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.
Consider the following recommendations if you plan to breed ewe lambs this fall. 1. Turn the ram in when the ewe lambs are 8-9 months old rather than 6-7 months. This will result in a higher percentage of them lambing. Some producers report having 85% or more of their ewe lambs breeding and lambing. In addition, the extra age and development will result in fewer problems at lambing time.
