HOW SMART ARE CATTLE?
Animal researchers are providing scientific proof that cattle are able to solve problems. Applied Animal Behavior Science reports on a Cambridge University study in which Holstein-Friesian dairy heifers ages 7 to 12 months were divided into two observation groups. The first group had to press a panel with their noses to open a gate that led to food. The second group did not have to press the panel; the gate was controlled automatically and opened without their pressing. The heart rates of individuals in each group was measured. The heart rates of the “pressing” group increased when they were successful in opening the gate. In its analysis of the experiment and its results, Psychology Today observed that this study suggests that “cows and probably other animals” can have “eureka” moments, giving them pleasure in learning.
