New research has revealed dairy calves which are fed less, complete tasks faster and remember more in pursuit of milk but miss out on play.<\/p>\n

The findings, published in the Nature journal Scientific Reports and led by the University of Bristol, shed new light on how hungry animals sacrifice play and put finding food first. But calves that were given more food were more inclined to play.<\/p>\n

Study design and methods<\/p>\n

Researchers compared the behaviour of 2 groups of calves fed different amounts daily \u2013 one on 12 litres of milk and the other on 6 litres, the normal milk quantity given in dairy farms \u2013 when asked to find milk in a maze.<\/p>\n

Results: Hunger affects play<\/p>\n

The results showed calves fed less had better recall and were quicker to complete tasks with a milk reward. By contrast, calves fed more were less engaged in the milk reward tasks and played more.<\/p>\n

Implications for animal welfare<\/p>\n

Lead author Jillian Hendricks, a PhD student at the University of Bristol Veterinary School, said: \u201cThe study is among the first to show that hungry animals will trade-off play to prioritise finding food. It expands our understanding of how hunger suppresses other competing motivations and emotions, like play opportunities.<\/p>\n

\u201cIt also paves the way for future research, exploring how animals prioritise conflicting behaviours and incentives. This is especially important for farm animals, which are often offered limited opportunity to express certain behaviours.\u2019<\/p>\n

Takeaways for dairy farmers<\/p>\n

Study co-author Dr Ben Lecorps, Senior Lecturer and Animal Welfare Scientist at the University of Bristol Veterinary School, added: \u201cThe key takeaway for dairy farmers is that the standard milk allowance for calves may disrupt other important behaviours, which indicate that they may experience hunger.<\/p>\n

\u201cThe research suggests feeding calves more may not only be beneficial as it suppresses hunger, but also because it contributes to the expression of other important behaviours like play.\u201d<\/p>\n

Although the 2 groups of 10 calves were given a different milk allowance over a 3 week period, they all went without food for 16 hours before being tested, as part of normal farm feeding practices providing 2 meals a day once at 8am and once at 4pm.<\/p>\n

Importance of play in calves<\/p>\n

Dr Lecorps added: \u201cDespite this long period without milk, calves fed more still prioritised playing. This tells us a lot about how much play matters for them.\u201d<\/p>\n
