While walking down the supplement isle at WalMart looking for Melatonin, I noticed that they carry selenium. I didn't notice what the mg/mcg was but in a pinch can this be used along with vitamin E and B Complex, instead of BOSE? My vet will only give my goats whatever is needed at the time of the $57 office visit. He refuses to give me anything to keep as a preventive or a just in case measure. He insists he must see the animal BEFORE he prescribes ANYTHING. He doesn't trust anyone to know whats better for their animals than he does. Hes also the ONLY vet around that treats goats. Right now my goats are happy and healthy but the doe may be pregnant.
