Abstract

The objective of this study was to evaluate genetic diversity of seven Mexican beef cattle populations, using pedigree analyses. The analyses were carried out with the Endog software, using information of the registered animals on national herd-book of each breed. The size of the populations...

Abstract

High salt concentration in drinking water on dairy cattle farms in the semiarid region of northern Mexico is a concern because it can negatively affect health and productive performance of dairy cows. The study was conducted to assess the effect of drinking water quality on feed intake, daily milk...

Abstract

The objective of this study was to determine the magnitude of genotype by climate interaction (GCI) in the national genetic evaluation for weaning (WW) and yearling (YW) weights of Mexican Braunvieh cattle. The numbers of performance records and animals in the pedigree were 12,364 and 25,173 for...

Abstract

In México, there are no studies whose purpose has been characterizing the production units with registered cattle herds. These studies are important because they allow designing successful genetic improvement programs and the transfer of their results to commercial producers. The objective of this...

Abstract

The objective of the present study was to determine the best possible percentage of Bos taunts (BT) genes on age-at-first-calving (AFC), days to first post-partum service (DFPS), days open (DO) and calving interval (CI) in crossbred cows. Data was collected in a typical commercial dairy farm of...

Abstract

The purpose of this study was to evaluate the stability of results from genetic evaluations for growth traits in Mexican populations of Tropicarne and Braunvieh cattle. The analysed information came from the genetic evaluations for Tropicarne cattle in 2002 and 2003 and for Braunvieh in 2003 and...

Abstract

The inclusion of the inbreeding coefficient (F) into the models to predict breeding values (BV) for Jersey (J) and Brown Swiss (BS) Mexican registered dairy cattle was studied. The conventional model including the fixed effect of herd-year-season, and the genetic additive and permanent...

Abstract

The objective was to evaluate the effect of cow's body weight at first-mating on the productive and reproductive performance in Tropicarne cows. Body weight categories were based on cow's predicted breeding value for weight at first breeding adjusted by age within contemporary group (year-breeding...

Abstract

The study was conducted to determine the six alternatives of contemporary group (CG) definition for the genetic evaluation of weaning weight of Braunvieh cattle in Mexico. The performance data of calves born between 1995 and 2002 in 33 herds in 12 states of Mexico were used in the data. Different...
