Carcass and meat quality traits in Nellore and F1 Nellore-Araguaia crosses

N. V. Costa, Aboujaoude, C., Vieira, G. S., Paiva, V. V., Neto, R. A. Moraes, Gondim, V. S., Alves, L. R., Torres, M. C. L., and Antunes, R. C., Carcass and meat quality traits in Nellore and F1 Nellore-Araguaia crosses, vol. 14, pp. 5379-5389, 2015.

We evaluated and compared carcass traits and meat quality in Nellore cattle and F1 crosses between Nellore and Araguaia, where 17 individuals were from the Nellore group and 19 were ½ Nellore and ½ Araguaia crosses. All animals belonged to the same birth season and were raised in pasture systems under the same nutritional, environmental, and management conditions.

Sire effects on carcass and meat quality traits of young Nellore bulls

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.

Identification and association of polymorphisms in CAPN1 and CAPN3 candidate genes related to performance and meat quality traits in chickens

A. M. Felício, Boschiero, C., Balieiro, J. C. C., Ledur, M. C., Ferraz, J. B. S., T. Filho, M., Moura, A. S. A. M. T., and Coutinho, L. L., Identification and association of polymorphisms in CAPN1 and CAPN3 candidate genes related to performance and meat quality traits in chickens, vol. 12, pp. 472-482, 2013.

Meat quality is an important feature for the poultry industry and is associated with consumer satisfaction. The calpain 1 (CAPN1) gene is related to the tenderness process of meat post- mortem, and the calpain 3 (CAPN3) gene plays an important role in myofibrillar organization and growth. The objective of the present study was to identify polymorphisms in these genes and to determine the association between these polymorphisms and traits of economic interest in poultry.
