Correlation among carnosine content, MDA, SOD, CAT, and pH of longissimus dorsi muscle in finishing pigs

Index	MDA	SOD	CAT	LDH	pH45 min	pH24 h	pH48 h
Carnosine	−0.52**	0.39	0.43*	−0.26	0.07	0.21	0.06

MDA, malondialdehyde content in longissimus dorsi muscle (n = 8); SOD, superoxide dismutase activity in longissimus dorsi muscle (n = 8); CAT, catalase activity in longissimus dorsi muscle (n = 7); LDH, lactate dehydrogenase activity in longissimus dorsi muscle (n = 8). pH, muscle pH (n = 8); CARNS1, Carnosine: carnosine content in longissimus dorsi muscle (n = 7–8 [correlation between carnosine and CAT, n = 7; otherwise n = 8]).
