Perhaps surprisingly, there is a lot of paperwork involved with dairy farming and you'd be hard pressed to find a dairy farmer who doesn't spend a lot of time in front of a computer.

For example, farmers keep accounts of the feed and fertiliser that they use, as well as maintaining health records for individual cows and calves. Some farmers even have computerised systems tracking the milk their cows produce or the feed their calves eat.

All British dairy cows have a unique passport which can trace the animal's mother, place of birth and any movements throughout her lifetime.
