Interaction of dietary vitamin D3 and sunlight exposure on B. indicus cattle: animal performance, carcass traits, and meat quality. Author(s): LOBO-JR, A. R.; DELGADO, E. F.; MOURÃO, G. B.; PEDREIRA, A. C. M. S.; BERNDT, A.; DEMARCHI, J. J. A. A. Attempts to improve beef tenderness through supplementation with dietary vitamin D3 have been challenged by null results and negative impacts on animal performance and carcass traits. Because vitamin... ... Repository: BDPA Publication year: 2012
Calcium and potassium content in beef: influences on tenderness and associations with molecular markers in Nellore cattle. Author(s): TIZIOTO, P. C.; GROMBONI, C. F.; NOGUEIRA, A. R. de A.; SOUZA, M. M. de; MUDADU, M. de A.; THOLON, P.; ROSA, A. do N.; TULLIO, R. R.; MEDEIROS, S. R. de; NASSU, R. T.; REGITANO, L. C. de A. Calcium (Ca) and potassium (K) are essential nutrients in animal nutrition. Furthermore, the Ca content can influence meat tenderness because it is needed by the proteolytic systemof calpains and calp... ... Repository: BDPA Publication year: 2014
Refinamento de uma região de QTL associada à maciez de carne em bovinos da raça Nelore. Author(s): DINIZ, W. J. da S.; TIZIOTO, P.; MOKRY, F. B.; MUDADU, M. de A.; REGITANO, L. C. de A. Meat tenderness is the key factor for consumer acceptance. It is known that this trait is at least moderately heritable, so the understanding of its genetic architecture can contribute to the developm... ... Repository: BDPA Publication year: 2014
Identification of KCNJ11 as a functional candidate gene for bovine meat tenderness. Author(s): TIZIOTO, P.; GASPARINI, G.; SOUZA, M. M.; MUDADU, M. de A.; COUTINHO, L. L.; MOURÃO, G. B.; THOLON, P.; MEIRELLES, S. L. C.; TULLIO, R. R.; ROSA, A. do N.; ALENCAR, M. M. de; MEDEIROS, S. R.; SIQUEIRA, F.; FEIJO, G. L. D.; NASSU, R. T.; REGITANO, L. C. de A. The potassium inwardly rectifying channel, subfamily J, member 11 (KCNJ11) gene was investigated as a candidate for meat tenderness based on the effects reported on muscle for KCNJ11 gene knockout in... ...

MyoD1 expression levels affect meat tenderness in Nellore beef cattle. Author(s): TIZIOTO, P. C.; GASPARIN, G.; COUTINHO, L. L.; MOURÃO, G. B.; MUDADU, M. de A.; SOUZA, M. M.; MALAGO JUNIOR, W.; DONATONI, F. A. B.; TULLIO, R. R.; NASSU, R. T.; REGITANO, L. C. de A. The MyoD1 gene play a key role in skeletal muscle differentiation through the regulation of muscle-specific genes expression. Repository: BDPA Publication year: 2014
Utilização de ferramentas genômicas na caracterização e seleção genética para maciez da carne em bovinos nelore mocho. Author(s): MAGNABOSCO, C. de U.; CASTRO, L. M. de; LOPES, F.

Genetic correlations estimate between meat tenderness, growth and carcass traits in a population of polled nellore cattle in Brazil. Author(s): CASTRO, L.; MAGNABOSCO, C. de U.; GONZALEZ, R. D. S.; FARIA, C.; LÔBO, R.; NAKAGAWA, A.; LOPES, F. Growth, carcass and tenderness data from 415 Polled Nellore animals were analyzed in order to estimate the genetic correlations between tenderness (WBSF) and growth (ILW, FLW and ADG) and carcass (BF,... ...

MiRNAs differentially expressed in skeletal muscle of animals with divergent estimated breeding values for beef tenderness. Author(s): KAPPELER, B. I. G.; REGITANO, L. C. de A.; POLETI, M. D.; CESAR, A. S. M.; MOREIRA, G. C. M.; GASPARIN, G.; COUTINHO, L. L. MicroRNAs (miRNAs) are small noncoding RNAs of approximately 22 nucleotides, highly conserved among species, which modulate gene expression by cleaving messenger RNA target or inhibiting translation.... ...
