Just wanted to post a follow up. We did boosters today, so now everybody is vaccinated. I have to tell you it feels good, I feel like we have taken that extra step to protect them. We also taped them all and measured heights. Last, I asked my vet about Multimin 90 and he said that he was skeptical, but that he and a dairy that we works with ran an experiment. They gave half the herd Multimin 4 weeks prior to breeding, and the other half just normal loose mineral mix. The half that received Multimin had a 30% higher conception rate. So, we gave them a dose of Multimin 90 while we were at it today.

If I gave my heifer her first vaccinations and boosters last November (when she was about 6 months old), should I give her a booster when the cows get their annual booster in May, or wait until May 2017?

Dave -
Most killed vaccines require an initial vaccination, then a booster vaccination 4-6 weeks later. That's for a calf, so they have received initial and booster vaccination, prior to weaning. It's usually a good idea to give another round of booster vaccinations, called "pre-breeding vaccinations", approximately 4-6 weeks before the breeding season starts.

This isn't really what you were asking, Dave, but it does relate to the question of how long to go between vaccinations. We give our cattle rabies vaccinations (in addition to the regular cattle vaccines) because we get possums and raccoons here, and Dexters are curious. (A couple years ago a llama in our area got rabies and had to be put down, but it had already spit on several people, who had to get the rabies shots. Plus people let their unvaccinated dogs roam, and we have a 300+ acre hunting preserve full of wildlife on two sides of us.)
A few years ago the vet I was using gave our cattle a rabies vaccine that he said lasts for three years. So last time we did vaccines, I brought it up to the vet we use now. He told me there was a study done that measured rabies titers on horses which found that within a year of the vaccination date, the titer was so low that it afforded no protection. Maybe the other vaccines have a bit more longevity, but I thought that was interesting to know.

Vaccination boosters should also be given sufficiently ahead of time, prior to anticipated stressful events such as weaning, transport/movement, exhibition/fairs, severe winter weather, and/or exposure to other herds. Any time the disease exposure risks increase significantly, booster vaccinations can be done to help assure heightened immune response in case of exposure. That's why they will give you a tetanus booster shot, even if you were vaccinated for tetanus in the past 5 years, when you have a puncture wound and go to the doctor. Vaccinations do not guarantee sufficient immunity, but if vaccinations are done properly, and booster vaccinations are given in a timely manner, this assists the development of strong immune response to specific diseases that cattle are commonly exposed to.

I have heard of Angus owners in our area that have had a nightmare time with blackleg, and it got me thinking that I have never heard of a Dexter owner saying they have had a problem with blackleg in their herd...anyone know of any?

Lynne, while I don't know of any specific cases of Dexters contracting blackleg, it seems to not be related to breed. Many Dexter owners do not vaccinate; they also may not investigate the cause of death if an animal dies on their property. Here's a fairly thorough article on it and other clostridial diseases: www.drovers.com/article/blackleg-and-other-clostridial-diseases-cattleHope this is helpful. Gale
