[QUOTE="dun, post: 568829, member: 34"] I don;t know, but in crossbreeding if you breed one half of an F1 back to one of the parent breeds you will lose some size, repeatedly breeding back to that same breed in theory decreases it more. I've seen the breeding back deal decease the size of the offspring but don;t really know if it's the breed regression thing or because we've selected more moderate framed bulls. The vet bred 3 or 4 generations of EXT daughters back to EXT and the last generation heifer was a tiny little dink. [/QUOTE]
