The objective of this study was to evaluate digestible lysine levels for free-range broiler hillbilly, from 28 to 56 days old. We used 720 naked neck chickens slow-growing Label Rouge strain males, distributed in a completely randomized design with six digestible lysine levels (0.800, 0.850, 0.900, 0.950, 1.000 and 1.050%), six replicates of 20 birds each. The lysine levels did not influence (P>0.05) broiler performance in accumulated periods 28-35 days, 28-42 days and 28-49 days. There was no effect (P>0.05) of treatments on feed intake and feed conversion in the total periods (28-56 days). Effect was observed (P0.05) for carcass and breast weights of abdominal fat, thigh + drumstick, back, wing and fat deposition between the levels of lysine.(AU)
