the aims of the present study were to propose apolymerase chain reaction-restriction fragment length polymorphismpcr-rflp genotyping method for the ay_376689:c.773c>t single nucleotide polymorphism snp of the equine prkag3 gene, related to muscle performance, as well as to characterize this snp and a second polymorphism, aawr_02017454:g.121684t>c of the spata1 gene, related to male fertility, i...

5'-AMP-activated protein kinase (AMPK) activity is increased during exercise in an intensity- and glycogen-dependent manner. We previously reported that a mutation in the AMPK3 subunit (Prkag3225Q) increases AMPK activity and skeletal muscle glycogen content. Transfection experiments revealed the R225Q mutation is associated with high basal AMPK activity and diminished AMP dependence. Thus, the...

The objective of this study was to determine the association of single nucleotide polymorphisms (SNP) in selected candidate genes with sensory and technological meat quality traits in commercial cattle. SNP in seven candidate genes were genotyped in 130 crossbred Bos taurus cattle using PCR-RFLP. Reported associations between calpastatin (CAST) and Warner-Bratzler shear force and carboxypeptida...

Introduction Meat quality describes properties and perceptions of meat. For industry, cooking yield is also economically relevant. Many challenges face the meat industry and there is a need to identify genetically superior animals for these traits (Mullen et al., 2006). Tenderness, intramuscular fat (IMF) level and waterholding capacity are beef quality traits with moderate heritability, but wh...

Numerous reports have described genetic markers or genomic regions (QTL) associated with pork quality and/or palatability but few validation studies have been reported. Therefore, 156 SNP markers from 45 candidate genes and eight QTL regions were analyzed for association with pork quality and palatability traits from 888 pork loins. Loins were collected at three slaughter facilities and selecte...
