AbstractFull Text

In recent years, after the emergence of the concept "race", pressure was generated in the selection process. However, in this desire to improve, it was possible to increase the production but the preservation of the global genetic diversity was affected. These changes caused great economic pressure ...

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

Retaining features of the auroch (Bos taurus primigenius), the Lidia bovine is a primitive breed originated ∼250 yr ago in the Iberian Peninsula, where is still distributed, along with France and several American countries. Selected upon a behavior, which enhances their aggressiveness; these...

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...

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

Background: The Zebu cattle are represented by a diverse group of breeds in México. Traditionally these breeds have been associated with the tough beef characteristic. Validated genetic markers have the potential to be included in marker-assisted selection and management programs in order to...

Abstract

This study was carried out in the municipality of Villaflores, Chiapas, Mexico, to determine genotypic and allelic frequencies of the leptin gene in exon 2 in dual purpose cattle. The polymorphism was observed by ARMS-PCR. 47 sires in active service in the production system were included in this...

Abstract

The objective of the present study was to estimate (co)variance components, heritabilities and genetic and phenotypic correlations for yearling weight (YW), scrotal circumference (SC) and frame score (FS) of Simmental and Simbrah young bulls from Mexico. All traits were adjusted to 365 d according...
