AbstractFull Text

The objective was to determine the best nonlinear and linear model to estimate the body weight (BW) of males and females of Holstein (Ho) and Brown Swiss (BS) crossed with Zebu (Z) cattle under two management systems, measuring the thoracic perimeter (TP). 1577 observations of BW and TP...

Abstract

Prolactin (PRL), growth hormone (GH), and insulin-like growth factor-1 (IGF-1) are in hormone-response pathways involved in energy metabolism during thermoregulation processes in cattle. Objective herein was to study the association between single nucleotide polymorphisms (SNP) within genes of the...

Abstract

A comprehensive life cycle assessment of the beef value chain in the United States is being conducted to provide benchmarks and identify opportunities for improvement. Region-specific data are being collected to accurately characterize cattle production practices. This study reports production...

Abstract

Methodology survival analysis model with Weibull proportional hazards was used to study Holstein cattle duration of functional productive life (FPL) in Mexico, using a model sire-maternal grandsire with Survival Kit V3.12 software. The FPL was calculated as the number of days between the date of...

Abstract

Background: National genetic evaluations for disease resistance do not exist, precluding the genetic improvement of cattle for these traits. We imputed BovineHD genotypes to whole genome sequence for 2703 Holsteins that were cases or controls for Bovine Respiratory Disease and sampled from either...

Abstract

Records of 1,289 cows at first calving with different proportions of Bos indicus and Bos taurus genes (Charolais, Brown Swiss, Simmental, Holstein Friesian, Salers) were analyzed. The cows were both purebreds and crossbreds from a commercial herd born between 1966 and 2006. They were used to...

Abstract

Production and reproduction data of cows with 50 or 75% Holstein genes kept under a dual purpose system in Yucatan, Mexico were analyzed. The work consisted of a retrospective study type using 222 lactations (n=75 cows) located at the center of Yucatán. The traits evaluated were calving interval...

Abstract

The aim of this study was to estimate genetic parameters for growth traits in Mexican Nellore cattle. A univariate animal model was used to estimate (co)variance components and genetic parameters. The traits evaluated were birth weight (BW), weaning weight (WW), and yearling weight (YW). Models...

Abstract

Heritabilities and genetic correlations between birth weight (n=13,741), adjusted 240-day weaning weight (WW, n=8,806) and age at first calving (AFC, n=3,955) of Brown Swiss cattle in Mexico were estimated. Data from 91 herds located in 19 of 32 states of Mexico from 1982 to 2006 were provided by...

Abstract

The objective of the present experiment work was to evaluate the effect of the inclusion of genomic information on the additive genetic variance of birth weight (BW) of Charolais cattle in Mexico. Variance components and heritability were estimated using four linear models. The first model was the...
