Abstract

Data are typically discarded when there are inconsistencies in a database, or when information is discrepant or out of range for the biological characteristics of the species being analyzed. However, such loss of information could have considerable implications for genetic evaluation of cattle....

Abstract

Weaning weight (W205) data from 12 181 Tabapuã cattle, raised under pasture regime in the Northeast region of Brazil, were studied using one-trait analysis under five different models for animals, containing random direct genetic effect from the animal, including or not maternal genetic and...

Abstract

The objective was to compare models by Bayes factor (BF) to estimate the (co)variance components, genetic parameters and genetic values for the adjusted weights at 205 (W205), 365 (W365) and 550 (W550) days of age in Tabapuã animals reared on pasture in the Brazilian Northeast. Information about...

AbstractFull Text

Direct diagnoses were made by using - blood smears and nested PCR (nPCR) tests on 309 blood samples from crossbred dairy cattle in the municipality of Ibicaraí, Bahia. From diagnostic blood smear slides, the observed parasitic frequencies were 31.1% for Anaplasma marginale and 20.4% for Babesia sp. ...

AbstractFull Text

The objective in this study was the analysis of nonlinear models to describe growth of Nellore cattle raised in Bahia State. Data from 6,855 animals weighed at 90-day intervals from birth up to two years of age were used, based on records from the Brazilian Association of Zebu Breeders (ABCZ). The...

AbstractFull Text

The aim of this study was to estimate the effective size and generation interval in Tabapuã state of Bahia. Pedigree data were used to breed animals Tabapuã provided by the Brazilian Association of Zebu Breeders (ABCZ). The data file consisted of 30,202 observations between the years 1964 to 2006....

AbstractFull Text

The objective, in this study, was to estimate the genetic parameters and to evaluate both genetic and phenotypic trends for the weight at 205 (W205) and 365 (W365) days of age in Indubrazil cattle, born between 1976 and 2006, raised in Sergipe. The variance components and genetic values were...

Abstract

The objective of this study was to evaluate the Pure Nelore cattle breed background in the Brazilian Northeastern Sertão region by determining its population structure and quantifying genetic, phenotypic and environmental progress based on ponderal development traits. Pedigree data of animals born...

Abstract

The objective of this work was to evaluate the population structure and the genetic and phenotypic progress of Nelore cattle in Northern Brazil. Pedigree information concerning animals born between 1942 and 2006 were analyzed. Population structure was performed using the Endog program. Out of the...
