"In this study, we determined culling and mortality in adult breeding rabbits on 130 commercial farms in Spain during 2000-2005. The median size of the farms was 595 does (minimum to maximum: 131-5500 does)," scientists in Madrid, Spain report. "The median culling age per doe was 14.9 months old and 6 kindlings. The median monthly removal risk (MMR) in does was 9.3%, with 3.4% dead and 5.7% culled (including euthanized does). The MMR was negatively correlated with the degree of intensification of the reproductive rhythm (r=-0.37), age at first mating (r=-0.31) and kindling interval (r=-0.36). The MMR in males was 5.8% (1.2% dead and 4.2% culled or euthanized). Our...
