Effects of polymorphic microsatellites in the regulatory region of IGF1 and GHR on growth and carcass traits in beef cattle
(Blackwell Publishing, 2005-02-01)
Growth hormone (GH), insulin-like growth factors 1 and 2 (IGF1 and IGF2) and their associated binding proteins and transmembrane receptors (GHR, IGF1R and IGF2R) play an important role in the physiology of mammalian growth. ...

Genetic parameters for pre-weaning traits in Braunvieh cattle
(FUNPEC-EDITORA, 2009)
The objective of this study was to estimate genetic parameters for pre-weaning traits of Braunvieh cattle raised under tropical conditions in Brazil. The weight and weight gain parameters were birth weight (BW, N = 9955), ...
Estimates of genetic parameters for carcass, growth and reproductive traits in Nellore cattle
(2013-07-01)
The objective of this study was to estimate genetic parameters for female mature weight (FMW), age at first calving (AFC), weight gain from birth to 120 days (WG_B_120), from 210 to 365 days (WG_210_365), rib eye area ...
Comparison of methods for predicting genomic breeding values for growth traits in Nellore cattle
(2021-07-01)
The objective of this study was to evaluate the accuracy of genomic predictions of growth traits in Nellore cattle. Data from 5064 animals belonging to farms that participate in the Conexão DeltaGen and PAINT breeding ...

Genetic and environmental heterogeneity of residual variance of weight traits in Nellore beef cattle
(Biomed Central Ltd., 2012-06-06)
Background: Many studies have provided evidence of the existence of genetic heterogeneity of environmental variance, suggesting that it could be exploited to improve robustness and uniformity of livestock by selection. ...
