Rabbits can live upto between 10-12 years. Longest rabbit to have lived clocked 18yrs in the Guinness book of records. Life span entirely dependents on how well you take care of the rabbits and the purposes for breeding them. On selection and breeding,yes you can select the best males as replacement stock but remember to have clear records and identifications so as not to fall a victim of inbreedingInformative,,,, what is the lifespan of rabbits,,,, should i change the male rabbit which have sired once and keep the young ones for future mating????
