The levels of artificial insemination and missing sire information make genomic selection not always beneficial in meat sheep

چکیده
Numerous meat sheep breeding programs in developed and developing countries are characterized by incomplete sire information a predominant use of natural matings. These two parameters potentially affect the benefit genomic selection (GS), especially for late-in-life trait. Using stochastic simulations, genetic gains obtained using conventional strategies maternal trait were evaluated population. Natural mating artificial insemination (AI)-based designs, inspired current diversity designs used French breeds, modeled three tested compared with strategy: parentage assignment, GS based on male or female reference Genomic population did not always outperform selection. Its depended design, level missing dam sires, AI. outperformed strategy, even if only 25 % females nucleus genotyped.
