I have two does (two year old and her 1 yr old daughter) that I am looking to breed. They are Nubian/boer/?/? I really want to incorporate the Nubian genes into my herd but have been unable to find a buck in my area. A friend of a friend just offered to let me breed to his Alpine buck. I have only seen pictures of him, I haven't actually seen the goat. Would that be a good cross for producing milk goats? How does an Alpine compare in size to a Nubian?
