The musculoskeletal system (see Introduction to the Biology of the Musculoskeletal System) includes the bones, muscles, ligaments, tendons, and joints, which support and move the body.
Lambing. Ewes generally lamb around 145 days after mating. Some of course will be earlier & some later, but 145 days is the norm. For a successful lambing, ewes need to receive good nutrition, particularly in the last month of pregnancy when the lamb will approximately double in size.
The lamb will suckle on its mothers milk for about 4 months then they begin to eat grass, hay and grain. A ewe has a unique bleating sound in which the lamb can identify her with. The lambs will stay with their mother until they are about 5 months old. At 6 months, they are considered fully grown.
