RESUMO -Um experimento foi conduzido com o objetivo de avaliar a exigência de lisina digestível para frangos de corte machos da linhagem Ross no período de 1 a 11 dias de idade. Utilizaram-se 1.050 pintos de 1 dia alimentados com cinco dietas, isoenergéticas (2.950 kcal EM/kg) e isoprotéicas (23% PB), com 1,12; 1,17; 1,22; 1,27 e 1,35% de lisina digestível, distribuídos em um delineamento em blocos ao acaso com sete repetições e 30 aves por unidade experimental.Realizou-se abate comparativo para determinar a deposição de nutrientes corporais. Observaram-se reduções lineares no peso final, no ganho de peso, no ganho de peso relativo e no consumo de alimento, o que indica provável excesso de aminoácidos na dieta. A composição química corporal não diferiu entre as aves, exceto o conteúdo de cinzas no sangue e nas vísceras, que apresentou resposta quadrática aos níveis de lisina digestível da dieta. Nas taxas de deposição de nutrientes, observou-se redução linear na deposição de água na carcaça. O nível ótimo de lisina digestível para frangos de corte machos de 1 a 11 dias de idade deve ser igual ou inferior a 1,12%, entretanto, novos estudos devem ser realizados com níveis menores.Palavras-chave: aminoácido, deposição de nutrientes, exigência, nutrição Digestible lysine levels in male broiler chicken diets from 1 to 11 days of age: performance and body composition ABSTRACT -An experiment was carried out to evaluate digestible lysine requirement for male broilers chicks of Ross line from 1 to 11 days old. A total of 1050 one day old male chicks were fed with five isoenergetic (2,950 kcal ME/kg) and isoproteic (23% CP) diets, with digestible lysine levels of 1.12, 1.17, 1.22, 1.27 and 1.35%. A completely randomized bloc design was used with seven replications of 30 birds per experimental unit. A comparative slaughter technique was conducted to determine body nutrients depositions. A decreasing linear effects in final weight, weight gain, relative weight gain and feed intake were observed suggesting a probable amino acid excess in diet. The body chemical composition did not differ among birds, except for blood and offal ashes content, whish shown a quadratic response to digestible lysine levels in the diets. A decreasing linear response was observed for carcass water deposition. The best digestible lysine level for broilers from 1 to 11 days old must be equal to or lower than 1.12%, however further researches must be conducted with lower levels.

“…Lean meat content (kg) at the start (±20 kg live weight) was estimated at 45% of the live weight. 12 Average lean meat gain (kg d −1 ) was then calculated as (lean meat at slaughter (kg) -lean meat at start (kg))/(number of days between start and slaughtering).…”

“…The empty body is defined as the difference between BW and gut content (including urine content of the bladder). Empty body water (EBW) was calculated from TBW by assuming 155 g gut content/kg BW 0.75 (Susenbeth and Keitel, 1988) and the water concentration of gut content with 82% (Houseman and Mc Donald, 1976). The concentrations of fat free substance (FFS) and body protein (BP) were calculated as follows: FFS (%) = EBW (%)/82.43 BW − 0.0219 , and BP (%) = FFS (%) × 0.1402 BW 0.0940 (Susenbeth, 1984).…”
