In 2021, nearly 5 million cows were farmed for their milk in New Zealand, over 4.5 million of whom gave birth to calves who were taken away within days of being born. The milk which would normally nourish and sustain their calves is instead taken to be consumed by humans. Female calves are raised by humans to one day replace their mothers in the milking shed, while male calves are often killed within a few days of being born, considered ‘waste products’ of the dairy industry.
