The dietary effects of digestible lysine and chelate zinc for male broiler chickens from 22 to 42 days of age were evaluated in two experimental assays. A complete randomized block experimental design in a 5 × 2 factorial, with five lysine levels (0.841, 0.876, 0.997, 1.022 and 1.030%) and two levels of zinc (43 and 243 ppm) was used. In the first assay, it was used 900 birds with initial average weight 957.4 g distributed in experimental units with 30 […]
