I CURRENTLY don't wean at all... let the cow do it. And I do have some that are nursing both last years and this years calf at times, but for the most part, they "self-wean" them. I however do think it's better to wean the calves off, so that they're not feeding two. Haven't had trouble though with breeding back... You breed them well before you wean the calf off of them, so its not going to affect their fertility there. That does affect some species though, and some more than others. So if within those species, you used selective breeding, you could select for the genetics you found desireable. (Within the human population, nursing "can" suppress the ovulation cycle, for example, and be used somewhat as a natural form of conception control).
