Abstract
Koeck, A., Miglior, F., Kelton, D. F. and Schenkel, F. S. 2012. Short Communication: Genetic association of body condition score with disease resistance in first lactation Canadian Holsteins. Can. J. Anim. Sci. 92: 285–289. The objective of this study was to investigate if body condition score (BCS) can be used as an indicator of specific diseases in first lactation Canadian Holstein cows. Body condition score was routinely recorded by professional type classifiers, as part of the national type classification system. Health data recorded by producers were available from the national dairy cattle health recording system. Body condition score was genetically negatively correlated with several health disorders, indicating that animals with a higher BCS have fewer disease cases. The results imply that BCS could be used to indirectly select for animals that are more resistant to specific diseases.
