Extract

Livestock selection programmes have progressed from visual assessments to the use of quantitative information from multiple sources. More recently genetic markers have been used to incorporate information from quantitative trait loci (QTL) into selection decisions. The uptake this technology has been slow due to the cost and difficulty of discovering and using QTL. For a number of livestock species single nucleotide polymorphism (SNP)-chips are becoming available. These have the ability to genotype 10,000s of SNP markers in a single assay. This opens up the possibility of ‘genome wide selection’ (GWS) to ‘tag’ most of the genetic variants contributing to trait differences. This paper discusses what impact GWS might have in the main NZ livestock breeding industries (dairy, beef, sheep and deer).
