Enzymes produced by the digestive tract of ruminants are unable to digest cellulose. Nevertheless, a large amount of fiber in the feed used by ruminants is broken down by the action of enzymes of the rumen microflora. This complex process not only destroys the fibrous material, but also releases the nutrients contained inside the cells, so that the digestive juices of the animal can more easily affect them. For experimental studies, 2 experimental groups were formed: the bull-calves of group I included mechanically ground sunflower husk in the diet, group II - sunflower husk fermented for 9 days in a bioreactor, at T = 39°C, pH = 6.9-7.0. Husk was introduced into the diet of bull-calves of groups I and II together with a concentrated part of the feed, replacing 10% by volume. The object of the study are bull-calves of the Kazakh white-headed breed with chronic rumen fistula, with an average weight of 340-345 kg, aged 15-16 months.
