Abstract

16 artificially reared Japanese Black calves were divided into 6 groups: offered a dummy teat or not; given short or long cut hay; and housed individually or in a group. Grooming as common displacement behaviour and physiological stress indicators such as plasma ACTH and cortisol concentration were measured in each treatment and the correlation between indicators and tongue-playing was investigated. Tongue-playing was performed after forced weaning at 42 days of age, a little sucking was directed towards the dummy teat. Offering a dummy-teat neither influenced the stress state of the calves nor suppressed inclusive tongue-playing. Feeding short cut hay elevated the plasma level of ACTH and cortisol at 150 days of age in calves, but did not lead to inclusive tongue-playing. Inclusive tongue-playing appeared more in individually-housed than group-housed calves and calves spent less time suckling, feeding, exploring and moving when individually housed than in group-housing.
