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.
Lambing intervals of 8 months, three lamb crops every two years, is a common practice. At what age can you start breeding ewe lambs? Depending on the time of year, ewe lambs between 6-8 months may cycle, but better conception rates will be achieved at 9-12 months and the later bred ewes will grow out better.How many ewes can a Dorper ram cover?
