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.
It is more efficient to feed the lamb directly than to feed a ewe that produces milk that a lamb consumes. Early weaning generally takes place when lambs are 60 days old. Lambs should weigh at least 45 pounds at this time.Most ewes peak in their milk production around three to four weeks after the lambs are born.After that point, milk production decreases rapidly.arly weaning generally takes place when lambs are 60 days old.
