The farm animals prefer face-to-face chat, new research from Austria suggests. Cows are more relaxed after being spoken to directly by a live human rather than when listening to a recorded voice via a loudspeaker, researchers found. "Our study suggests that live talking is more relaxing for our animals than a recording of a human voice," said Annika Lange, a doctoral student at the University of Veterinary Medicine in Vienna and author of the study, in a press statement. "Interactions may be less positive when they become artificial. "Previous research has shown that cows are quite sophisticated "co-moo-nicators" -- both among themselves and with humans. Scientists have discovered that cows make distinctive sounds when excited, lonely or looking forward to a meal, and they direct low-frequency calls toward their calves. Theyre also responsive to human voices. Calves can learn to be called by individual namesand have learned to follow specific calls to go to the milking shed. They also seem to show a clear preference for handlers who talk gently rather than shout. This latest study, published in the journal Frontiers in Psychology, suggests that cows prefer to listen to humans in person. Researcher Annika Lange said cows will often stretch out their necks when relaxed. Working with a herd of 28 heifers, the researchers compared stroking the animals while playing a recording of an experimenters voice talking soothingly, or stroking them while speaking to the animals directly -- also gently. "When relaxed and enjoying the interaction, the animals will often stretch out their necks as they do when they groom each other," said Lange. "Additionally, it is thought that ear positions may indicate mood: hanging ears and low ear positions appear to be linked to relaxation. "Dogs brains arent hardwired to care about human facesThe cows behavior and physiological signs suggested that the animals had a positive reaction to both the recorded and in-person talking.
