The adaptation to water and cold tolerance of goslings were investigated. 1)The time budget of bathing behaviour of the rearing goslings was significantly smaller than that of Aigamo ducklings during 2-12 d of age (P<0.05). 2)There were no significant differences in bathing time under the forced bathing treatment between Aigamo ducklings and goslings at 0 d of age. However, the bathing time of goslings at 7 and 14 d of age was significantly shorter than that of Aigamo ducklings. 3) Body temperature of goslings reached over 40℃ at 4 d of age. The drops in body temperature of goslings after exposing cold environment (10℃) for 180 min at 6 and 12 d of age were significantly smaller than that of 0 d of age. The results indicated that goslings had lower bathing ability compared to Aigamo ducklings, though thermoregulation in goslings might be well-developed at about 6 d of age.}, pages = {11--14}, title = {ガチョウ雛の水順応性および耐寒性}, volume = {39}, year = {2018}, yomi = {タカヤマ, コウジ and ホンダ, ヨシタカ and オオシマ, イチロウ and ナカニシ, ヨシタカ} }
