Hello! I have a herd of Boer does and a buck. They all look kind of skinny and bony. Especially around their hip and tail bones. Some of the does just kidded about 5 weeks ago. I figured that it’s a mineral or vitamin deficiency of some sort. They are on pasture and meat goat feed, with hay and alfalfa. I’ve heard that some minerals have to be given with vitamin E. Is this true? I’m new to goats so any help with what kinds of minerals and vitamins to give would be greatly appreciated!!
