Clostridium perfringens is the most important cause of clostridial enertitic disease in calves. During one calendar year at one dairy farm we isolated Clostridium perfringens type B from calves during suckling period. Purpose of our research was to find the most appropriate therapy for that particular farm. It has been found statistically significant differences (p is less than 0.01) between clinical cases in calves within first six months of the year (20) in comparison with the number of calves with symptoms of enterotoxemia in second half of the year (41). Also, statistically significant differences were observed as far as season was concerned. In the autumn/winter season incidence 47 sick calves were observed in comparison with spring/summer season when 14 animals became sick. It has not been found statistically significant difference (p is greater than 0.05) among two groups as far as mortality was concerned. Average age of the animals with symptoms were 71.63+/-8.21 days. Average age for fatal cases were 77.25+/-16.39 days. Average duration of the therapy was 6 days.
