Quails were housed and reared from 1-35 days of age in litter pens in a rearing house, and then were transferred to a quail layer house.
This study aimed at verifying if different beak trimming method could optimize egg production and quality by reducing stress and cannibalism among birds.
A completely randomized experimental design was used, with six treatments in a 2x3 factorial arrangement, with two beak trimming ages (14 and 21 days) and three beak trimming variants (non-trimmed, 1-3 of the beak trimmed, or ½ of the beak trimmed), with 6 replicates of 20 birds each.
Performance was evaluated by feed inta...
