Jessada (2014) added combined product of bamboo charcoal
powder and bamboo vinegar at dosages of 0, 0.5%, 1% and 1.5% to
the feed of Betong chickens and found that 1% group showed
optimum growth performance. This researcher proposed that
combined product of bamboo charcoal powder and bamboo vinegar
could be applied in Betong chicken production to enhance
growth. Choi et al. (2009) reported that ADG and feed conversion
ratio of pigs fed 0.2% wood vinegar were evidently improved
compared with control group and the improvement was only second to antibiotics group. Moreover, wood vinegar experimental
group showed optimum ADFI. In our study, growth performances of
weaned piglets in bamboo vinegar powder experimental groups
were evidently improved, with no significant difference from antibiotics
group. This manifested that bamboo vinegar powder
showed growth-enhancing effects on weaned piglets, which could
match antibiotics. Especially, F:G of BV5 was significantly lower
than that of CON, indicating that 0.5% might be the proper dosage.
