Two experiments were carried out to evaluate different levels of digestible lysine (0.90; 1.00; 1.10; 1.20; e 1.40%) combined with zinc chelate (43 and 253 ppm) to male broiler. The considered periods were: initial phase – performance (1 to 11 days old) and nitrogen retention (1 to 7 days old). A randomized block experimental design in a 5 × 2 factorial arrangement was used. In performance assay, 7 replications and 15 birds per experimental unit was used. In the digestibility […]
