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.
It should be recognized that the range of motion (ROM) of joints is not exactly the same among reporting authorities. For example, the reported normal flexion of the lumbar spine may vary between 80Â° and 100Â°.The value cited below is 90Â°, but 80Â° flexion should not interpreted as abnormal. The range of ânormalâ motion also decreases with age, particularly in the spine.t should also be pointed out that the maximum possible range of motion of the spine or peripheral joints is not necessarily required for ânormalâ function in the sense of being able to perform the majority of work or daily living or hobby tasks without significant restriction. Cervical Spine. Forward Flexion 40 â 60Â°.
