A 'Fitbit' for cows is here to help farmers get more milk out of their cattle

Dairy farming is one of the biggest industries in Pakistan, with an estimated 42 billion liters of milk production per year. With approximately 63 million animals producing milk and over eight million households involved in the trade, the country ranks as the fourth-highest milk producing nation globally. Despite these rosy numbers, average milk yields per cow are abysmally low -- estimated at only four to five liters per day during the lactation cycle. This pales in comparison to the United States -- incidentally the world's highest milk producing country -- where cows yield on average 32 liters per day. The reason behind low yields boils down to primitive agricultural practices.
