Key Laboratory for Animal Disease-Resistance Nutrition of China Ministry of Education, Institute of Animal Nutrition, Sichuan Agricultural University, Chengdu, P. R. China.

Thirty castrated Duroc × Landrace × Yorkshire (DLY) pigs were randomly divided into three groups and slaughtered at 180, 210, and 240 days of age, respectively. Here, we found that the live weight, carcass weight, carcass length, dressing percentage, eye muscle area, backfat deposit, muscle yellowness b* value, drip loss, and cooking loss increased significantly, and the muscle pH 45 min value decreased dramatically as the slaughter age of DLY pigs extended. Moreover, increasing the slaughter age of DLY pigs could obtain higher n-3 polyunsaturated fatty acid (PUFA) percentage, crude protein, essential amino acids (EAA) contents and EAA/NEAA level, and lower n-6/n-3 PUFA level and antioxidant capacity.
