The article considers the features of the chemical composition and feed intensity of broad-browed cornflowers (Elytrigia elongata) as one of the most promising perennial fodder crops in arid regions[1]. The analysis of the content of crude protein, fiber, fat, nitrogen-free extractives, ash and basic macronutrients depending on the phase of plant development is carried out. It is shown that the granary is able to form stable yields of green mass and hay, and the forage capacity of crops reaches 1600-2400 fodder units per 1 hectare. High adaptability and resistance to drought make the broad-browed breadbasket a valuable component of the forage base in conditions of limited moisture[2]. The indicators of energy value are determined: feed units, exchange energy and digestibility of nutrients. The data obtained confirm the expediency of widespread introduction of broad-browed granary into forage production in regions with insufficient moisture, since the crop ensures stable feed quality, high productivity and durability of the herbage. It was found that the protein content decreases in the direction from the tillering phase to the earing phase, while the proportion of fiber increases naturally [3]. The mineral composition is characterized by a high content of calcium, magnesium and macronutrients necessary for animal resistance to stress factors.
