| Three experiments were carrie out to evaluate the influence of cage density on the performance of 25- to 84-week-old laying hens. Forty hundred Lohmann-LSL layers were distributed in cages (100x40x 45x50cm) according to a completely randomized experimental design with split plot in time.Three treatments (10, 12, or 14 hens per cage, corresponding, to 450, 375, and 321cm²/bird, respectively), with 15 assessment periods (four weeks each), and eight replicates per treatment were applied. Considering that layer's production cycle is affected by age, three experimental trials (25 to 44; 45 to 64 and 65 to 84 weeks of age) were carried out, and the data collected in each trial was individually analyzed. Increasing cage density significantly reduced feed intake... |
