Genetic association of growth traits with carcass and meat traits in Nellore cattle.
The aim of this study was to estimate genetic and phenotypic associations of growth traits with carcass and meat traits in Nellore cattle. Data from male and female animals were used for weaning weight (WW; N = 241,416), yearling weight (YW, N = 126,596), weight gain from weaning to yearling (GWY, N = 78,687), and yearling hip height (YHH, N = 90,720), respectively; 877 male animals were used f...
متن کاملFrequencies of candidate genes and associations with carcass and meat traits in Nellore and crossbred cattle
The objective of this work was to estimate allelic frequencies of the polymorphisms IGF2/MboII (G > T) of the insulin‐like growth factor 2 (IGF2) gene, DQ499531.1:g.134A > T of the pro‐melanin‐concentrating hormone (PMCH) gene, and DQ667048.1:g.3290G > T of the RAR‐related orphan receptor C (RORC) gene in beef cattle of different genetic groups, and to evaluate the associations between these po...
متن کاملPhenotypic and Genetic Correlations of Feed Efficiency Traits with Growth and Carcass Traits in Nellore Cattle Selected for Postweaning Weight
This study evaluated phenotypic (rph) and genetic correlations (rg) between 8 feed efficiency traits and other traits of economic interest including weight at selection (WS), loin-eye area (LEA), backfat thickness (BF), and rump fat thickness (RF) in Nellore cattle. Feed efficiency traits were gain:feed, residual feed intake (RFI), residual feed intake adjusted for backfat thickness (RFIb) and ...
متن کاملGenetic relationship between growth and reproductive traits in Nellore cattle.
The objective of this study was to evaluate the genetic relationship between postweaning weight gain (PWG), heifer pregnancy (HP), scrotal circumference (SC) at 18 months of age, stayability at 6 years of age (STAY) and finishing visual score at 18 months of age (PREC), and to determine the potential of these traits as selection criteria for the genetic improvement of growth and reproduction in...
متن کاملAssociation of single nucleotide polymorphisms with carcass traits in Nellore cattle.
The association between two single nucleotide polymorphisms (SNPs), T945M and UCP1SNP1, with hot carcass weight (HCW, kg, N = 618), longissimus dorsi muscle area (REA, cm(2), N = 633), and backfat thickness (BF, mm, N = 625), measured in Nellore cattle in Brazil, was evaluated. Likelihood ratio tests were used to evaluate reduced (fixed effects of general mean, contemporary group, yearling weig...
