Effectiveness of using synbiotic in feeding of lactating cows

Cow’s milk is a complex product of animal origin with signifi cant differences noticeable in terms of its nutritional composition and properties. The purpose of the research was to investigate the effectiveness of using the synbiotic Rumibiotic in the rations of lactating cows. The scientific and economic experiment was carried out on three groups of lactating cows selected according to the principle of analogues, taking into account age, body weight, productivity for previous lactation, breed and physiological state. Against the background of feeding the main ration available for all groups of animals, cows of the 2nd experimental group received an additional 10 g/head/day of Rumibiotic additive, and the 3rd experimental group received Rumibiotic 15 g/head/day. The data on the influence of the synbiotic Rumibiotic in the rations of lactating cows on milk productivity, composition and properties of milk have been presented in the article. For 275 days of lactation 4840.0 kg milk was obtained from a cow in the 1st control group, in the 2nd experimental group it was 4977.5 kg or by 137.5 kg and in the 3rd experimental group it was 5167.3 kg or by 327.3 kg more than in the 1st control group. Profi t from the sale of milk in the 1st control group amounted to 116 160 rubles, in the 2nd experimental group it was 119 460 and in the 3rd experimental group it was 124 014 rubles. The diff erence in milk production in experimental animals receiving the feed additive Rumibiotic made it possible in comparison with the analogues of the 1st control group to receive an increase in profi t from the sale of milk in the 2nd experimental group 3129 rubles, and in the 3rd experimental group 7512 rubles. The profi tability level was 29.1 % in the 1st control group, 32.5 % in the 2nd experimental group and 37.3 % in the 3rd experimental group.
