The aim of this work was to study the association between five single-nucleotide polymorphisms (SNPs), each in one of five genes (CTSL, EPOR, ESR2, GPX5, and STAT5B), and functional teat number (FTNUM). Each marker was genotyped in at least 940 Italian Large White sows. All SNPs segregated in the analyzed breed with minor allele frequencies ranging from 0.18 (CTSL and EPOR) to 0.40 (ESR2). The genotyped sows were categorized into two classes based on their FTNUM: FTNUM equal to 14 (59% of the samples) and FTNUM greater than 14 (41%). Differences in allele frequencies between the two classes were statistically significant (P < 0.01) for the GPX5 polymorphism.

Abstract
The aim of this work was to study the association between five single-nucleotide polymorphisms (SNPs), each in one of five genes (CTSL, EPOR, ESR2, GPX5, and STAT5B), and functional teat number (FTNUM). Each marker was genotyped in at least 940 Italian Large White sows. All SNPs segregated in the analyzed breed with minor allele frequencies ranging from 0.18 (CTSL and EPOR) to 0.40 (ESR2). The genotyped sows were categorized into two classes based on their FTNUM: FTNUM equal to 14 (59% of the samples) and FTNUM greater than 14 (41%). Differences in allele frequencies between the two classes were statistically significant (P < 0.01) for the GPX5 polymorphism.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
