Microarray of SNPs for diverse applications in commercial pig breeding.

Modern pig production needs new tools for fast, reliable, more effective breeding. In the present paper we present a chip containing 45 SNP (Single Nucleotide Polymorphisms) which enables the determining of 1 genetic disease (PSS-Porcine Stress Syndrome), 4 QTLs genes: PRKAG3, CAST, MC4R and ESR, which together with the remaining SNPs create a panel useful in marker-assisted selection and veterinary control. The SNPs were genotyped using the PCR-APEX (Arrayed Primer Extension) technique.
