My background before kids was in animal sciences, also worked on a pig
farm and with dairy cattle. You are right, from what I remember in the
pig department the first born always went for the teats close to the
front. The last born ended up with the teat at the back. If it was a
small litter, less than 8-10, not usually a problem. With a big litter,
more than 12 or so, there might be a problem with the last piggies born
doing well. The teat they latched onto the first time was the one they
stayed with.

One of the characteristics used to decide whether to keep a pig for
breeding was the number of teats she had, although the ones close to the
back were often not counted because they never seemed to produce much.

Entertaining discussion, finally something I feel knowledgeable about.
