PARAMETERS OF RUMEN DIGESTION IN YOUNG CATTLE AGED 6-9 MONTHS WITH THE USE OF EXTRUDED HIGH PROTEIN CONCENTRATED FEEDS

Abstract

The paper presents the results of studies aimed at determining correlation of rumen digestion parameters in young cattle aged 6-9 months with the use of extruded high-protein concentrated feeds. It was determined that protein of extruded grain is more efficiently used for synthesis of microbial protein compared to ground grain due to reduction of degradability in the rumen by 8-11%. Extruded field pea grain instead of ground one in diets for young cattle at the age of 6-9 months helps to increase efficiency of feed. The average daily weight gain is increased by 4.1-5.6% compared with coevals fed with ground grain. As a result, the feed cost for obtaining weight gain is reduced by 2.8-4.7%, protein - by 2.6-4.3%.
