This study aimed to estimate the energy requirements for maintenance and gain of Japanese and European quails under growth housed in two rearing systems: floor pens and cages. To determine maintenance requirements, two experiments were conducted with birds housed in cages in environmental chambers (experiment 1) and in floor pens at room temperature conditions (experiment 2). The experimental design was completely randomized with four levels of feed supply (100, 75, 50 and 25%) and four repetitions. Energy requirements for maintenance […]
