The GH hormone and Pit-1 factor have been shown to be involved in the physiological mechanisms related to growth. The present study was carried out to investigate the possible association of the polymorphism at GH1 and POU1F1 loci with meat production traits in Piemontese cattle. Fourteen traits were considered, expressing growth (weight at 5, 7 and 11 months, daily gain), size (withers height, trunk length, chest girth at 12 months) and meat conformation (withers width, shoulder muscularity, loins width, loins thickness, thigh muscularity, thigh profile, bone thinness). Data were analyzed with a mixed model procedure to estimate the allele substitution and the dominance effects. The results did not provide evidence of association of GH1 and POU1F1 polymorphisms with the evaluated traits.

Abstract
The GH hormone and Pit-1 factor have been shown to be involved in the physiological mechanisms related to growth. The present study was carried out to investigate the possible association of the polymorphism at GH1 and POU1F1 loci with meat production traits in Piemontese cattle. Fourteen traits were considered, expressing growth (weight at 5, 7 and 11 months, daily gain), size (withers height, trunk length, chest girth at 12 months) and meat conformation (withers width, shoulder muscularity, loins width, loins thickness, thigh muscularity, thigh profile, bone thinness). Data were analyzed with a mixed model procedure to estimate the allele substitution and the dominance effects. The results did not provide evidence of association of GH1 and POU1F1 polymorphisms with the evaluated traits.
