The current research aimed to evaluate the effects of dietary inclusion of wood vinegar on growth performance, nutrient digestibility, and meat quality of grower-finisher pigs. In total, 132 crossbred ({Landrace × Yorkshire × Duroc}) grower-finisher pigs with an initial average body weight 30.48±4.23 kg (11 replications/treatment; 4 pigs/pen) were used in a 16-week trial. Based on the body weight and sex the pigs were randomly assigned to three treatments. Dietary treatments consisted of the basal diet (CON) or the basal diet supplemented with 0.05% and 0.1% wood vinegar. The inclusion of dietary wood vinegar supplementation significantly improved the body weight gain (BWG) and average daily gain (ADG) (P=0.0521; 0.043) of pigs at week 16. The total track nutrient digestibility of dry matter and nitrogen was linearly increased in pigs fed with an increased amount of wood vinegar. In addition, dietary supplementation of wood vinegar linearly improved longissimus muscle area, yellowness (b*) of the meat color, and carcass weight (P<0.05) and a tendency in linear reduction was observed for water holding capacity (P=0.068), and drip loss at d5 and d7 (P=0.091, 0.069). However, there was no significant difference found for lean meat percentage and backfat thickness in this experiment. In summary, dietary inclusion of wood vinegar supplementation enhanced growth performance and total track digestibility of nutrients and had no effects on lean meat percentage and backfat thickness of grower-finisher pigs.
