Abstract

The Yanan (YN) pig is a traditional Chinese indigenous breed that is raised in southwest China in the Sichuan Province, but there is little data on the germplasm characteristics of this breed. To evaluate carcass characteristics and meat quality of the YN pig, we compared carcass and meat quality of YN pigs and Landrace × Yanan (CY) hybrid pigs; 30 YN pigs and 30 CY pigs weighing 20 ± 2 kg were reared and slaughtered at the normal slaughter weight (100-120 kg). The carcasses were chilled and the left carcass side was dissected into bone, lean meat, fat, and skin; meat quality parameters were measured. Carcasses of YN pigs were lighter (88.85 vs 90.05 kg, P vs 77.61 cm, P vs 49.25%, P vs 27.53%, P vs 10.53%, P vs 40.23%, P vs 3.43 cm, P vs 26.91 cm2, P 1 (6.41 vs 6.17, P u (3.86 vs 3.36, P u values (40.89 vs 45.32, P vs 2.26%, P vs 3025.43 μm2, P
