Pedigree analysis in the Brazilian Zebu breeds.
Zebu breeds play an important role in cattle production systems in Brazil. To assess the genetic variability from animals in the Herd Books of Nelore, Gir and Guzerat breeds, generation intervals, inbreeding, effective population size and parameters of gene origin (effective number of founders, ancestors and founder genomes) were calculated using pedigree records from 1938 to 1998. Breed subdiv...
متن کاملOrigins and genetic diversity of British cattle breeds in Brazil assessed by pedigree analyses.
Pedigree information available for Angus (ANG), Devon (DEV), Hereford (HER), and Shorthorn (SHO) cattle in Brazil was analyzed to appraise the genetic diversity and population structure of these breeds. Pedigree records collected from the beginning of the 20th century until 2010 were used in the analyses. Over time, the number of herdbook registrations declined in HER after a peak in the 1970s,...
متن کاملGenetic variability and population structure of Raeini Cashmere goat breed assessed from pedigree analysis
Pedigree information which collected from 1979 to 2012 were used to study the genetic variability and population structure of Raeini Cashmere goat, taking kids born from 2009 to 2012 into account as reference population. Averages of inbreeding coefficients in whole and inbred populations were computed to be 0.04% and 4.41%, respectively. Considering the reference population, average inbreeding ...

متن کاملGenetic Diversity among European Cattle Breeds
Over the centuries since mankind first started farming, genetic variation has allowed the selection of the improved crops and livestock that have fed an ever increasing population. Maintaining genetic variation is crucial if we want to continue to improve our livestock and respond to changes in climate, disease or consumer preferences. This article describes work at the Roslin Institute on the ...
