Resumo
This research had the objective of evaluating the performance
and nitrogen balance of commercial laying hens between 25 and 44 weeks of age, fed diets
containing different levels of digestible lysine (0.700, 0.800 and 0.900%) and combined with
digestible threonine (0.500, 0.550 and 0.600%). The diets contained 16% crude protein. A
randomized experimental design was used in a 3x3 factorial scheme (three levels of lysine x
three levels of theronine), with five replicates. The experiment unit consisted of a cage with
eight hens. Data were submitted to analysis of variance using the statistical software SAS.
The different levels of lysine and theronine did not influence (p > 0.05) production, weight
of the eggs and nitrogen balance. An interaction was verified between the levels of lysine
and theronine (p < 0.05) in the diets regarding feed conversion (kg kg-1). The levels of
0.800 and 0.550% of digestible lysine and threonine, respectively, enhanced the feed
conversion (kg kg-1) in diets of hens.
