Abstract Background Bovine renal lipofuscinosis BRL is an incidental finding in cattle at slaughter. Condemnation of the kidneys as unfit for human consumption was until recently considered the only implication of BRL. Recent studies have indicated a negative influence on the health of affected animals. The present study investigated the prevalence genetics and effect of BRL on milk yield and weight at slaughter. Methods BRL status of slaughter cattle was recorded at four abattoirs during a 2-year-period. Data regarding breed age genetic descent milk yield and
