[QUOTE="Sandpit Farm, post: 7645567, member: 1646"] It is not a load of rubbish but you'd be right that many farmers aren't maximising the genetic potential they already have. The difficulty is that many people make their breeding decisions based on the performance they experience on farm. So for example, breeding for lower cell counts because you are in the midst of a cell count issue is pointless as it is likely to be an environmental problem rather than a genetic one. That is why it is important to know the genetic weaknesses in your herd so you can use semen from a bull that compliments it. Also, it is important to know the herd you are aiming for and breed for those traits. Production is just one tiny piece of the puzzle. If you think of the genetic potential of a cow as a glass and her performance as the proportion of water in that glass.... if you breed a bigger glass that is a quarter full, the performance is better than a smaller glass that is a quarter full if you see what I mean.
