Evaluation of inbreeding in laying hens by applying optimum genetic contribution and gene flow theory.

Abstract

Due to consistent increases of inbreeding of on average 0.95% per generation in layer populations, selection tools should consider both genetic gain and genetic relationships in the long term. The optimum genetic contribution theory using official estimated breeding values for egg production was applied for 3 different lines of a layer breeding program to… (More)
