Megafactories: Al Marai. We go behind the scenes and uncover it takes to run the largest integrated dairy company in the world. 2 massive bottling plants and 6 Mega farms run 24 hours a day, churning out milk, yogurts, juices, and over 400 other products. Starting with a herd of 128,000 Holstein cows that pump millions of liters of milk each day, milk is processed in the factory, before being used as an ingredient in an array of different products. From the farm to the supermarket shelf, the show follows the Al Marai manufacturing process from start to finish.
