Abstract

|

|
This study was conducted to investigate growth performance in weanling and growing pigs supplemented with mugwort powder as an antibiotic replacement. To examine the effects of antibiotic replacement, 0 (control, with and without antibiotics), 1, and 1.5% mugwort powder was supplemented into the basal diet. Pigs raised with a diet of 1.0% mugwort powder had improved average daily gain and feed conversion rate during 23~37 d feeding. During 40~59 and 63~97 d feeding periods, there were no differences between average daily gain in pigs fed no antibiotics and those given a 1% mugwort powder diet, whereas feed conversion rate of pigs given a 1.5% mugwort powder diet and average daily gain of pigs fed no antibiotics were lower than those of any other diet group. In conclusion, this study suggests that the 1.0% supplementation of mugwort in place of antibiotics is an invaluable feed additive as a physiologically activated material.
