Reducing Herd Losses to Blackleg
Early protection against diseases caused by clostridials helps protect bottom line
In many cases, death is the first sign of clostridial diseases to appear; by the time the disease can be identified, it's often too late. Most cow/calf producers are familiar with blackleg, but it is just one of several clostridial diseases that can cause significant losses for beef producers. Clostridial diseases are highly pathogenic and can affect cattle quickly. It's important to vaccinate to keep cows and calves safe from these hard-to-control spores.
Clostridia are anaerobic spores, which allow the bacteria to live in the soil for long periods of time. There are two ways for cattle to contract clostridial disease: ingestion of the spores, or through open wounds that allow the spores to enter.
Clostridial diseases that challenge the herd
Producers in the Northern Plains face significant threats from blackleg and enterotoxemia. According to Dr. Jerry Woodruff, Professional Services Veterinarian with Boehringer Ingelheim Vetmedica, Inc., all ages and classes of cattle are vulnerable to these diseases, but young animals are the most vulnerable.
"Young animals, especially those that have not been vaccinated, are uniquely vulnerable to threats from clostridial diseases," he says. "Getting the vaccination program started just after birth is a great way to protect the health of the calf, and of the rest of the herd."
Dr. Woodruff says that the best way to stop clostridial diseases is to protect the animal before infection sets in. "Prevention of clostridial disease is critical because once clinical signs appear, treatment isn't always effective," he says. "Clostridial diseases are highly pathogenic; to prevent an outbreak, I recommend vaccinating calves early — before they go to grass."
Fight back with a sound vaccination program
"In the Northern Plains, it has become common to vaccinate calves with the 7-way vaccine at birth or shortly thereafter," Dr. Woodruff says. "Since producers are handling calves a lot at this time, it makes sense to vaccinate at those touch points."
In addition to opportunities to vaccinate at birth, Dr. Woodruff notes that producers should also consider vaccinating for blackleg at branding time or turnout.
Dr. Woodruff recommends that beef producers work with their herd veterinarian to identify the clostridial species most common in their region. He says it is important to select a clostridial vaccine that fits their management program and the disease challenges for the area.
"If you lose one calf in today's market, you could have paid for a lot of clostridial vaccine," Dr. Woodruff says. "Prevention of clostridial disease through vaccination is the key to success."
