Experiments were carried out with a total of 23 calves aged 1 to 10 days, divided into two groups. The animals of the first group were prophylactically treated in the course of 10 days against digestive troubles, being given the preparation Bulgarben with the milk at the rate of 100 cm3 each. The animals of the second group served as controls. Followed up were the morbidity rate and the changes taking place in some biochemical and hematological indices--Ca, Mg, P, total protein and protein fractions in the blood serum, Na and K in the plasma and erythrocytes, hemoglobin content, hematocrit value, total leukocyte count, and differential blood picture. It was found that Bulgarben in the from of a 12.5 per cent suspension BA, at 100 cm3, did not bring about any changes in the indices studied. Certain drop of the Mg level in the serum of the test calves to the low limits of the normal value was found, which makes it necessary to follow up the Mg content in the serum at continuous application.
对总共23头1至10日龄的小牛进行了实验，将其分为两组。第一组动物在10天内接受预防消化系统疾病的治疗，以每100立方厘米牛奶添加制剂保加本的方式给药。第二组动物作为对照。对发病率以及一些生化和血液学指标的变化进行了跟踪观察，这些指标包括血清中的钙、镁、磷、总蛋白和蛋白组分，血浆和红细胞中的钠和钾，血红蛋白含量、血细胞比容值、白细胞总数以及血液分类计数。结果发现，100立方厘米12.5%悬浮液BA形式的保加本并未使所研究的指标发生任何变化。在试验小牛的血清中发现镁水平有一定程度下降至正常值下限，这使得在持续应用时必须跟踪血清中的镁含量。
