ABSTRACT
Genomic selection increases accuracy and decreases generation interval, accelerating genetic changes in populations. Assumptions of genetic improvement must be addressed to quantify the magnitude and direction of change. Genetic trends of US dairy cattle breeds...
As a land-grant university, we often work to understand and explain farmer behavior. Every four years, we look at farmer buying behavior, with the next study set for January. We also explore other issues important to agribusinesses who serve...

Highlights
Lifetime costs and revenues are important to identify profitable cows.
Culling decisions are mostly based only on current lactation costs and revenues.
Cow lifetime profitability should be considered to optimize culling decisions.
Lifetime monitoring of costs and revenues remains challenging for...
