Protein concentrates based on extruded lupine grain, with the use of enzymes, in feeding calves and poultry

Abstract

The solution to the food security of the population of any region depends on the creation of its own production of high-protein plant feeds. Protein nutrition issues need to be addressed quickly, both in protein production and in rational use. Unbalanced diets for protein inhibits the growth and development of young animals, disrupts metabolism, increases feed consumption per unit of production, thereby increasing its cost. Under these conditions, the use of non-traditional protein feeds of local production and the creation of new recipes for energy-protein concentrates as full-fledged components of compound feeds has become one of the tasks of the Kaliningrad research Institute of agriculture-a branch of the Federal research center all-Russian Institute of feed named after V. R. Williams.The author has been working on the problem of protein deficiency since 2000. She started at the Federal state unitary enterprise “Novonikolaevskoe” in the Balakovsky district of the Saratov region with scientists from the Department of animal feeding at the Vavilov state agricultural University: doctors of agricultural Sciences Alexander Petrovich Korobov, Sergey Petrovich Moskalenko, Alexey Alekseevich Vasiliev, and continued from 2009 to the present at the Kaliningrad research Institute of agricultural research.The article presents data on feeding calves (2013-2019) and quails (2019) energy-protein concentrate based on extruded grain of narrow-leaved lupine, instead of soy, subjected to heat treatment on a press extruder as part of compound feed; determining the effect of the concentrate on changing the productivity of calves and quails. Calves were fed lupine concentrate with a shell, quails without a shell with the addition of an enzyme preparation.It was found that the feed value of the extruded concentrate based on lupine is not inferior to the extruded concentrate based on soy and allows you to get good gains in live weight of animals and poultry. Concentrate based on lupine, with the addition of enzymes in biological value is equal to full-fat soy.
