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.
Sometimes bottled water is a useful temporary alternative until a new permanent water supply can be secured. The cost of bottled water in 1988 was about $7 to $15 per week for a family of four, assuming each person used 2 liters per day for drinking water only. The cost to hook up to a public water supply will depend on the distance to a water main, the housing density in the area, and water payments.
