This experiment was carried out in order to evaluate performance, nitrogen and dry matter balance and morfometrical measures of broilers raised with different levels of protein and energy on pre-starter phase (1 to 7 days of age). In a completely randomized design, 336 one-day old chicks were allotted in a completely randomized design in a factorial scheme 2 x 3 (metabolizable energy 2,850 and 3,000 kcal/kg and crude protein – 20, 23 and 26%) with four replicates with 14 birds […]
