[QUOTE="KNERSIE, post: 618533, member: 4353"] You can't measure efficiency of feed convertion in the entire cow herd, but by using bulls that was tested for feed convertion rate and by doing your own extensive on farm growth tests where you grow heifers out on your natural grazing plus a little supplement if needed you can identify those who fare best under your conditions. The reason for the supplement isn't to disguise the poorer doers, but rather to make this a growth test and not simply a survival test. Off course this is more applicable if you run your cows on natural rangeland or veld, but the adaptability and ability to thrive under your conditions are also more important if you don't have improved pastures. Don't you have bull growth tests where the intake is measured in the USA? [/QUOTE]
