Abstract
The researchers investigated the effect of new probiotic Vetom 1 based on apathogenic bacilli on the biochemical parameters of blood serum, exactly protein, albumins and urea in lactating cows. The experiment was carried out at OOO “Uchkhoz Tulinskoe”. According to the principle of pair-analogues, the researchers arranged a control group and two experimental groups of cows; each group contained 7 cows. The cows of the 1st experimental group were fed with probiotic Vetom 1 dosed 50 mg/kg once a day in the morning before milking; They received Vetom 1 every day during 5 days, then in a day during a month. The cows from the 2nd experimental group received probiotic Vetom 1 dosed 50 mg/kg once a day in the morning before milking, every day during 30 days. The application of the specimen contributed to a decrease in the concentration of total protein in the blood serum within the physiological norm. The aftereffect caused by Vetom 1 when the specimen was applied 5 days every day, then in a day during a month, the authors observed an increase in the concentration of total protein in the blood serum above the physiological standard on the 180 day of application. The similar effect was not observed when Vetom 1 was applied daily. When using Vetom 1, the authors observed a slight increase in the concentration of albumins in the blood serum, both during the period of application and up to 180 days. The specimen contributes to less prominent increase in the concentration of urea in the blood serum in comparison with the control group. Changes in concentrations of albumins and urea occurred within the physiological norm.

Summary
Коровам 1-й опытной группы задавали пробиотический препарат Ветом 1 в дозе 50 мг/кг раз в сутки, утром перед дойкой, 5 суток ежедневно, затем через сутки в течение месяца. Коровам 2-й опытной группы применяли пробиотический препарат Ветом 1 в дозе 50 мг/кг раз в сутки, утром перед дойкой, ежедневно в течение месяца. При применении изучаемого препарата происходило понижение концентрации общего белка в сыворотке крови в пределах физиологической нормы. В период последействия при применении Ветома 1 после 5 суток ежедневно, затем через сутки в течение месяца на 180-е сутки после начала применения препарата регистрировали повышение концентрации общего белка в сыворотке крови выше физиологической нормы. При применении изучаемого препарата происходит менее выраженное повышение концентрации мочевины в сыворотке крови относительно аналогов из контрольной группы.
