so am I. Seems there's something missing in this communication lol
You asked if I was using it, I'm not sure why?
But it does say on the bag (of medicated chick starter, Purina) "when immunity is not desired"
Next time I'm at the feed store I'll have to take a picture of the bag.
Maybe it's just a CYA type thing.
I don't know about purina. I buy a 20 kg bag each month and mine simply says ' contains avatec as an aid in the prevention of coccidiosis.
Protein 20%
Calcium 1.2%
Lasalocid sodium (avatec) 90 mg/ kg.
