It reduces the fertility and also the productivity of an animal.Continuous inbreeding among cattle causes inbreeding depression.It decreases the fertility and, even, productivity of an animal.It can be overcome by applying outbreeding, in which mating is done between different breeds or individuals of the same breed but having no common ancestors.Outb reeding includes out-crossing, cross-breeding and interspecific hybridisation.
