Effects of slatted floor temperature on performances of lactavting sows were studied in sows. The animals divided into 3 group and randomly kept in farrowing pens which the slatted floor on sow section were adjusted to be normal (Group 1), 25 deg C (Group 2) and 20 deg C (Group 3) by circulating cold water pass through the water tube embedded in the slatted floor. However, the actual temperature of the floor were 28.68, 28.57 and 25.72 deg C for Group 1, 2 and 3, respectively. The sows were stayed in the farrowing pens from day 107 of gestation until day 28 of lactation. The animals were fed 4 times daily, 2 times in the morning and 2 times in the afternoon. Under the condition of the study slatted floor temperature had no effects on feed intake, body weight and backfat thickness loss during lactation, weaning weight of the piglets, the weaning to estrus interval and percentage piglets loss during lactation (P0.05). Sows on Group 1 could manage the water from drinker to wet the floor and kept the floor temperature down. In addition, feeding of the sows 4 times daily stimulated the feed intake and over come the effects of slatted floor temperature in the study. Floor temperature neither influence the skin and rectal temperature of the sow. However, there is a tendency that the cooler slatted floor decrease skin and rectal temperature of the sows.
