Calves are not that stupid
A total of 18 Holstein calves from the tender age of three weeks were held partly individually, partly in pairs. During a test, the scientists put an unknown red bucket in the barn. Result: The calves of the group, after a few repetitions, lost their curiosity for the red thing; on the other hand, the individual animals were still as curious after two days as at the beginning of the experiment.Grips to the Milk Reward
Test Two included the Reward Principle : There was milk from the bottle twice a day, but: The bottle in front of the white wall was full, the bottle against the black wall was empty. In the beginning, all calves had their problems with this tricky task, but the paired kites had bowed out after a certain amount of training time and assigned the full bottle to the corresponding wall paint. The individual animals, however, did not manage to meet this challenge.
Scientists' conclusion: It is better for the development of the calves if the non-weaned calves are housed in twos and threes because they learn from each other and from each other. Text/Photo: Marion Friedl
