Optimizing Genetic management within Populations with a Simulation Tool

Abstract Text: The optimal contribution method is available to control relatedness within populations, but less suitable for less controlled breeds. The effectiveness of simpler methods is often unclear. With a newly developed computer simulation program the effectiveness of methods can be determined for any kind of population. For a pig breed, using an AI-boar on the small Dutch population was simulated. Use of a German boar could help to decrease inbreeding rates. The most effective sire restriction was investigated in a dog population. Surprisingly, restricting matings  per life was less effective than per year. Overall managing population kinship was most effective to reduce inbreeding rates. Simulation can be effective in demonstrating principles and can be used as an educational tool. Genetic management needs to be tailored for specific populations  taking both the technical effectiveness and its applicability into account.
