Abstract

Data from 2438 calvings born to 682 cows recorded from 2004 to 2015 in an extensive production system were used, to investigate factors associated with abortion and calf mortality until weaning. Cows belonged to Brahman, Nellore, Guzerat and Brown Swiss × Zebu breed groups. Data were analyzed using ...

AbstractFull Text

The objective was to determine the best nonlinear and linear model to estimate the body weight (BW) of males and females of Holstein (Ho) and Brown Swiss (BS) crossed with Zebu (Z) cattle under two management systems, measuring the thoracic perimeter (TP). 1577 observations of BW and TP...

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

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

The breeders of registered Swiss cattle in the central region of Chiapas, México, were characterized technically and socioeconomically through interviews and questionnaires performed in June-August, 2014, with n=30 that belonged to the Association of Pure Race Breeders in the State of Chiapas. The...

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

The aim was to assess differences among Brown Swiss (BS), Holstein (HO), BS × HO and HO × BS cows. Age (AFC) and weight at first calving (WFC) were analyzed with a simple model that included sire within breed group (SIRE) as a random effect, and breed group (BG), calving year (CY) and calving...

Abstract

The purpose of this work was to estimate the prevalence of the Translocation 1;29 (t rob 1;29) in cattle herds in the Mexican state of Zacatecas. Blood samples were obtained from 661 bovines of eight breeds: Holstein (n=284), American Swiss (n=213), Braunvieh (n=69), Simmental (n=13), Angus (n=5),...

Abstract

Heritabilities and genetic correlations between birth weight (n=13,741), adjusted 240-day weaning weight (WW, n=8,806) and age at first calving (AFC, n=3,955) of Brown Swiss cattle in Mexico were estimated. Data from 91 herds located in 19 of 32 states of Mexico from 1982 to 2006 were provided by...
