Abstract

Genetic trends are commonly used to verify genetic improvement; however, there are few reports on beef cattle in Mexico. Data from 1998 to 2013 from four Charolais bull breeding farms were examined to verify the genetic responses to different breeding management and selection criteria. Analysis...

Abstract

The objective of this study was to compare the effects of a methodology for the climatic season classification that traditionally had been used as birth season (BS) in statistical assessments. This methodology bases in an aridity index (AI) to classify BS using meteorological historic information....

AbstractFull Text

Holstein calves (n=767) from a commercial herd were used to determine the effect of birth weight (BW), weaning weight (WW) and preweaning average daily gain (ADG) on subsequent reproductive performance of heifers inseminated with sex-sorted semen in a hot environment (25°N; mean annual temperature...

Abstract

The genetic parameters for Brahman cattle under the tropical conditions of Mexico are scarce. Therefore, heritabilities, additive direct and maternal correlations, and genetic correlations for birth weight (BW) and 205 days adjusted weaning weight (WW205) were estimated in four Brahman cattle herds ...

Abstract

In order to estimate the genetic parameters and correlations between total lactation milk yield and growth traits in a multiracial population of dual purpose cattle in tropical environments of Mexico, genetic variances and covariances were estimated between total milk yield during the first (PTL1...

Abstract

An evaluation was done of productive and reproductive performance in Bos taurus (BT) × Bos indicus (BI) cattle in a dual-purpose system under tropical conditions in the state of Tabasco, Mexico. Records were from the UACH-URUSSE production unit, Teapa, Tabasco, and covered the years 1994 to 2011....

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

Records of beef cows from a ranch in southern Mexico gave 1967 birth weights (BW), 1587 weaning weights adjusted to 210 days of age (AWW) and 2001 calving intervals (CI) for the comparison of the breed groups: Brahman (BR), Guzerat (GU), Nellore (NE) and crosses born to zebu dams by Brown Swiss...

AbstractFull Text

Risk factors for stillbirth were studied in a dairy operation in northern Mexico (25°N). Data set consisted of 29406 full term calving records. Factors affecting stillbirths were analyzed using a step-wise multivariable logistic regression models. The predictive indicators of stillbirth risk were:...

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...
