extending posterior of approximately
the 10th thoracic vertebra, for 6 h. Lambs in the RISonly
group also were being stressed at the same time.
After initiation of stressor treatments, venous blood
samples were obtained from the jugular catheters at
12-min intervals for 6 h to quantify epinephrine,
norepinephrine, and cortisol in plasma, and serum
concentrations of insulin, glucose, lactate, and free
fatty acids. Upon completion of the 6-h period of RIS,
lambs were transported less than 1 km to the Kansas
State University Abattoir and slaughtered ( 5 30 min).
