Sorry to ask yet another copper questions, but I have been reading through all the copper threads I can find and still have a few questions I am hoping you all can answer for me! Turns out my Nubian, who is scheduled to be bred this month to a handsome LaMancha buck, is developing a fish tail. She is a black goat with a tan skirt so I have never really looked for a reddening of her coat as it sort of blends in to the tan anyway. I understand, however, that copper deficiency can affect her fertility as well as her ability to carry kids to term. In either case, she has access to a loose mineral but I am pretty sure she never uses it - she certainly never licks at it when I offer it to her! I am not really sure how to progress as I am leary of bolusing and from the reading I have done on this board, the copper sulfate alternative sounds equally as freaky. Is it possible to have her copper levels tested with a blood test to determine how deficient she is? Is there a mineral I can order on-line that she might prefer that has a high copper value? We are not in a copper deficient area, but she hasn't been getting grain since she is dry and not bred yet. Could this be contributing to it? Any and all advice is appreciated!
