Profit-driver importance (%) for breeding:
This blue bar-graph shows the relative importance of the underlying genetic profit-drivers for the commercial use of Simmentals when daughters are retained for breeding. This reflects both the economic effect of changing each profit-driver and the amount of opportunity there is to genetically change them. Joining is to British breed cows where there is only a modest concern about calving difficulty. Steers are finished at pasture to produce a 300 kg carcase at 16 months.
