I would not disagree ,that the course you are taking is the correct one. I was trying to point out that in my opinion it is not the first ,or top priority , when selecting a boar to use on my herd. You would be horrified to look at some of the pedigrees of my Belted Galloways where many breeders positivly believe in keeping things in the family ! A bull may well serve daughters and grand daughters in the belief they are breeding “in ” good traits . Something I would never consider with pigs .
