Associations between polymorphism of some candidate genes and growth rates, feed intake and utilisation, slaughter indicators and meet quality in cattle (original) (raw)

2005, Archiv für Tierzucht

We showed that the leucine/valine substitution at amino acid position 127 of the bovine growth hormone (GH) affects growth rate, feed intake/feed conversion as well as carcass traits in dairy and beef cattle. This indicates the GH gene as a potential locus of quantitative traits (QTL) in cattle. Moreover, associations were studied between the polymorphism at GH receptor (GHR), leptin (LEP), STAT5A, and PIT-1 loci and traits related to meat production in the growing Polish Friesian and beef bulls. Statistically significant ...
