The present study examined the effect of temperature of wet feed on the feeding behavior, growth and digestibilities of piglets fed under the natural temperature condition. Three hogs and 6 female piglets (crossbred: Dekalve) were used. The feeds with different temperatures (15, 20 and 25 degrees C) were prepared, of which ratio of water to feed was 2 : 1. The piglets were divided into three groups equally. They were penned individually and the feed, which was equivalent to 6-8% of body weight per day, was provided twice a day. Growth test was carried out from 35 days old to 75 days old, and the feeding behavior was observed for 5 days at the following mean body weight: 10, 20 and 30kg. Digestibility was determined with the indicator method of Cr2O3 from 28th to 32nd day of the experiment. Environmental temperature changed in the range of 17 to 25 degrees C, and the mean temperature was 21.6 degrees C. Body weight gain and feed intake amount of 15 degrees C treatment group tended to be higher than the other 2 groups. Feed efficiencies of 15 and 20 agrees C treatment group showed the significantly higher values than that of 25 degrees C treatment group. Feed intake time and feed intake amount/min. showed short time and high level, respectively, in 15 and 20 degrees C treatment groups at each growth stage. Digestibility was not affected by feed temperature
