The use of ferment preparations to increase the defensive functions and to decrease the stress influence on calves

Yu. Shchepetilnikov

As a result of the studies, it was found that feeding calves with fodder enzyme preparations "Proxy" and "Respect" from 30 to 90 days of age in the composition of feed and contained under the conditions of the maximum permissible technological regime (GDTR) contributes to an increase in their live weight by 9, 9% and 10.2%, the intensity of their growth by 6% and 6.4%, gross growth - by 6.9% (p≤0.05). Enrichment of compound feed with enzymatic additives promoted an increase in the morphological and protein composition of the blood, as well as stimulation of cellular and humoral factors of nonspecific natural resistance of the body and a decrease in stress effects in calves.
