This study was conducted to determine the effect of dietary red ginseng on growth performance, nutrient digestibility, blood profile, meat quality, and carcass grade in growing-finishing pigs. A total of 120 crossbred pigs ([Landrace x Yorkshire] x Duroc) with an average body weight of 21.77 ± 1.88 kg were used in 22 wk experimental period. Pigs were randomly assigned to 3 treatments with 8 replications (5 pigs per replication). Dietary treatments included: 1) CON, basal diet; 2) TRT1, CON + 0.1% fermented red ginseng; 3) TRT2, CON + 0.2% fermented red ginseng. All data were analyzed as a randomized complete block design using mixed procedures of SAS. In the current study, no significant difference was observed on average daily gain (ADG), average daily feed intake (ADFI), and gain to feed ratio (G/F) among treatments at 10th, 18th and 22th weeks. However, pigs fed with TRT1 diet (657 g) had higher ADG (P < 0.05) than those fed with CON diet (634 g) at sixth week. Overall, a significant increase (P < 0.05) in ADG was observed in TRT1 treatment (550 g) compared with CON treatment (542 g), and no effect was observed on ADFI, FCR, and G/F. Apparent total tract digestibility (ATTD) of dry matter (DM) in TRT1 treatment (81.46) was higher (P < 0.05) than that of CON treatment (78.03). In addition, ATTD of nitrogen (N) in pigs fed with TRT1 diet (81.89) was higher (P < 0.05) compared with pigs fed with CON diet (76.08) and TRT2 diet (77.37). No significant difference was observed in the ATTD of energy (E) among treatments at sixth and 10th weeks. Supplementation of red ginseng in TRT1 treatment significantly decreased (P < 0.05) drip loss at d 1 (1.38), d 5 (4.60) and d 7 (7.01) post slaughter. On d 9, drip loss of CON treatment (13.92) was considerably lower than TRT1 treatment (8.68) and TRT2 treatment (11.12). Meantime, drip loss of TRT2 treatment (11.12) was significantly higher than TRT1 treatment (8.68). In conclusion, results of the present study indicated that supplementation of red ginseng enhanced growth performance, nutrient digestibility and decreased meat drip loss, with no significant effect on blood profile and carcass grade in finishing pigs.
