Abstract

The artificial incubation became decisive for the performance of poultry production. So, the control of all factors that surround this process is crucial for the embryonic development and, consequently, to obtain optimal responses of birth. The sound stimulus is also an influential agent in incubation, which motivates this research to investigate its action and define the effects on physiological, behavioral and production performance of broiler chicks. The project will be developed in three phases. The Phase 1 will characterize the sound of commercial hatcheries from different companies. The Phase 2 will conduct laboratory tests to define the internal sound propagation in eggs. Finally, in the Phase 3 a series of experimental incubations be performed with different sound stimulation treatments. There will be a 3 x 2 factorial, considering three types of sound (vocalizations of the species, noise of machinery and classical music) and two sound pressure levels (65 and 110 dB). Three sets of responses will be evaluated in the post-hatching and 24, 96 and 168 hours after the outbreak: (A) productive performance of incubation (hatchability and mortality rates; quality and birth weight of birds); (B) physiological performance in the post-hatching and the first week of bird life (organ weights, brain development and levels and corticosterone); (C) behavioral performance (tests of fear and perception of the environment) and productive in the first week of life (weight gain).
