Where does milk come from, how it is produced and how colostrum differs from milk

Where does milk come from?

Most of us know that it comes from a cow, goat or sheep, as it is mainly from these animals that milk is obtained in our country. However, it is worth noting that in various parts of the world milk from other species is also used, such as horse or camel.

Why do animals produce milk?

To explain where milk comes from, let us first note what it is for. It is a substance produced in the mammary glands of all mammals, and its purpose is to feed the young of their own species.

Therefore, for lactation to occur, pregnancy is required. In most animals bred for this purpose, females are bred every year to ensure continuity of milking.

What is colostrum?

Right after birth, milk is called colostrum. It is very rich in nutrients, protein, minerals and antibodies, which is why it is very important for the young to drink as much of it as possible, because thanks to this they build essential immunity in their bodies.

After about a week or two, colostrum is replaced by proper milk, which depending on the species of animal has different composition and nutrient content.

Dairy products

From milk, of course, many other products can be made, such as cheese, yogurt, butter and cream.

Humans, unique in the animal world

However, it is worth noting that in the animal world, only humans consume the milk of other species. Among animals, when the young reach the appropriate age, the mother automatically begins to limit the amount of milk they drink, in order to wean them off.
