We have been watching Holstein cows getting larger, heavier, and taller under the influence of the show ring for some 40 to 50 years. If we are to choose a new direction today in selection goals, I believe it will be to reduce size. It is time we stopped selecting for larger and taller cows. As an alternative, we may simply begin by paying absolutely no attention at all to size and stature. If we wish to move more rapidly we may actually discount larger cows in the selection process and this will give an advantage to the medium-sized cow.
Big cows cost a lot to keep.
They don't fit into an average size conventional or free stall. We are definitely heading for the commercial era, and big cows will not fit in that era. Why not start breeding for a standard, medium sized cow. If, just by chance, you get a big one that is also pretty, you can move her from your commercial herd to the first show ring jockey that walks into your barn and is ready to pay a premium. Maintenance costs on large cows are substantially higher than those on medium sized cows.
