This depends on what type of meat animal you are referring to. For instance, a beef steer is ready to be butchered between 18 and 24 months of age. A broiler is ready to be slaughtered at around 3 weeks of age, and a market hog at around 2 to 3 months.
It takes years.
Beavers typically grow for birth until death.
Up to eight feet.

The largest animal in the world is the blue whale. It can grow up to 108 feet long and is a filter feeding animal.

There is no minimum limit Sikhs grow their hair to - they grow it until it reached its 'natural equilibrium' and stops growing on its own.

It depends on how much flavour you want to the meat and how much meat you want. Capretto or milk fed is when goats are slaughtered at 3 to 4 months of age (at about 25 to 30 kg live weight), chevon is no longer milk fed. I send my wethers to the abattoir when they are about 25 to 30 kg but for personal consumption as I like a larger roast I wait until they are about 6 months old.
