Scientific and economic trials were carried out to test the prophylactic effect of the preparation Bulgarben in calves affected with digestive troubles. Bulgarben was given in the first 10 days after birth at the rate of 100(3) daily of a 12.5 per cent suspension formula activated in one of the milk rations of the animals. The investigations were effected on six farms of the country with a total of 622 test and 586 control calves. The economic analyses of the results showed that with the use of the preparation the number of occasional outbreaks was reduced to 19.9 per cent with the test animals, while it was as high as 42.5 per cent with the control ones. With the test calves mortality rate dropped to 1.6 per cent, and with the controls it was 4.94 per cent. The amount of drugs used with the test animals was three times lower than that used with the untreated controls for the whole experimental period. It was found that the preparation produces a good prophylactic effect in the case of digestive troubles in calves.
开展了科学和经济试验，以测试制剂保加苯对患有消化问题的犊牛的预防效果。保加苯在犊牛出生后的头10天内给药，以动物一份乳日粮中12.5%悬浮液配方100(3)的日剂量给药。在该国的六个农场进行了调查，共有622头试验犊牛和586头对照犊牛。结果的经济分析表明，使用该制剂后，试验动物偶发疫情的数量降至19.9%，而对照动物则高达42.5%。试验犊牛的死亡率降至1.6%，对照犊牛的死亡率为4.94%。在整个试验期内，试验动物使用的药物量比未处理的对照动物低三倍。结果发现，该制剂对犊牛消化问题具有良好的预防效果。
