We have had several reports of Blackleg in calves this fall with moderate calf losses. Blackleg is a common cattle disease, caused by a soil borne bacterium, Clostridium Chauvei. One of the challenges of the disease is that it occurs very rapidly with little or no warning until losses start to occur.
Animals die with little or no warning.
Blackleg occurs in all areas of Manitoba, and new outbreaks are reported every year. Just because Blackleg has not occurred in an area does not mean producers should relax. As Blackleg is a soil borne disease, it can be spread in many ways including wind, water, wild animals, etc. Symptoms Blackleg is common in the warmer months of the year, usually affecting young cattle on pasture. Calves and yearlings are most commonly affected, with animals often found dead with little or no prior symptoms.
