Resumo: | The aim of this study was to determine the nutritional requirement of digestible lysine and metabolizable energy on carcass yield and protein and fat deposition rates of broilers in the period 35-49 days old. A total of 768 Cobb male broilers were distributed in a completely randomized design, in a 4x4 factorial arrangement, totaling 16 treatments (4 levels of digestible lysine x 4 levels of metabolizable energy) and three replicates of 16 birds each. The digestible lysine and metabolizable energy levels were: 0.800, 0.900, 1.000 and 1.100% and 3000, 3120, 3240 and 3360 kcal.kg-1, respectively. The different levels of metabolizable energy and digestible lysine did not influence (P> 0.05) the carcass yield, parts (breast, thigh, drumstick and wing) and abdominal fat. There was an interaction (P <0.05) between the levels of metabolizable energy and digestible lysine on protein and fat deposition rates and carcass fat of broilers. The rate of fat deposition showed the best result for the level of 1.000% LD and 3000 kcal.kg-1 ME. The higher fat content occurred in the treatment with the highest level of metabolizable energy (3360 kcal.kg-1).The metabolizable energy and digestible lysine levels contained in the diets of broilers in the period 35-49 days of age, do not interfere in the carcass and amount of abdominal fat. |

Foram utilizados 768 frangos machos da linhagem Cobb 500, distribuídos em um delineamento inteiramente casualizado, em arranjo fatorial 4x4, contendo 16 tratamentos (4 níveis de lisina digestível x 4 níveis de energia metabolizável) e três repetições com 16 aves cada. Os níveis de lisina digestível e de energia metabolizável foram: 0,800; 0,900; 1,000 e 1,100% e 3000; 3120; 3240 e 3360 kcal.kg-1, respectivamente. Os diferentes níveis de energia metabolizável e lisina digestível não influenciaram (P>0,05) o rendimento de carcaça de cortes (peito, coxa, sobrecoxa e asa) e de gordura abdominal. Houve interação (P<0,05) entre os níveis de energia metabolizável e lisina digestível sobre as taxas de deposição de proteína e gordura e o teor de gordura na carcaça dos frangos de corte. A taxa de deposição de gordura apresentou o melhor resultado para o nível de 1,000 % de LD e 3000 kcal.kg-1 de EM. O maior teor de gordura ocorreu no tratamento com o maior nível de energia metabolizável (3360 kcal.kg-1). Os níveis de energia metabolizável e lisina digestível, contidos nas dietas de frangos de corte, no período de 35 a 49 dias de idade, não interferem no rendimento de carcaça e na quantidade de gordura abdominal.UEL2015-04-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionRevisão de Literaturaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1621710.5433/1679-0359.2015v36n2p1079Semina: Ciências Agrárias; Vol. 36 No. 2 (2015); 1079-1090Semina: Ciências Agrárias; v. 36 n. 2 (2015); 1079-10901679-03591676-546Xreponame:Semina.
