Differential expression of the MHM region and of sex-determining-related genes during gonadal development in chicken embryos. Author(s): CAETANO, L. C.; GENNARO, F. G. O.; COELHO, K.; ARAÚJO, F. M.; VILA, R. A.; ARAÚJO, A.; BERNARDO, A. de M.; MARCONDES, C. R.; LOPES, S. M. C. de S.; RAMOS, E. S. The chicken (Gallus gallus) embryo has been used as a classic model system for developmental studies because of its easy accessibility for surgical manipulation during embryonic development. Sex deter... ... Repository: BDPA Publication year: 2014
Genome-wide characterization of genetic variants and putative regions under selection in meat and egg-type chicken lines. Author(s): BOSCHIERO, C.; MOREIRA, G. C. M.; GHEYAS, A.; GODOY, T. F.; GASPARIN, G.; MARIANI, P. D. S. C.; PADUAN, M.; CESAR, A. S. M.; LEDUR, M. C.; COUTINHO, L. L. Abstract: Background Meat and egg-type chickens have been selected for several generations for different traits. Artificial and natural selection for different phenotypes can change frequency of genet... ... Repository: BDPA Publication year: 2018
Use of statistical models to determine the optimal concentration of metabolizable energy for growth performance of broiler chickens. Author(s): MARX, F. O.; ALVAREZ, M. V. N.; BASSI, L. S.; FÉLIX, A. P.; KRABBE, E. L.; OLIVEIRA, S. G.; MAIORKA, A. Abstract: The formulation of diets that adequately meet energy requirements in the different phases of broiler chicken production is of the utmost importance. The objective of this study was to determ... ... Repository: BDPA Publication year: 2023
Innate immunity in chicken lines developed by Embrapa Suínos e Aves: antimicrobial activity of macrophages and serum. Author(s): SILVA, M. C. da; COSTA, I. C.; NAKAZATO, G.; PINHEIRO, J. W.; LEDUR, M. C.; LOYOLA, W.; VENANCIO, E. J. Abstract: The objective of this study was to compare the antimicrobial activity of macrophages and serum in laying hen (MM, CC, and CCc) and broiler chicken lineages (TT and LL). Macrophages were eval... ... Repository: BDPA Publication year: 2021
Proximal femoral head transcriptome reveals novel candidate genes related to epiphysiolysis in broiler chickens. Author(s): PEIXOTO, J. de O.; SAVOLDI, I. R.; IBELLI, A. M. G.; CANTAO, M. E.; JAENISCH, F. R. F.; GIACHETTO, P. F.; SETTLES, M. L.; ZANELLA, R.; MARCHESI, J. A. P.; PANDOLFI, J. R. C.; COUTINHO, L. L.; LEDUR, M. C. In order to investigate the molecular events taking place during the onset and development of the epiphysiolysis in fast-growing chickens, the present study used the RNA-Seq technology to identify dif... ...

Antimicrobial and cytotoxic bioprospection of Thymus Vulgaris and Thymol against Salmonella Enterica Serovar Heidelberg isolated in broiler chicken. Author(s): SPERANDIO, J.; BASTOS, A. P. A.; FONSECA, F. M. da; BELLAVER, F. A. V.; DAL BELLO, T. C.; KUHNEN, S.; MILLEZI, A. F. Abstract: Salmonella enterica serovar Heidelberg (SH), often isolated from broiler chicken samples, damages the entire production chain due to its high resistance in the environment. The search for su... ... Repository: BDPA Publication year: 2023
Diversity of campylobacter jejuni strains from broiler chicken farms in Brazil. Author(s): VAZ, C. S. L.; RECH, D. V.; POZZA, J. dos S.; MATTOS, G. L. M. Repository: BDPA Publication year: 2014
Identification and characterization of microRNAs expressed in chicken skeletal muscle. Author(s): ANDREOTE, A. P. D.; ROSÁRIO, M. F. do; LEDUR, M. C.; JORGE, E. C.; SONSTEGARD, T. S.; MATUKUMALLI, L.; COUTINHO, L. L. MicroRNAs (miRNAs, miRs) encompass a class of small non-coding RNAs that often negatively regulate gene expression. miRNAs play an essential role in skeletal muscle, determining the proper development... ...
