Genetic parameters and trends for traits of the Hereford and Braford breeds in Brazil
Livestock Science, 2018Abstract The objective of this study was to estimate genetic parameters and genetic trends of Hereford and Braford breeds for growth traits and visual scores. Data consisting of records for 205-day weight (W205), 550-day weight (W550), 345-day post weaning gain (PWG345), scrotal circumference at 550 days (SC), and muscling (MUS) and frame (FRA ...

The aim of this study was to assess the seasonal effects of the environment on semen quality in bulls, using infrared thermography. Sperm motility (M), mass motion (MM), and vigor (VIG) were evaluated in sperm samples from 17 Bradford bulls aged approximately 24 months at the beginning of the study.

Genomic Wide-Selection for Tick Resistance in Hereford and Braford Cattle via Reaction Norm Models
2014The objective of this study was to compare a conventional genomic model (GBLUP) and its extension to a linear reaction norm model (GLRNM) specifying genotype by environment interaction (G*E) for tick resistance in Brazilian cattle. Tick counts (TC) from 4,363 Hereford and Braford cattle from 146 contemporary groups (CG) were available of which 3,591 ...
