Abstract excerpt
Hyperketonemia is a common metabolic disorder in early-lactation dairy cows that impairs milk performance and health. The gold-standard indicator for diagnosis is the blood metabolite BHB. However, measuring blood BHB on a large scale is cumbersome and expensive, resulting in a paucity of available phenotypes, therefore precluding hyperketonemia from most genetic evaluation systems. An alternative approach is the...
