In the last two calving seasons, we have had trouble with clostridium in some of our new born calves. We give the bovine ecolizer+C20 and first defense at birth, but still have some cases. This year, I am hoping to vaccinate our cow herd with Gaurdian from merk. The cows start calving the end of march. They have not been vaccinated previously, so we need to do the booster as well. Hoping to get the first dose done in the next week. Would of done it sooner, but the weather has been terrible. Am I getting too late? Do any of you use gaurdian? It seems it covers more clostridium preferigens, thus why I am going with it. any advice would be great, I'll do anything to overcome this clostridium crap!!
