Clostridial diseases can challenge the health of a cow herd. And blackleg is one disease that many ranchers often encounter.
Blackleg, a soilborne pathogen, is usually ingested by cattle as they graze on shorter forage. While infectious, it’s not a contagious disease, according to Dr. Bob Judd, host of Texas Vet News on the Texas Farm Bureau (TFB) Radio Network.
When the soil is stirred due to excessive rains, the spores may be released into the environment and can increase exposure.
The bacteria works its way through the bloodstream and is deposited in muscle tissue throughout the animal’s body. Spores lie dormant until stimulated to cause disease and are only activated in a low oxygen environment like damaged or bruised tissue, Judd said.
Judd noted vaccination is critical to disease prevention. He recommends owners vaccinate their calves at four months of age.
