| During the last decade, microsatellites (short tandem repeats or STRs) have been successfully used for animal genetic identification, traceability and paternity, although in recent year single nucleotide polymorphisms (SNPs) have been increasingly used for this purpose. An efficient SNP identification system requires a marker set with enough power to identify individuals and their parents. Genetic diagnostics generally include the analysis of related animals. In this work, the degree of information provided by SNPs for a consanguineous herd of cattle was compared with that provided by STRs. Thirty-six closely related Angus cattle were genotyped for 18 STRs and 116 SNPs. Cumulative SNPs exclusion power values (Q) for paternity and sample matching... |

| The influence of cytoplasmic inheritance on birth and weaning weight was evaluated in an experimental Hereford herd. Data on 1,720 records for birth and weaning weights from calves born between 1963 and 2002 were studied. Variance components were estimated using MTDFREML procedures and an animal model was fitted for each trait. Direct and maternal additive effects and permanent environment and maternal lineage effects were treated as random, while year and month of birth, age of dam and sex of the calf were treated as fixed. Identification of maternal lineages was based on pedigree information. The contribution to phenotypic variance of cytoplasmic lineages defined by pedigree information was negligible for both traits. Mitochondrial genotypes of cows... |

| Se evaluó la presencia del virus de la leucosis bovina (VLB) en 360 muestras de ADN de ocho razas bovinas criollas: Blanco Orejinegro (BON), Casanareño (CAS), Costeño con Cuernos (CCC), Chino Santandereano (ChS), Caqueteño (CQT), Hartón del Valle (HV), Romosinuano (RS) y San Martinero (SM), dos Razas Sintéticas Colombianas: Lucerna (LUC) y Velásquez (VEL) y dos razas foráneas: Brahmán (B) y Holstein (H). Para la detección del pro-virus se amplificó una región del gen env viral, mediante PCR anidada. La presencia del VLB fue mayor en la raza HV seguido por ChS (83.3% y 60% respectivamente), VEL y LUC tuvieron el mismo porcentaje (50%), en CAS, CCC y CQT la presencia del virus fue de 26.7%, 23.3% y 16.7% respectivamente; no se encontró el virus en BON, SM y... |
