Effect of Housing and Age at Pairing on Calves' performances in Simple Cognitive Task
Some studies indicated that individual housing of calves impairs their cognitive abilities compared with pair housing. It is also not clear whether age at their pairing affects the cognitive abilities. We aimed at examining cognitive abilities of heifers housed in pairs or individually in a simple cognitive task. We found no effect of the individual versus pair housing or age at pairing on the number of training sessions necessary to reach the respective criteria. We conclude that pair housing does not improve performance of calves in this simple cognitive task.
