  • This study was conducted to investigate the effect of dietary mugwort pelleted on the storage stability of pork. barrow (T1) and boar (T2) were alloted into six treatments: 1) control (commercial feed) 2) T1-1 and T2-1(commercial feed supplemented with 3.0% mugwort pelleted) 3) T1-2 and T2-2 (commercial feed supplemented with 5.0% mugwort pelleted). They were fed with the experimental diets for 60 days and slaughtered. Meat samples were in wrap package and stored at 4${\pm}$1$^{\circ}C$ for 10 days. pH, WHC and cooking loss were not siginificanly different in all treatment. But these values were tended to increase during storage for all treatment groups (p<0.05). Thiobarbituric acid reactive substances (TBARS) and Volatile Basic Nitrogen (VBN) values were low for pork samples prepared from pigs supplemented mugwort pelleted diet and the values were increased as storage period increased for all treatment groups (p<0.05). But L value was highest for pork samples prepared from pigs supplemented of 3.0% mugwort pelleted diet among treatments group.

  • Effect of fish oil and mugwort pelleted on meat quality in 40 pigs was investigated. The pigs were randomly assigned to one of the four dietary treatments : 1) Control (commercial feed 2) T1 (commercial feed supplemented with 1% fish oil and 1% mugwort pelleted 3) T2 (commercial feed supplemented with 1% fish oil and 3% mugwort pelleted) 4) T3 (commercial feed supplemented with 1% fish oil and 5% mugwort pelleted). The weight gain was not significantly difference between control and treatment groups(p<0.05). In proximate composition, crude fat of pork from treatment groups were decreased by addition level increased than that of control (p<0.05) but moisture crude protein and crude ash was no significantly difference. The total cholesterol, HDL-C and triglyceride of treatment groups was higher than that of control. LDL-C of control was higher than that of treatment groups. The pH, WHC (water holding capacity) and shear force of treatment groups were higher than control group. Especially pH, WHC and shear force was higher in T3 than other treatment groups (p<0.05). The meat color of treatment groups showed whiter than that of control group owing to higher $L^*$ value. The hardness and flavor of sensory evaluation were improved by treatments, especially in T2 and T3 (p<0.05).

  • To investigate the effect of dietary mugwort pellet on the growing performance and meat quality barrow (T1) and boar (T2) were alloted into six treatments : 1) commercial feed, 2) T1-1 and T2-1 (commercial feed supplemented with 3.0% mugwort pellet), 3) T1-2 and T2-2 (commercial feed supplemented with 5.0% mugwort pellet). They were fed experimental diets for 60 days before slaughtered. Meat samples were taken in wrap package and stored at 4$\pm$1$^{\circ}C$. Daily gain in both groups (T1 and T2) were higher than those of the control (p<0.05). Feed conversion tended to be lower in barrow group than boar group and tended to be decreased according to supplementation of mugwort pelleted diet in barrow group. In both barrow and boar groups, proximate compositions of pork were not sigificantly different, except for crude fat. Crude fat content was tended to be low in barrow when fed mugwort pelleted diet. Shear force value and sensory properties were siginificantly higher in barrow group than in boar group (p<0.05) and these results were also seemed due to great fed mugwort pelleted aiet(p<0.05). In the barrow group, values of tenderness and flavor were the highest in pigs fed diet supplemented with 3.0% mugwort. The catechin content of pork tended to be higher in boar group than in barrow group and catechin tended to increase with supplementation of mugwort in the diet.
