This heartbreaking footage was captured by the Humane Society of the United States at McArthur Dairy Farm in Florida. The video shows one of the methods used by dairy farms in order to kill male calves.

As seen, the workers shoot days-old calves in the head, then leave them to bleed in a mass grave. The worker doesn’t even make any special effort to shoot the calves in a way that will deliver a quick death. In addition, each calf only gets one bullet in order to save costs.

But why are they killing baby calves?

Since cows can only produce milk after giving birth, dairy farms have to constantly impregnate the cows. As a result, many baby calves are born. Since male calves will never make milk, they are essentially useless to a dairy farm. Some farms let the calves live for a few months in order to slaughter them for veal. Others don’t even bother and kill them when they are a few days old.
