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.
Naturally, a medium sized sheep cannot have a lamb as large as a large sheep. Secondly, a lamb grows with relative ease and speed, if fed appropriately, to 80 pounds and slightly above. I reach that weight on average between 4 and 5 month with my male market lambs.The top lambs get to 80 pounds at three and a half months.These are mostly single male lambs from adult ewes. Some lambs will need 6 or perhaps even 7 months to get to this weight. reach that weight on average between 4 and 5 month with my male market lambs.
