• The incidence of Porcine Stress Syndrome (PSS), determined by halothane screening, and parameters of muscle quality and carcass leanness were studied in 108 pigs from a larger population of 658 pigs of Pietrain (P), Minnesota No. 1 (M), Hampshire (H) x (P x M), Yorkshire (Y) X (P X M) and P X (P X M) breeding. The larger population was also surveyed by the halothane screening procedure for incidence of PSS, and growth rate was measured. At 6 to 14 weeks of age, pigs were classified as PSS if they exhibited muscle rigidity within 5 min after the commencement of anesthetization with 3% halothane in oxygen. The incidences noted for the larger population were: H x (P x M) and Minnesota No. 1, 0%; Pietrain, 88%; Y x (P x M), 3%, and P x (P x M), 17%. Results demonstrated that the H x (P x M) group displayed excellent carcass meatiness combined with acceptable meat quality and freedom from PSS.
