OPTIMIZATION OF DIGESTIVE EXCHANGE IN DAIRY CATS WITH SUBTOXIC DOSE OF NITRATES IN THE RATION

Abstract

This article presents the results of studies that show that in order to intensify the processes of denitrification in the body to cows in whose rations nitrates are present in a sub-toxic dose, the enzyme preparation of protosubtilin G3x at a dose of 0.03 % and vitamin C in a dose of 0, 04 % of the dry matter norm. In dairy cattle of the 3 experimental group, a significant (P> 0.95) increase in the amount of VFA by 1.61 mmol / 100 ml occurred in the contents of the prednis. At the same time, due to activation of the nitrate reductase activity of microflora in the contents of the rumen of animals of the 3 experimental group, the content of acetic acid proved to be significant (P> 0.95) by 4.11 % compared to the control group. With the combined feeding of biologically active preparations in relation to the control group, in the cows of the 3 experimental groups, a significant (P> 0.95) increase in the number of Flavobacterium vitarumen bacteria per 26,000 / ml and a proteinase activity of 3.07 % occurred in the scar’s contents. Moreover, in the cows of the 3 experimental groups, a significant (P> 0.95) increase in the level of ammonia by 2.53 mmol / l occurred with the control of the contents of the prednisals, with a parallel decrease in the content of nitrates - by 53.0 % and nitrites by 54.3 %.
