摘要：
The objective of this study was to investigate if milk beta-hydroxybutyrate (BHBA) can be used as an indicator of ketosis. The different measures of milk BHBA were moderately genetically correlated with ketosis. The results imply that milk BHBA could be used to indirectly select animals that are more resistant to ketosis.
