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 resting period, which may range between 10 to 30 minutes, depending on the lamb cut, allows the juices to be distributed evenly throughout the meat and allows the internal temperature to rise because of the residual heat.
