Morrison et al. (1972), Hsia, Fuller & Koh (1974), and Ho & Khoo (1977) showed that sprinkling can alleviate the adverse effects (Straub et al. 1976) of high ambient temperature on feed intake and growth of pigs. Vajrabukka, Thwaites & Farrell (1986) demonstrated that pigs need to be thoroughly wet by sprinkling at least once every 60 min if high evaporative rates are to be maintained, but little is known of the relative benefits of different sprinkling regimes for pigs growing at high temperatures.
