Four feeding schedule were investigated for broiler breeders: at 6:30 am; 50% feeding at 6:30 am and 50% at 3:30 pm (dual); at 11:00 am, and at 3:30 pm. Arbor Acres breeders were randomly assigned to 48 boxes, with 12 replicates of 27 females and three males each. The nutritional levels and management procedures were those recommended for strain. The variables studied were: total egg production, nest, clean and broken egg production, in six collections (6:30 am, 9:00 am, 11:00 […]
