A Brazilian cow named Viatina-19 FIV Mara Movés has been declared the most expensive cow ever sold at auction by Guinness World Records, with a value of $4 million. Weighing twice the average weight of its breed, the cow is valued for its muscle growth speed, fertility, and genetic traits that have been passed down. Owned by Napemo Agriculture and another rancher, the cow has won numerous prizes and has been sold in auctions where partial ownership is bought and sold. The livestock industry is a significant source of economic development and national pride for Brazil, despite claims from climate scientists that consumption of beef should be reduced due to its environmental impact.
