These experiments investigated the suitable level of charcoal powder-wood vinegar compound in post weaned pig diets. Thirty-two pigs (16 females and 16 castrated males, 5 weeks of age) were randomly assigned to 4 treatments: 0, 1, 3 and 5 percent of charcoal powder-wood vinegar compound (CWVC) in the experimental diets respectively based on randomized complete block design. The animals were kept individually where feed and water were provided ad libitum. The results showed no statistically significant among 4 groups on total weight gain, average daily gain, daily feed intake feed conversion ratio and feces score (P GT 0.05). However, hard feces were slightly increased as the level of CWVC diets. The intestinal villi of pigs those fed by 1 and 3 percent dietary CWVC were higher (P LT 0.01) than the other. The result of total plate count and coliform in feces and colon of pigs fed 0, 1, 3 and 5 percent dietary CWVC were no statistically significant (P GT 0.05). The lactic acid bacteria in colon of pigs those fed 1 and 3 percent dietary CWVC were higher than the other 2 groups (P LT 0.05). However, the microorganisms in feces of all groups were no statistically significant. Thus, the suitable level of CWVC in diets is 1 - 3 percent, by which could induce the healthy in pig. Furthermore, these could be an alternative in organic swine production.
