title: Relationship between plasma somatomedin activity and levels of cortisol and free fatty acids following stress in pigs.
abstract: Somatomedin activity, cortisol and free fatty acids have been measured in the plasma of eight Pietrain pigs at various times after stress. Somatomedin activity decreased immediately, reached a minimum after 15 min and remained low throughout a 3.5 h period Cortisol levels rose to a peak after 15 min and regained normal levels after 60 min. Free fatty acid levels increased to a peak level about 3 h after stress. The possibility of inhibitors of the bioassay for somatomedin activity influencing the results are discussed.
