Growth rate and carcass quality in pigs as related to genotype at loci POU1F1/RsaI (Pit1/RsaI) and GHRH/AluI*

چکیده
The aim of the study was to determine the effect of pituitary transcription factor 1 (POU1F1, Pit1) and the polymorphism of growth hormone releasing hormone (GHRH) genes on selected pig performance traits. The animals used were the progeny of Polish Landrace × Polish Large White crossbred sows and Polish Landrace, Polish Large White, Duroc or Pietrain boars. Eighteen perfor-mance traits were recorded. The POU1F1 genotype was found to have a significant effect on mean daily live weight gain (g), ham-covering fat (kg), fat thickness over loin (cm), meat content of carcass (%) and meat content of ham (%), while the GHRH/AluI genotype was significantly associated with fat thickness over shoulder (cm) and meat content of carcass (%). The results presented show that the region of chromosome 13, covering the POU1F1-encoding gene, may contain quantitative traits loci (QTLs) for growth rate and carcass traits. The study supplied new information on the relation between the polymorphism of GHRH-encoding gene and pig performance.

Analysis of associations of PIT1 genotypes with growth, meat quality and carcass composition traits in pigs.
PIT1 was chosen as a candidate gene to investigate its associations with growth, meat quality and carcass composition traits in the pig. PIT1 is known as the pituitary-specific activator of the growth hormone in several mammals. Furthermore, PIT1 is a positive regulatory factor of prolactin and thyroid-stimulating hormone beta. PIT1 is a member of the POU-domain family of genes and is located o...

Abstract One of the latest methods which can improve the accuracy of prediction and response to selection is the selection based on markers. Research has shown that the POU1F1 (Pit-1) gene has important role in the regulation of animal growth and associated with carcass, weight and milk traits. The purpose of this research was to study polymorphisms of POU1F1 gene and their association with...
