Genomics in small populations: the MRY breed

Year: 2017

Type: article

Abstract: A feasibility study for a genomic evaluation for the Meuse-Rhine-Yssel (MRY) Red and White dual purpose breed was conducted.Aim was to improve genetic progress in this small population.For this, 550 MRY bulls were genotyped from the German and Dutch-Flemish populations.Added reliability of genomic evaluation was assessed in a validation study using approximately (trait dependent) 400 bulls as training population and another 100 as validation bulls.Mean gain in reliability over parent average was 8.4 percent (7.4 EDC).For production traits added reliability was on average 15.9 percent (1.2 EDC).For conformation added reliability averaged 9.6 percent (2.3 EDC).For functional traits, added reliability tended to be low.As a result of this study, a genomic evaluation for the MRY breed will be implemented in the breeding program.Another 2,000 cows are currently being genotyped to improve evaluation accuracies.
