After calving, it takes 60 to 90 days for cows to resume cycles. This period is called postpartum anestrous. In first calf heifers, postpartum anestrous lasts longer than mature cows. It normally takes 90 to 120 days for first calf heifers to resume cycles.
The Story of Bottled Water. The Story of Bottled Water, released on March 22, 2010 (World Water Day), employs the Story of Stuff style to tell the story of manufactured demandâhow you get Americans to buy more than half a billion bottles of water every week when it already flows virtually free from the tap.
Sources [edit]. About 25% of U.S. bottled water sold is purified municipal water according to a four-year study by the Natural Resources Defense Council (NRDC). Both Aquafina from PepsiCo and Dasani from The Coca-Cola Company originate from municipal water systems.
