Resumen:
Sensitivity analyses in a mathematical model to predict the thermal environment
throughout the length of acclimatized broiler chickens housing were carried out with the goal of
evaluating the influence of several parameters that compose the model in the calculation of
temperature, relative humidity and temperature-humidity index (THI). Several climatic conditions, air
flow rate that infiltrates throughout the broiler housing (Qinf), air fluxes through the pad cooling (Qpad),
pad cooling efficiencies (Epad); lodging densities (Dens), broiler chickens body masses (Mbroilers) and
overall heat transfer coefficients of the roof (Uroof). The analysis indicates a strong response to the
outside temperature, outside relative humidity and Epad; a smaller sensitivity to the Dens and no
sensitivity to Mbroilers, Uroof and Qinf/Qpad, which is consistent with the type of system studied.
Therefore, in a commercial production system, it should consider the Epad and Dens, because they are
the variables feasible to be handled.
