Could someone please tell me what calf manna is? I have seen it mentioned so many times. And the other question is, when you give Ivomec orally is it still good for lice or do you have to use something else? Wendy
Website for Calf Manna - http://www.mannapro.com/calf-manna.htm Basically, it's a pelletized supplement feed. Someone mentioned earlier that it's soybean and whey based.
