Zinc oxide is indeed a fine ingredient. It would hardly be an overstatement to say that without zinc oxide to control post-weaning diarrheas, the recent ban on antibiotics might have not been so successful in many countries. Yet, zinc oxide is currently under severe regulation and it is practically banned in many places around the globe, with more to follow suit soon.
So, we need an alternative to it, and we need it now! In my experience, non-zinc compounds, such as acids, probiotics, essential oils, etc., might have a merit of their own but they have not been able to fully and truly replace zinc oxide. So, we’re left with zinc-containing compounds as the only potential true replacements.
Here the story is a bit unclear too. Certainly, we have claims that organic zinc, tetra-basic zinc chloride, protected zinc oxide, nanozinc oxide, and enhanced surface zinc oxide can replace the traditional form of zinc oxide. I have had considerable experiences with some of them, and of course, with zinc oxide.
I would be interested to know your thoughts on these zinc-containing compounds and any others you might know of being of help in replacing zinc oxide!
