This morning, we met Sam who took us on a virtual tour of a dairy farm.
We learnt about how a dairy farm works. Did you know that the cows wear a fitness tracker so the farmer knows how many steps they do each day and how long they spend lying down and standing up. This is so that the farmer can check on the health of the animals.
We learned about how the cows are milked and that they produce up to 50 litres of milk a day!
We learned about how the cows have been selectively bred for specific desirable characteristics. These cows are bred so that they produce a lot of milk. Other cows are selectively bred for their size so that they grow big and quick or for their hardiness so that they can live in tougher weather conditions.
We also learnt about how wheat production is similar. We produce wheat that has desirable characteristics like its size and its resistance to drought.
