Like humans dairy cows must produce young in order to lactate. Every year these mums give birth to a calf. If she gives birth to a male calf like Louis, these babies are considered a waste product to the industry as males are unable to produce milk. Mum and calf are separated soon after the birth.
Every year around 700,000 male or bobby calves are slaughtered in Australia before they are a week old.
Louis and his friends are among the very few lucky ones who were saved from slaughter.
