Effect of porcine stress syndrome on the solubility and degradation of myofibrillar/cytoskeletal proteins
Article Abstract:
Porcine longissimus muscles were removed 45 minutes after slaughter, stored and examined postmortem to determine the effect of stress classification on protein solubility and degradation. There was decreased sarcoplasmic and myofibrillar protein solubility with stress positive as compared with stress negative and carrier pigs. Postmortem degradation of structural proteins is also delayed. This is similar to attributes found in pale, soft and exudative muscle which is characteristic of porcine stress syndrome.

Effect of wavelength on spatial measurements of light scattering for the measurement of pork quality
Article Abstract:
A study was conducted to determine whether the wavelength of a helium-neon red laser is at or near the optimum wavelength for reliable measurement of meat quality. Pork of different qualities over a range were selected from a commercial abbatoir and analyzed with spatial scanning and spectrophotometric methods. The results showed that that red laser is a reliable measure of pork quality since its wavelength (633 nm) is close to the optimum wavelength of meat quality measurements.

Effect of a hot environment on performance, carcass characteristics, and blood hormones and metabolites of pigs treated with porcine somatotrophin
Article Abstract:
A study was conducted to assess the interaction of porcine somatotrophin and environmental temperature on performance, carcass traits, hormonal and metabolite functions in pigs. Forty pigs, kept in either thermoneutral or hot environment conditions, were implanted with 100 milligram recombitant procine somatotrophin (rpST). No interaction between temperature and hormone was found and the effects of rpST were equally evident in pigs exposed to thermoneutral and hot conditions.
