Dutch dairy cows are cheap mainly because the Netherlands is one of the world's largest exporters of dairy products, and its dairy exports account for nearly 10% of the global total.

Secondly, the Netherlands has the most efficient animal husbandry and dairy farming technology in the world, which makes the cost of raising dairy cows relatively low and can also produce high-quality dairy products.

In addition, the Dutch government's support and supervision of the dairy industry is also very strict, ensuring the safety and quality of milk. Therefore, the price of Dutch dairy cows is relatively low, but their quality and output are very high.
