According to the Meat Animal Research Center, Gelbvieh is the only breed
that reduced mature cow size in its germplasm study between 1973 and 2004.
Crossbreeding with Gelbvieh results in cows that are 30% more productive
over their lifetime due to increased fertility , weaning weights, and cow
longevity. MARC data shows crossbred cows stay in the herd an average of
1.9 years longer, reducing replacement cost.
most recent MARC evaluation, Gelbvieh sired calves had the lowest birth
weights of the four major continentals and tied for the top survivability
to weaning of all breeds.
