Sensory factors involved in the newly born lamb's initial search for the teat.
Sensory stimulation involved in the newborn lamb's search for the teat was investigated using video tapes of newborn Clun Forest and Soay lambs. Tactile stimulation evoked movements of the head, face, jaw and tongue. Teat-seeking behaviour in lambs removed from their dams at birth differed in response to odours of inguinal wax, wool and milk from their own or alien dams. A prominent source of potential olfactory stimulation was inguinal wax secreted by the ewe.
