[QUOTE="randiliana, post: 668434, member: 2308"] If the problem is selenium, once the shot is given, you should have an almost immediate response to it. I have seen calves that were on death's door recover almost completely within about 3 hours from when the shot of selenium was given. I doubt that running out of mineral for a week would cause serious problems. It could be that the calf's mama just didn't eat the mineral, if it is free choice, that leaves the possibility that the odd cow doesn't eat the stuff. I would consider that to be unlikely, but possible As RR suggested I would consider BVD (providing they don't recover with the selenium shot). It can cause many symptoms and problems. Weak calves and scoury (especially older) calves can definitely be a symptom. Might be an idea to have the weak calves tested for it. Vaccination is the only thing you can do for BVD, and you won't see a benefit til next year. As for losing calves, we seem to lose around 2-3% of our calf crop, usually 2 or 3 in a year out of 100-150 head of cows. Stuff does happen, but, I wouldn't consider it terribly common. You do have to take the good with the bad. [/QUOTE]
