Abstract
A total of 120 pigs (Berkshire) were used to investigate the effect of dietary supplementation with artificial culture medium of wild ginseng (CWG) on the physico-chemical characteristics of pork About $60{\pm}3kg$ pigs were randomly assigned to 4 pens based on sex and diet (C: commercial diet feed or T: commercial diet+1 L CWG per day for 70 days). Pigs were slaughtered at approximately 110 kg live weight, and proximate composition and physico-chemical characteristics were measured in pork loin. The moisture content, hardness and chewiness of pork were higher in gilt fed CWG than in gilt fed the control diet, but the water-holding capacity of pork and $L^*$ values of fat color were lower. The shear force and $a^*$ values of pork were higher in barrow fed CWG than in harrow fed the control diet. The crude fat content, hardness, cohesiveness, chewiness of pork and $a^*\;and\;b^*$ values of fat color were lower in barrow than in gilt, but the pH was higher. These results imply that the proximate composition and physico-chemical characteristics of pork could be affected by dietary supplementation with CWG and the sex of the pig, while the texture properties and at values of pork may be improved with dietary CWG.
