Effect of an evaporative cooling and dust control system on rearing environment and performance of male broiler chickens.
An experiment was conducted to determine the effect of a micromist, high pressure, evaporative cooling and dust control system on rearing environment characteristics and performance of broiler chickens. Air of rearing chambers with the cooling and dust control system had significantly lower dust concentrations than that of chambers without the system. Birds reared with the cooling and dust control system were 45 and 165 g heavier at 4 and 7 wk of age, respectively, and had significantly higher 7-wk bursa weights than those reared without the system. Presence of the cooling and dust control system had no effect on mortality or lung weights.
