No Mam, Surechamp pellets are fed at a rate of 1lb per head/day...
As far as joints and protein, I don't know anything about your animal or its structure, but I have fed Oxy and Surechamp at the same time without issues. I will start the combo for 30 days on all my calves when I first bring them into the barn for halter breaking. After that I keep them on Surechamp until we stop showing them...G-Luck
