[QUOTE="farmerjan, post: 1498602, member: 25884"] I don't know if they would get blackleg that young....but all our cows are vaccinated for blackleg and they should pass the antibodies down to the calves and they should have some resistance until 6-12 weeks according to our vet. But, bringing in cattle without having any idea of if they had any vaccines would make me do a lepto and a blackleg as soon as they get there. We use killed virus vaccines due to the possibility of pregnancies and I am assuming that he brought these as breds in Dec. I don't want to overwhelm a cows system coming into a new place. Any other vaccines can wait a bit, but these two are pretty much standard for us. There could be other "bugs" there that his own cattle are immune to and these are not. We did have an outbreak of e-coli scours; he called it wet weather scours; years ago, with some of our own calves. Wet rainy weather, just as spring was trying to get going. Found one dead, 3 more very lethargic, one down. Got them to the barn with their mommas, called the vet and he put them on antibiotics. I cannot remember what, it was years ago. But, after a couple of days, with 1 or 2 getting IV's the first day and then electrolytes and mommas milk when they could get up and nurse, we managed to save them. They had dehydrated overnight it seemed. I remember the vet saying that the wet rainy weather, the grass trying to grow and the temps getting very warm then chilling down, were a recipe for e-coli outbreaks, as well as clostridium, and that blackleg vaccination was very important. As soon as they got up and going they got a vaccination, we ran all the cows through the chute and all the healthy calves and gave every one a vaccination shot. It seemed to stop the problem and since then we just do it. Cheap to do and if you save one calf, then it's paid for. Cows were trying to graze the little green shoots that were trying to grow and we had alot of clover in that field too.... I can't remember if there is a vaccine for e-coli...
