What are two exotic varieties of cows?

Two prominent exotic cattle breeds are Holstein Friesian (or Holstein) and Jersey. Holstein Friesian cattle, originating from the Netherlands, are black and white spotted and are the world's highest milk-producing breed, yielding 25-30 liters daily. Jersey cattle, from the British Isle of Jersey, are smaller, fawn-colored animals producing milk with high butterfat content (5-6%), ideal for butter and cheese production. These exotic breeds are often crossbred with indigenous cattle to improve milk production while maintaining local adaptability and disease resistance.
