I just checked and my oyster shell has some parts of the shell glow under my black light. So there are other things that could be in feed that would cause the feed to show bits glowing anyway. Sure doesn't make it easy... The idea of mixing our own food seems so daunting. I really hope I don't have to.![]()
I recall from my mycology class that aflatoxin is visible under black light. But with 50 parts per billion having an affect on ducks, I don't imagine it would be detectable by the time it is mixed into feed. . . . .
Well, so, time to revive some of the threads with homemade duck feed recipes? Picture me taking a few deep breaths and resting my head in my hands for a few minutes to process the implications here . . . . Lord, have mercy.
