The aim of the present study was to evaluate the growth performance, carcass traits, and meat quality of female broilers of four genetic lines reared for the production of griller-type chickens. A total of 960 broiler chicks was allotted in a randomized block design with four treatments and eight replicates of 30 birds per experimental plot. Each experimental treatment consisted of four different commercial lines, identified as A, B, C and D. The analyzed parameters were weight gain, feed intake, feed conversion ratio, livability, production efficiency index, carcass and cut yields, and meat quality according to breast meat color (L*, a*, b*), water-holding capacity (WHC), cooking losses, and shear force. Weight gain, feed intake, feed conversion ratio, and livability were different (p<0.05) among the lines; however, no differences were observed for the production efficiency index. Results show that lines presented similar performance; however, lines A, B, and C had a better carcass and breast yield, and line A, the best meat quality. Therefore, line A would be the most suitable for the production of griller-type chickens. 2017 artículo científico 1516-635X https://www.redalyc.org/articulo.oa?id=179750697015 en http://www.redalyc.org/revista.oa?id=1797 Revista Brasileira de Ciência Avícola application/pdf Fundação APINCO de Ciência e Tecnologia Avícolas Revista Brasileira de Ciência Avícola (Brasil) Num.1 Vol.19 |
