Heart,lung,liver,stomach,large intestine and small intestine of wild pigs captured from the Ziwulin Mountains,Gansu were measured and compared with those of Bamei,a local domestic pig breed. Each group included two males and one female with body weights ranging from 33 kg to 43 kg. In addition,feed digestion of wild and Bamei pigs were determined in two males and one female with body weights of 53 ± 2.3 kg using a total feces collection method. Results showed that only the relative weight of lung of the wild pigs (2.1%) was significantly (P<0.01) larger than that of Bamei. All the remaining measurements of wild pigs including lengths of large intestine (3.36 ± 0.38 m) and small intestine (14.15 ± 0.31 m),lumen volumes of stomach (1.82 ± 1.36 L) and large intestine (5.91 ± 1.04 L),and weights of stomach (0.38 ±0.05 kg),large intestine (0.47 ±0.04 kg) and small intestine (0.60 ±0.03 kg) were all less than those of Bamei (P<0.05). Digestive indices of wild pigs including daily digestible mass of crude protein (0.23 ±0.13 kg) and crude fiber (0.06 ±0.03 kg),percent digestibility for crude fiber (45.7 ± 1.8%) and daily intake of crude fiber (2.44 ± 0.15 kg) were all lower than those of Bamei (P<0.05). However,percent digestibilities of wild pigs for crude protein (75.9 ± 1.3%) and phosphorus (36.2 ± 2.3%) were higher than those of Bamei (P< 0.05). These results suggest a potential benefit in development of management strategies for domestic production of wild pigs.
