All but two areas of the United States are selenium deficient. One of the areas that has plenty is an old mine, where there is too much. Selenium is in the soil from the ice age and travels via flooding. If an area has been farmed, it is more than likely deficient (the Federal government will NOT allow farmers the freedom of adding enough back to the soil to matter). I didn't buy into to all of the vaccinations at first either, I researched cause and effect, and found BoSE to be one of the MOST IMPORTANT vaccinations you can give your goats. So take it for what it's worth, call it a fad, just like goats were a "fad" 10 years ago. They weren't, but that is what they were called. And BTW, I have had necropsys done, and I have put out the money to have lab testing done, my statements are the result of both personal experience and scientific study.
Cutiepieactes, your area is deficient as is the soil in surrounding areas, I've been there, I know. You may have gotten away with not doing the work of vaccinating, but that doesn't mean you goats have gotten the best care possible. Science matters, and before dissing a program, you might want to do the research necessary to support your position.
