As an example, if it were determined the daily dry matter intake of a group of 1,200 pound cow eating an average quality hay is 24 pounds per head and the hay that they are consuming is 88% dry matter, these cows would consume about 27 (24 pounds/.88) pounds per head per day on an as-fed basis.
Normal ranges of motion for the cervical spine include 50 degrees of flexion, 60 degrees of extension, 45 degrees of lateral, or side bending, and 80 degrees of rotation.ange of motion is commonly tested in the cervical spine, thoracic spine and lumbar spine. In many sports medicine clinics, range of motion in the upper and lower extremities are also tested. The measured degrees are compared with the expected norm and also from a healthy joint with an injured joint.
Full range of motion is described as being within normal limits, or WNL. Normal ROM for back flexion is 90 degrees, or bending forward to touch your feet.As with most movements, this type of flexion works in tandem with other joints, including pelvic rotation, so any limitation could arise from back or pelvis issues.ormal extension ROM in your back is limited to only 25 degrees. This range is similar to moving your trunk from the 12 o'clock position when standing upright to in between the 10 o'clock and 11 o'clock position when extended.
