AMBIGAINE : UN OUTIL D'AIDE AU PERCEMENT DES GAINES DE BRASSAGE EN SALLE DE GAVAGE

Abstract : The thermal comfort of poultry depends on the effective temperature (ET) experienced by the animal. It integrates the components of temperature, humidity and air velocity in their living area. Sustainability and animal welfare studies by the production chain has favored the choice of blowing ducts in gavage housing. This choice induced the need to better control the distribution of air speed in gavage rooms. A calculation tool was implemented for production organization technicians and feeders with two functions. The first makes it possible to realize a drilling plane of a new duct adapted to obtain the desired air velocities over all the housings of the row, the second, oriented to the diagnosis and the tool improvement, makes it possible to compare observed air velocities to the values simulated in the house with a given drilling. A series of measurements were carried out on 2 configurations of ducts fitted to an experimental gavage room. The observations made associated with the characteristics of the ventilators made it possible to establish an Excel® tool for a calculation of the air velocity in the dwellings. The calculated data were compared with the measured data. The mean velocities are correctly predicted (0.5 m/s) but the calculation does not account for fluctuations in velocity over time. At the maximum fan power these one exceeds 1 m/s. The tool thus produced visually returns, with a mesh size of 10 cm, the air velocities obtained in the form of surfaces colored according to the calculated speed level. The outputs of the tool, discussed with the technicians of production organizations provide the elements of response to the optimization of the ventilation ducts in the gavage room.
