Conclusion
Ask yourself what traits am I being paid for? What traits save
me money? Then consider EBV’s, but never lose sight of the need
for visually appealing cattle and a focus on time tested cattle breeding
fundamentals (eg herd wide calving ease). EBV’s are useful, but
perhaps their popularity has reached the point of excess, and the industry
needs to stop paying lip service to things like structure and doing ability
and actually apply these old fashioned principles to their business as
a higher priority than Breedplan.
If you like the look of the bull and his EBV’s are OK, then that
bull is suitable for you. It is pedantic to concentrate on minor numeric
deviations in unproven bulls for commercial use. As stated at the outset,
EBV’s are just the best estimate at the time. In two year old bulls
and younger, the only guarantee that can be made is that their EBV’s
will change as time passes.
