[QUOTE="KNERSIE, post: 387874, member: 4353"] George, I am like dun on this one, I would choose neither of the two, but my reasoning is somewhat different. I prefer a WW of around breed average or slightly above as I don't want to be left behind when it comes to growth up to weaning age. When it comes to the YW I prefer slightly below breed average, but definately don't want any animal with a YW EPD significantly higher than the breed average. My reasoning behind this lunacy is that I want to breed early maturing animals that grow quickly without increasing frame size or rather without the risk of frame creep. With the EBVs we use we also have a 540 day weight, I take the spread in the growth into account more than the actual numbers, I don't want the jump from ww-yw-540day weight to be too drastic as this is often an indication of later maturity. In an ideal world my EBV spread for growth would be something like this. average BW, slightly above average WW, average YW, below average 540d weight. But after all this is said and done, EBVs play second fiddle to my eye and the phenotype I desire for my conditions. I have seen too often that less ideal animals with very good EBVs perform poorer than more ideal types with very ordinary EBVs. [/QUOTE]
