Ninety six crossbred pigs (Landrace×Yorkshire×Duroc) were used to determine the effects of essential oils (Fresta F Conc ® ) supplementation on growth performance, immune response and fecal noxious gas of weaned pigs. Treatments were 1) NC (negative control; basal diet without antibiotics), 2) PC (positive control; basal diet+CSP (CTC+Sulfathiazole+Penicillin) 0.1%), 3) NCF (basal diet+Fresta F Conc ® 0.03%) and 4) PCF (basal diet+CSP (CTC+Sulfathiazole+Penicillin) 0.1%+Fresta F Conc ® 0.02%). From d 0 to 14, ADFI was increased in pigs fed PCF diet (p 0.05). No statistical differences (p>0.05) were found in red blood cells (RBC) counts, white blood cells (WBC) counts, lymphocyte counts, total protein and albumin. Serum IgG concentration of PCF treatment was greater than that of other treatments (p 0.05). From d 14 to 28, digestibility of dry matter in pigs fed PC, NCF and PCF diets was higher than that of pigs fed NC diet (p 0.05) were found in volatile fatty acid (VFA), ammonia nitrogen (NH3-N) and hydrogen sulfide (H2S) concentrations among treatments. On d 49, there was no significant difference in VFA concentration among the treatments (p>0.05). NH3-N concentration in pigs fed PCF diet was lower than in pigs fed other diets (p<0.05). H2S concentration in pigs fed diets with added essential oils was lower than others. In conclusion, the results suggest that the dietary addition of essential oils and antibiotics into diets for weanling pigs improved growth performance, IgG concentration and nitrogen digestibility and decreased noxious gas concentration. Essential oils can be used to partly replace antibiotics in diets for weaned pigs without negative affects on growth performance. (Asian-Aust. J. Anim. Sci. 2006. Vol 19, No. 1 : 80-85)
