Re: What's in your Manure?

George, I am not a specialist in bovine biology nor even an expert in human biology.  However, I do know that antibiotics in humans are processed by the liver and kidneys, to be excreted in urinary form. I would doubt that any by-products of antibiotic metabolism are in the solid waste. There is the matter of cows urinating and defecating in the same general area. Antibiotics have pretty short half-lives, if the manure sat for a month or two, I wonder if any would still be there.
Still, we all have to make our decisions about what is best.  Just my two cents.
