Improvement of the consuming properties of the cheese «Osetinskii» at denitrification

Efficiency of applying preparations epophen and chelatone possessing adsorption properties in the cows ration with the aim to detoxicate nitrates and nitrites was studied in the course of experimental work. For the purpose four groups of animals of the Schwyz breed (ten cows in the group) were formed by the principle of the pares-analogues taking into account breed, live weight, date of the last insemination, productivity and milk fat level during the last lactation. The experiment was carried out for 305 days. No considerable differences in the milk yields with the natural fat level received from the control group (4147 kg) and from the trial group (4165-4252) in the course of lactation were established. Cow milk density was 27,71 °A at total solids content 12,15 %. The milk produced by the trial group was characterized by increased levels of the vitamin A by 49,86 % and the vitamin C by 53,80 %. The highest levels of fat and proteins as compared with the control were determined in the milk of the third group of cows and were by 0,19 and 0,20 % higher respectively. The milk produced by the cows of the third group was also characterized by increased levels of alpha-caseine by 3,88 % and simultaneous reduction of gamma-caseine by 3,73 %. The diameter of the caseine micelles in the milk of the third group was by 16,6 % higher than in the control. Nitrates and nitrites levels in the cheese samples made of the milk of the third group were by 72,19 % and 76,71 % lower respectively as compared with the control cheese samples.
