With only 3% of the US dairy cow population certified organic, the majority of data underlying national genetic evaluations come from conventionally managed cows. As a result, if the differences in an environment that an...

With high feed costs, improving whole-farm feed efficiency is crucial for maximizing herd profitability. The most important metric for determining your herd’s whole-farm feed efficiency is feed cost per hundredweight of energy-corrected milk sold.
Data from the...

To aid in the understanding of sire proofs for type traits and their relationship with the expected average daughter classification scores in first lactation, Lactanet created interpretation tables for all seven breeds.
The updated tables...

Linear type trait genetic evaluations are first calculated as Predicted Transmitting Abilities (PTAs) similar to the production traits and final score. PTAs for different traits (such as PTA Milk and PTA Protein) expressed in the...
