Pedigree analyses in the breeding program for nellore cattle. Author(s): VOZZI, P. A.; MARCONDES, C. R.; BEZERRA, L. A. F.; LÔBO, R. B. Parameters based on the probability of gene origin were used to describe genetic variability in three reproductive groups from the Breeding Program for Nellore Cattle (PMGRN). The three reproductive p... ... Repository: BDPA Publication year: 2007

A genome-wide scan for selection signatures in Nellore cattle. Author(s): SOMAVILLA, A. L.; SONSTEGARD, T. S.; HIGA, R. H.; ROSA, A. do N.; SIQUEIRA, F.; SILVA, L. O. C. da; TORRES JUNIOR, R. A. de A.; COUTINHO, L. L.; MUDADU, M. de A.; ALENCAR, M. M. de; REGITANO, L. C. de A. Brazilian Nellore cattle (Bos indicus) have been selected for growth traits for over more than four decades. In recent years, reproductive and meat quality traits have become more important because of... ... Repository: BDPA Publication year: 2014
Implementation of DNA markers to produce genomically enhanced EPDs in Nellore cattle. Author(s): LÔBO, R. B.; NKRUMAH, D.; GROSSI, D. do A.; BARROS, P. S. de; PAIVA, P.; BEZERRA, L. A. F.; OLIVEIRA, H. N. de; SILVA, M. V. G. B. Background: The sequencing and publication of the cattle genome and the identification of single nucleotide polymorphism (SNP) molecular markers have provided new tools for animal genetic evaluation a... ... Repository: BDPA Publication year: 2011
Genotypic and allelic frequencies of gene polymorphisms associated with meat tenderness in Nellore beef cattle. Author(s): CARVALHO, M. E.; ELER, J. P.; BONIN, M. N.; REZENDE, F. M.; BIASE, F. H.; MEIRELLES, F. V.; REGITANO, L. C. de A.; COUTINHO, L. L.; BALIEIRO, J. C. C.; FERRAZ, J. B. S. The objectives of this study were to characterize the allelic and genotypic frequencies of polymorphisms in the μ-calpain and calpastatin genes, and to assess their association with meat tenderne... ...

The reproductive performance of bulls has a high impact on the beef cattle industry. Scrotal circumference (SC) is the most recorded reproductive trait in beef herds, and is used as a major selection... ... Repository: BDPA Publication year: 2014
Essential oils in nellore beef cattle: in vivo impact on rumen emissions. Author(s): BENETEL, G.; FAGUNDES, G. M.; MÉO FILHO, P. de; SILVA, T. dos S.; WELTER, K. C.; MELO, F. A.; LOBO, A. A. G.; FRIGHETTO, R. T. S.; BERNDT, A.; MUIR, J. P.; BUENO, I. C. da S. Abstract: Essential oils (EOs), as rumen additives, decreased CH4 emissions in in vitro trials but results from in vivo studies are still limited. We investigated the effects of Origanum vulgare (OEO)... ... Repository: BDPA Publication year: 2024
Relationship between residual feed intake and enteric methane emission in Nellore cattle. Author(s): MERCADANTE, M. E. Z.; CALIMAN, A. P. de M.; CANESIN, R. C.; BONILHA, S. F. M.; BERNDT, A.; FRIGHETTO, R. T. S.; MAGNANI, E.; BRANCO, R. H. Residual feed intake (RFI) is an attractive measure of feed efficiency, as it does not depend on body size, growth rate, or body composition measures (Durunna et al., 2012). High-efficiency animals ex... ... Repository: BDPA Publication year: 2015
Bayesian inference in genetic parameter estimation of visual scores in Nellore beef-cattle. Author(s): FARIA, C. U. de; KOURY FILHO, W.; MAGNABOSCO, C. de U.; ALBUQUERQUE, L. G. de; BEZERRA, L. A. F.; LÔBO, R. B.
