Vegetarianism
Dairy and eggs

One of the main differences between a vegan and a lacto-ovo vegetarian diet is the avoidance of both eggs and dairy products such as milk, cheese, butter and yogurt. Ethical vegans do not consume dairy or eggs because they state that their production causes the animal suffering or a premature death.

To produce milk from dairy cattle, farmers separate calves from their mothers soon after birth to retain cow milk for human consumption.
