Nutrition of winter intermediate crops depending on technological factors of cultivation

Abstract

One of the main components of the successful management of the livestock industry is the use of traditional and less common forage crops in the feed conveyor links, different in the rate of green mass growth and balanced in the protein content. Annual fodder plants, including winter triticale, play a significant role in the system of such a conveyor. Field research was conducted at the Agronomic Research Station of the National University of Life and Environmental Sciences of Ukraine on typical low-humus chernozems. The object of research was winter crops: wheat (control), rye (control) and triticale (early ripening variety AD44, mid-ripening variety Polissky 29, late ripening variety ADM 11), sown in five calendar dates. It has been established that sowing winter triticale at the most optimal time, in accordance with the biological requirements of varieties, allows not only to control the production process in crops, but also to control the quality and nutritional value of the fodder mass. Due to their properties to synthesize proteins and carbohydrates, an important zootechnical characteristic of plants is their ability to provide high foliage of the aboveground mass. Among the studied varieties of winter triticale, the maximum leafiness was provided by the variety Polisskiy 29–34.2–35.3 %. Depending on the time of sowing and variety, mowing the vegetative mass of triticale in the earing phase provides a yield of 3.22–8.23 t / hectare of feed units and 0.39–1.07 t / hectare of digestible protein. The supply of feed unit protein was 114–132 g / feed units
