AbstractFull Text

The objective of this study was to evaluate genotype × environment interaction (G × E) between Canada, the United States and Mexico for fertility and milk yield traits using genetic correlations between countries estimated from genetic evaluations of sires. Genetic correlation between Mexican and...

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

Polynomial regression models of the first, second, and third order were used to fit milk production deviations of daughters in Mexico on Canadian and US predicted transmitting ability values for 305-d mature-equivalent milk production (kg). For the pairs Canada-Mexico and Mexico-United States, 40...

Abstract

The objective of this study was to evaluate the influence of breed, breed and sex of the calf, farm, calving number (CN), type of calving, and their interactions on CI using records from four different beef breeds performing in the humid tropical environment of Mexico. The influence of these...

Abstract

Carmen mountain white-tailed (Odocoileus virginianus carminis) is one of the 14 white-tailed deer subspecies distributed in Mexico. In the northeastern region, the beef cattle-deer model has been described as a highly successful system of wildlife conservation. In this area, there are three...

AbstractFull Text

The aim of this study was to estimate phenotypic and genetic (co)variances for reproductive and lactation curve characteristic in Holstein cattle using multivariate animal models within the first three parities from 766 cows and 126 sires in a herd in Northern Mexico. Individual lactations were...

AbstractFull Text

The aim of this study was to estimate crossbreeding effects for milk production and reproductive traits in a multibreed population result of crosses of Holstein, Simmental and Swiss Brown × Zebu, using univariate animal models from 697 to 4923 calving records in six experimental herds in humid...

AbstractFull Text

Genetic (co)variances were obtained for milk production and reproductive traits in a multibreed population result of crosses of Holstein, Simmental and Swiss Brown × Zebu, from 696 to 4923 records obtained in six experimental herds in Mexico from 1969 to 2004. Heritability for 305-d milk production ...

Abstract

The aim of this study was to estimate genetic and phenotypic (co)variances for lactation curve traits and for days open in Holstein cows. Data included 1 579 lactations from 766 cows, daughters of 126 sires in a dairy herd in northern Mexico. The studied traits within lactation were days open (DO), ...

AbstractFull Text

Genetic parameters for milk (MP) and protein (PP) productions corrected to mature equivalent and 305 days of milking, adjusted somatic cell counts (SCC), first to second calving interval (CI) and age at first calving (AC) were estimated on Mexican Holstein cows. A set of univariate sire models was...
