Abstract

Charolais cattle are one of the most important breeds for meat production worldwide; in México, its selection is mainly made by live weight traits. One strategy for mapping important genomic regions that might influence productive traits is the identification of signatures of selection. This type...

Abstract

Tenderness and marbling are polygenic traits used as indicators of good meat quality. Among different genes related to meat quality, µ-calpaine (CAPN1) and thyroglobulin (TG5) have been specifically linked to tenderness and marbling, respectively. Objectives: To estimate the allelic and genotypic...

Abstract

Background: The search for gene and marker effects on economically important traits is aimed not only to understanding the genetic architecture of complex traits but also to applying the information to breeding schemes. Objective: To analyze the effect of two temperament-related SNPs (rs109576799...

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....

Abstract

The Q204X myostatin allele was identified by an allelic discrimination assay using DNA from 34 Charbray bulls under performance testing in northwest Mexico. A total of 9.3% of the bulls were heterozygotic Q204X allele carriers and gene frequency was 5%. This is the first report of the Q204X allele...

Abstract

Samples from registered Charolais sire candidate bulls for breeding herds and managed in a performance test station (n=130) in Mexico were analysed in order to estimate genotypic and allelic frequencies of three single nucleotide polymorphisms associated to beef quality traits. Two Calpain gene SNP ...

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

Dairy cattle shows their genetic potential in different efficiency levels depending on the region in which they live; this effect is referred to as interaction genotype × environment (IGE) and may have implications for the genetic improvement of dairy cattle in Mexico. This phenomenon should be...

Abstract

Polymorphisms in candidate genes can produce significant and favorable changes in the phenotype, and therefore are useful for the identification of the best combination of favorable variants for marker-assisted selection. In the present study, an assessment to evaluate the effect of 11 single...

Abstract

Heritable abnormalities can cause a reduction in productive performance, structural defects, or death of the animal. There are reports of hereditary abnormalities in Braunvieh cattle from several countries, but no evidence was found on their existence in Mexico. In this study, 28 genes associated...
