Proteome Profiles of Longissimus and Biceps Femoris Porcine Muscles Related to Exercise and Resting
Proteome Profiles of Longissimus and Biceps Femoris Porcine Muscles Related to Exercise and Resting
摘要
Exercise affects muscle metabolism and composition in the untrained muscles. The proteome of muscle tissue will be affected by exercise and resting. This is of economic importance for pork quality where transportation relates to exercise of untrained muscles. Rest reverses exercise effects. The objective of this research was to develop potential protein biomarkers that predict the optimal resting time after exercise related to optimal pork quality. Ten litters of four female pigs were within litter allocated to the four treatment groups： exercise by running on a treadmill for 27 minutes followed by rest for 0, 1, or 3 h; control pigs without exercise. Proteome profiles and biochemical traits measuring energy metabolism and meat quality traits expected to be related to exercise were determined in the Longissimus and the Biceps femoris of the pigs. The results indicated associations between protein abundances in muscles and exercise, resting, and biochemical traits.
