.13-3.62%. Consequently, 3.5-4% of animals or a mixture of animal and vegetable fats protected from decay in the rumen can be added to the cow's diet. Comparing the data obtained with the minimum requirements for fodder crops and feed quality in the production of milk and beef, the compliance of the actual results with the requirements of regulatory documents was revealed. Based on the data obtained, it is concluded that it is possible to use this raw material as the main raw material for the development of compound feed with increased nutritional value.
