Associations between single nucleotide polymorphisms and carcass traits in Nellore cattle using high-density panels.
The objective of this study was to evaluate associations between single nucleotide polymorphism (SNP) markers and carcass traits measured postmortem in Nellore cattle. Records of loin eye area (LEA) and backfat thickness (BF) from 740 males and records of hot carcass weight (HCW) from 726 males were analyzed. All of the animals were genotyped using the BovineHD BeadChip. Association analyses we...
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 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 کاملPolymorphisms in TOX and NCOA 2 genes and their associations with reproductive traits in Nellore cattle
In cattle, phenotypic expression of reproductive traits occurs late in life. The identification of causal mutations in genes affecting reproduction permits the inclusion of these SNPs in customized DNA chips to increase accuracy. Therefore, the aim of this study was to detect causal mutations in the TOX and NCOA2 genes previously identified by genome-wide association studies of zebu cattle. DNA...
متن کاملGenetic correlations between mature cow weight and productive and reproductive traits in Nellore cattle.
We investigated genetic associations between mature cow weight (MW) and weaning weight (WW), yearling weight (YW), weight gain from birth to weaning (GBW), weight gain from weaning to yearling (GWY), weaning hip height (WHH), yearling hip height (YHH), scrotal circumference (SC), and age at first calving (AFC). Data from 127,104 Nellore animals born between 1993 and 2006, belonging to Agr...
