Resumo
In this experiment, the effects of digestible lysine levels on performance, nitrogen balance and fat
digestibility in Lohmann LSL hens 16 to 25 weeks of age were evaluated. Four levels of digestible lysine (0.6, 0.7, 0.8 and
0.9% in ration) were assessed by utilizing 160 16-year-old laying hens 16 to 25 weeks of age. The diets were isonutritive with
17% CP and 2800 (pre laying) and 2750 (pre peak) kcal/kg. A completely randomized design was used with four lysine levels
assessed in four replicates. The lysine levels did not influence weight gain, feed intake, protein and energy intake, age at first
egg laying, egg production, egg weight, feed conversion indexes, egg mass, nitrogen balance or crude fat. There was positive
linear increase on lysine intake according to the dietary levels of digestible lysine. Lysine levels do not influence the
performance or the nutrients balance, and 0.6% of lysine per kilogram of feed is recommended.
