title: [Bulgarian potassium-calcium zeolite in the prophylaxis of digestive tract disorders in calves].
abstract: Scientific and economic trials were carried out to test the prophylactic effect of Bulgarian K-Ca zeolite products in the prevention of digestive troubles in calves, corresponding to the State Standard production branch requirements of 33675789-79, and to 0.00-0.01 mm (France). When applied at the rate of 2 per cent constituent of the daily milk ration from the first to the fifteenth day after calving it was found to produce a good prophylactic effect against digestive disturbances. It was also found that there was enhancement of the general resistance in calves. This resulted in lower morbidity and mortality rates, and shortening the period of illness in calves that received zeolite. By the end of the experimental period there was a definite rise of the blood albumins, the sum total of the gamma-globulins, the hemoglobin value, and the absolute values of granulocytes and lymphocytes.
