DairyTalk 213: High TPI Does Not Mean High Milk Yield - by Helmut Demmelhuber

The TPI index has fundamentally changed. High scores no longer
reflect maximum milk volume, but rather profitability, valuable
milk components, and long-lasting, healthy cows. Using the bull
HOORAY as an example, this DairyTalk episode explains why fat and
protein yield, along with overall system efficiency, now define
top genetics. Misreading TPI as a milk-volume index can lead to
costly breeding mistakes. Success depends on aligning genetics
with the specific goals of each dairy operation. For more
