The present study was aimed to elucidate the proper age when the ducklings could be free-ranged in paddy fields under the rice-duck farming system. Bathing time, body temperature and wetness of feathers in the water of 3 kinds of ducklings (Indian Runner: IR, Chinese native: CN and Crossbred ducks: Fsub(1)) under a forced bathing (water temperature 20 deg C or 5 deg C, up to 60 minutes) were compared. The results obtained were as follows: 1) There was no significant difference in bathing time among the 3 kinds of ducklings at 0 d of age. The bathing time of ducklings gradually decreased over 0-12 d of age. The bathing time of Fsub(1) at 3, 6 and 9 d of age was significantly longer than those of IR and CN (P0.05). There was no difference in bathing time whether the water temperature was 20 deg C or 5 deg C. 2) The drops in body temperature of Fsub(1) and CN after bathing at 0 d of age were significantly smaller than that of IR (P0.05). The differences in wetness of feather of the ducklings during 0-12 d of age were not significant among the 3 kinds. These results indicated that Fsub(1) had a higher bathing ability compared to CN and IR.
