Development of tongue-playing in artificially reared calves: effects of offering a dummy-teat, feeding of short cut hay and housing system (1998)

Seo, T., Sato, S., Kosaka, K. et al.

Abstract

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 (consisting of tongue-playing and para-tongue- playing). .. Feeding of short cut hay did not lead to inclusive tongue-playing. Inclusive tongue-playing appeared more in individual-housed than group-housed calves. Calves spent less time suckling, feeding, exploring and moving in individual-housing than group-housing in this study condition.
