Resumo: | This study evaluated the effect of different levels of metabolizable energy (ME) and digestible lysine (DL) on the rate of protein deposition, rate deposition body fat and intestinal morphology of broiler chicks 1 to 10 days of age. The study design consisted of 1,152 broilers, weighing 52 ± 5 g, distributed in a completely randomized, 4x4 factorial design, consisting of four levels of ME (2700; 2825; 2950 and 3075 kcal/kg) and four levels of DL (1,080; 1,187; 1,295 and 1,403%), with 16 treatments and three replicates, with 24 poultry in each experimental unit. The protein deposition rate (PDR) and fat deposition rate (FDR) were not affected (P > 0.05) by the ME, however, PDR was influenced linearly (P < 0.05) by increasing lysine. There was an interaction (P < 0.05) between the levels of ME and DL, whose increase resulted in a higher villus height of the duodenum, jejunum and a greater relation villus: crypt ratio of the ileum. Therefore, levels of DL and ME had positive effects on the intestinal development of broiler chicks in the pre-starter phase. |

Foram utilizados 1.152 pintos de corte, com peso médio de 52±5g, distribuídos em delineamento inteiramente casualizado, em esquema fatorial 4x4, constituídos quatro níveis de EM (2700; 2825; 2950; e 3075 kcal.kg-1) e quatro níveis de LD (1,080; 1,187; 1,295 e 1,403%), com 16 tratamentos, três repetições e com 24 aves ME cada unidade experimental. A taxa de deposição de proteína (TDP) e de gordura (PDR) não foi influenciada (P > 0,05) pelos níveis de EM, no entanto, a PDR foi influenciada de forma linear (P < 0,05) pelos níveis crescentes de lisina. Houve interação (P < 0,05) entre os níveis de EM e DL, cujo aumento nesses níveis proporcionaram maior altura das vilosidades do duodeno, jejuno e na relação vilo:cripta do íleo. Os níveis de lisina digestível e energia metabolizável apresentam efeito positivo sobre o desenvolvimento intestinal dos pintos de corte na fase pré-inicial.cial.UEL2016-09-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigoArtigoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2390310.5433/1679-0359.2016v37n4Supl1p2691Semina: Ciências Agrárias; Vol. 37 No. 4Supl1 (2016); 2691-2700Semina: Ciências Agrárias; v. 37 n. 4Supl1 (2016); 2691-27001679-03591676-546Xreponame:Semina.
