Teat-seeking or pre-sucking behaviour in newly-born lambs: possible effects of maternal skin temperature
1984
Abstract The possibility that thermal cues play a part in the teat-seeking behaviour of newly-born lambs was investigated. Measurements show that the external surfaces of a lactating ewe vary in temperature, highest readings being obtained from the inguinal cavity at the base of the udder. Experiments show that, before sucking, lambs stay longer in a warm compartment than in a cool one, also that they become more active when their muzzles are placed in contact with a warm smooth surface than they do when placed in contact with a cool smooth surface. The activity evoked resembles that of newlyborn lambs searching for the teat.
