In this study, adding 0.4% bamboo vinegar in feed was effective in improving the performance of piglets, and comparable with the pigs fed diets containing antibiotics. Due to the higher feed intake of pigs in BV4 and antibiotics, the final weight and daily weight gain for pigs in both treatments were significantly higher than those in control, therefore feed to gain ratio was not significantly different among treatments. The physical condition was good for animals on bamboo vinegar, similar to animals treated with antibiotics during the whole experiment. The results manifested that the bamboo vinegar has the potential to replace antibiotics.
