  • This study was conducted to determine the effect of supplemented useful micro-organism on performance and meat quality of growing-finishing pigs for sixty days and broiler for six weeks. The pig and broiler were randomly allotted into 3 treatment; Control 0 (C), T1 (supplemented with $0.2\%$ Aspergillus terreus), T2 (supplemented with $0.2\%$ EM-pro). In total experimental period, feed conversion and dairy feed intake were tend to be higher in T2(2.09kg, 2.70kg) than others. But ADG (average daily gain) was tend to decreased n (0.78kg) according to supplemented of Aspergillus terreus diet These treatments were not significant difference. The chemical composition of pork were not significant difference except for crude fat Crude fat content was lower Aspergillus terreus treatments than others. The pH tenderness, WHC and heating loss were not significant difference in pork $(p>0.05)$. In chicken meat, heating loss and WHC of control was higher than that of T1 and n but shear value was higher in T1 and n. Values of juiciness, tenderness and flavor were improved with highly significant difference (p<0.05) in control (4.95, 4.85, 4.60) than T1 and n in pork. Although the meat color was not significant difference in pork but a and b values of control was higher than that of T1 and n in chicken meat (p<0.05).

  • This study was conducted to determine the effect of supplemented useful microorganisim on meat quality of growing-finishing pigs for sixty days and broiler for six weeks. The pig and broiler were randomly allotted into three treatment (twenty-forty heads /treatment) ; Control (0%), T1 (supplemented with 0.2%, Aspergillus terreus koji), T2 (supplemented with 0.2%, EM-pro). The amount of stearic acid of pork was highest in T1 and T2, and oleic acid was highest in control and 71 than others (p<0.05). The amount of stearic acid of the chicken was highest in control, and oleic acid was highest in T1 and T2 than the others. Total cholesterol and HDL-cholesterol in the serum of pigs were decreased with significant difference (p<0.05) in T1 (63.77 and 111.19mg/mL, respectively) than control(101.69 and 132.37 mg/mL) and those of the chicken were decreased with lower significant difference (p<0.05) in T1 (78.50 and 143.61mg/mL) than control (119.26 and 240.43mg/mL). Total cholesterol and HDL-cholesterol in the pork were decreased with lower significant difference (p<0.05) in T1 (78.53 and 119.64 mg/mL) than control (140.55 and 150.55mg/mL), and those of the chicken were decreased with lower significant difference (p<0.05) in T1 (93.35 and 72.03mg/mL) than control (111.90 and 116.88 mg/mL). From the results, the amount of total cholesterol and HDL-cholesterol in pig and chicken was remarkably changed according to supplementation of Aspergillus terreus koji which containing the produced lovastatin.
