Abstract

This study was conducted to evaluate the effects of dietary herbal extracts mixture on the growth rate. carcass traits and serological changes in finishing pigs. For the Exp 1, eighty Duroc(Yorkshir(Landrace pigs(81.58$\pm$3.20kg average initial body weight) were used in a 45 day experiment. Dietary treatments included 1) NC(negative control; antibiotics-free diet), 2) PC(positive control; NC diet added 0.1% of chlortetracycline), 3) NCM(NC diet added 0.1% of herbal plant mixture) and 4) PCM(PC diet added 0.1% of herbal plant mixture). Through the entire experimental period, ADG of pigs fed NCM and PCM diets was greater(P<0.08) than that of pigs fed NC diet. There was interaction of ADG(P<0.01) in pigs fed NC diet with herbal plant mixture compared to pigs fed PC diet with herbal plant mixture. ADFI and G/F tended to increase in PC and NCM treatments. However, there were not significantly differences among the treatments. Total protein of serum was improved by supplementation of the herbal plant mixture in NC diet(P<0.04). For the Exp 2. one hundred Duroc(Yorkshir(Landrace pigs(77.36$\pm$2.01kg average initial body weight) were used in a 28 day experiment. Dietary treatments included 1) NC(negative control; antibiotics-free diet), 2) PC(positive control; NC diet added 0.1% of chlortetracycline), 3) PM0.1(NC diet added 0.1% of herbal plant mixture) and 4) PM0.2(NC diet added 0.2% of herbal plant mixture). Through the entire experimental period, ADG tended to increase in PC treatment. However, there was not significantly difference among the treatments. Carcass weight in NC was higher than other treatments(P<0.06). Backfat thickness was higher in pigs fed PC than other treatments. However, there was not significantly difference among the treatments. A grade appearances of carcass tended to increase in pigs fed PM(P<0.09). In conclusion, the results of the experiments suggest that pigs fed PM could be a beneficial growth performance and serogical immunity for finishing pigs.
