I have one Nigerian dwarf doe and an Ober. I haven't gotton to milk my Nigi yet as she was dry when I got her and I am just now breeding her this month. My other goat is an Oberhaslis. She is on the small side. She puts out a decent amount of milk and she is not a whole lot bigger than the Stud Nigi I have over here. Oberhaslis are of the Small/ Med sized variety of Diary goats, where Nubian and alpines are on the Med/ Large scale. They are kinda bossy and leaders of the pack but they put out ALOT of milk for thier size when lactating. Like anything some of them are smaller or larger than others, i think mine runs the Smaller scale. I am going to breed my Ober to the Nigi buck also and hopefully come out with Mini/ small milk goats that are not much larger than Nigis but have a little more milk. I already have takers for these babies. Oh and I plan to make soap, Mozerella cheese and yogurt for a start.. Hope this helps.
