Then, magma upwelling at the Mid-Atlantic Ridge began to produce oceanic crust, parting the continents to form the Atlantic Ocean. Today the Mid-Atlantic Ridge snakes down the center of the Atlantic all the way from Iceland to the Antarctic Plate and remains an active site of sea-floor spreading..
Most calves are weaned between 120 and 290 days (3 to 10 months) after birth, but most producers like to wean their calves when they're around 205 (6 months) of age.Weight is also a factor, with the minimum being generally around 132lb (60kg). This will only add to the stress of the calves during weaning time. 2  Beware of the likely reaction of the first-calf heifers. 3  They will crawl the fence if you do not make it escape proof with a couple of strands of hot electric wire or steel panels.
1 Calves are ideally weaned when they are 7 to 8 months old. 2  The right time to wean a calf depends on the condition of the cow and not the age of the calf. 3  Calves should be weaned before the condition score of the cow falls below 2,5 if adequate winter feed is available and the cows maintain their condition. The major priority in beef production is to produce as many calves as possible. 2  The main objective of weaning is therefore to enable a cow to calve every year by allowing her to regain condition after weaning. 3  Calves are ideally weaned when they are 7 to 8 months old.
