This study was carried out to evaluate the performance and characteristics of carcass of broiler chickens fed diets with reduced levels of CP, available P (aP) and Ca, supplemented with phytase and amino acids. The growth phases evaluated were: Phase1, 1 – 21 days old, phase 2, 22 – 42 days old. A completely randomized design was used, with the treatments constituted of five nutritional plans (NP), with six replicates of 25 birds each. The nutritional plans were: NP1 – […]
