Influence of temperament-related genes on live weight traits of Charolais cows R. Bras. Zootec.
Garza-Brenner,Estela; Sifuentes-Rincón,Ana María; Rodríguez-Almeida,Felipe Alonso; Randel,Ronald D.; Parra-Bracamonte,Gaspar Manuel; Arellano-Vera,Williams.
Abstract We investigated whether a panel of molecular markers previously associated with temperament has an effect on live growth traits. Phenotypic data from 412 Charolais cows categorized according to their age in adult and young cows were used to determine Pearson's correlations between birth (BW), weaning (WW), and yearling live (YW) weight and temperament traits (measured as exit velocity [EV] and temperament score [TS]). For association analysis, selective genotyping of a group of 80 cows identified as the most docile and temperamental were genotyped with a 151-SNP (single-nucleotide polymorphisms) panel of molecular markers previously associated with temperament. Significant Pearson's correlations between birth weight and weaning weight and the two...
