M. N. Bonin, Ferraz, J. B. S., Eler, J. P., Rezende, F. M., Cucco, D. C., Carvalho, M. E., Silva, R. C. G., Gomes, R. C., and Oliveira, E. C. M., “Sire effects on carcass and meat quality traits of young Nellore bulls”, vol. 13, pp. 3250-3264, 2014.

Meat quality is being increasingly demanded by consumers in recent years. Several factors can affect meat quality, ranging from animal traits such as breed and genetic heritage to pre- and post-slaughter processes. This study investigated the influence of Nellore bulls on carcass and meat quality traits. We used 475 young uncastrated males, the progeny of 54 bulls, to evaluate characteristics of the following carcass traits: hot carcass weight, rib-eye area, and fat thickness.

Association of T1740C polymorphism of L-FABP with meat quality traits in Junmu No. 1 white swine

This study was designed to investigate a single nucleotide polymorphism in intron 1 of the liver fatty acid-binding protein (L-FABP) gene in 156 Junmu No. 1 white swine using PCR-single-strand conformational polymorphism. The association between the polymorphism and meat quality traits was also studied. The cloning and sequencing results indicated that the polymorphism in intron 1 was due to a T→C mutation at position 1740 of L-FABP, yielding three genotypes (TT, TC, and CC).
