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.
For the first four or five days the lambs will need feeding every 4 hours, after this period that can increase to 6-8 hours until weaning. The initial amount of milk can gradually be increased from 1 pint up to 3 pints at weaning.
