Abstract
The objective of this study was to assess whether the milk ELISA status for antibodies against bovine leukemia virus was associated with 305-d milk production in Canadian dairy cattle. Test results and test-day production data from 19,785 dairy cows were available for analysis. A linear mixed model was used with the estimated 305-d milk production as the outcome and lactation number, somatic cell count, calving season, days in milk, and breed as fixed effects. Herd nested in province was included as random effect. In conclusion, bovine leukemia virus antibody milk ELISA status was not associated with milk production.
