Estimation of genomic breeding values for milk yield in UK dairy goats
Recent availability of the Illumina caprine 50K chip (Illumina Inc., San Diego, CA; Tosser-Klopp et al. 2012) allows for the implementation of genomic selection in dairy goats. However due to the smaller scale of the goat breeding industry compared to cattle or poultry it is important to select an optimal method that can accommodate the structure (mixture of dams and sires), and small size of the reference population. Females are usually not included in the reference population in dairy cattle as there are thousands of bulls with accurate proofs. However, smaller populations have to supplement the reference population with females to increase prediction accuracy. The objective of this study was to evaluate two different methods for the estimation of genomic breeding values in dairy goats with a small reference population.
