An experiment was conducted to investigate the effects of dietary herbal product(Miracle$^{\circledR}$) supplementation on the performance, nutrient digestibility, fecal microflora and blood parameters in pigs. Forty eight cross bred(Y${\times}$L${\times}$D) weanling pigs (average initial body weight 7.84kg${\pm}$0.17, 28 d old) were used in 35 d feeding trial. Pigs were allotted to 16 raised floor cages(W 35.5cm${\times}$L45cm${\times}$H 55cm). Each treatment had four replications of 3 pigs each. Treatments were: control (T1), CTC 100ppm (T2), Miracle$^{\circledR}$ 0.15% (T3) and CTC 100ppm + Miracle$^{\circledR}$ 0.15% (T4). The herbal product supplementation(T3) tended to improve the weight gain, feed intake, feed/gain but there were no significant differences among treatments. Nutrient digestibility was significantly(P〈0.05) affected by dietary treatments. The pigs fed T3 diet showed the lowest digestibility of DM, crude protein, NFE, P, and amino acids among treatments. Serum cholesterol level of pigs fed T3 diet was lowest and significantly(P〈0.05) lower than those fed antibiotic supplemented diet(T2). Triglyceride and HDL level of the pigs fed T3 diet were also lower than those of others but the differences were not significant. The level of serum IgG was significantly(P〈0.05) different among treatments. The level of serum IgG was highest in T4, followed by T1, T2 and T3. Serum AST(Aspartate aminotransferase) level of the control(T1) was lower than other treatments. Levels of serum total protein, albumin and ALT(Alanine aminotransferase) were not significantly different among treatments. The colony forming units (CFU) of Lactobacillus, Cl. perfringens and E.coli in feces were not significantly different among treatments but those of Cl. perfringens of T2 (CTC 100ppm) showed the lowest count at both 3rd and 5th wk. It is concluded that herbal product Miracle$^{\circledR}$ does not significantly affect growth performance of weanling pigs but it influenced the digestibility, serum IgG, cholesterol and AST level. The combination of the herbal product Miracle$^{\circledR}$ with antibiotic(CTC) showed no synergistic effects.
