Boehringer Ingelheim Vetmedica, Inc. offers three clostridial vaccine lines to fit producer needs. Alpha-7® is the only 2 mL single-dose, seven-way clostridial vaccine on the market for blackleg. Alpha-CD™ is a one-dose vaccine that aids in protection to help reduce enterotoxemia.

The Caliber® vaccine line requires two 2 mL doses. The Bar-Vac® family includes more traditional clostridial vaccines that requires a 5 mL dose, plus a booster three to four weeks after initial vaccination, but it offers combinations to address specific problems.

“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.”
