Abstract

This report describes an unusual case of dystocia caused by the presence of ischiopagus conjoined twin calves in a primiparous Holstein Friesian cow, which was successfully resolved through a partial fetotomy and a caesarean section, in a Mexican dairy farm.

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

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

Copy number variants (CNVs) are an important source of genomic structural variation, recognized to influence phenotypic variation in many species. Many studies have focused on identifying CNVs within and between human and livestock populations alike, but only few have explored population-genetic...

Abstract

Genealogical information is an essential tool for carrying out any genetic improvement program. The objective of this study was to determine the accuracy of pedigree information in the Mexican registered Holstein population using genomic data available in Mexico and for the US Holstein population....

Abstract

In pasture-based dairy systems, there is a close relationship between milk production and dry matter intake (DMI), hence the importance of measuring these variables, although obtaining this information implies high labour and costs. The objective of this study was to design a mathematical model to...

Abstract

Variance components and genetic parameters were estimated for total milk production at first lactation (MP1), milk yield adjusted to 305 d and adult equivalent at the first lactation (MP1std), total milk production of the first five lactations (MP5) and milk yield adjusted to 305 d and mature...

Abstract

The association of single nucleotide polymorphisms (SNPs) within genes of the prolactin (PRL), growth hormone (GH) and insulin-like growth factor-I (IGF1) pathways with 305-day milk yield (MY305) were evaluated in heat-stressed Holstein cows. Ambient temperature and relative humidity were used to...
