Abstract: [Objectives] To study the effects of fermented nano Chinese herbal medicines replacing antibiotics on the production performance and carcass quality of growing-finishing pigs. [Methods] 200 healthy and disease-free Duroc-Landrace-Yorkshire (DLY) growing-finishing pigs with similar birth time (45 ± 2 d) and body weight of about 31.5 kg were randomly divided into group A (fed with non-antibiotic basal diet), group B (fed with antibiotic basal diet), group C (fed with non-antibiotic basal diet + 0.1% fermented nano Chinese herbal medicine preparation), group D (fed with non-antibiotic basal diet + 0.3% fermented nano Chinese herbal medicine preparation) and group E (fed with non-antibiotic basal diet + 0.5% fermented nano Chinese herbal medicine preparation). The experiment lasted for 90 d. At the end of the experiment, the production performance and carcass indicators were measured. [Results] Compared with group A, the final weight, average daily gain (ADG) and average daily feed intake (ADFI) of groups B, C, D and E were extremely significantly increased (P＜ 0.01), while the feed-to-gain ratio (F/G) was extremely significantly decreased (P＜ 0.01). Compared with group B, the ADG of group E was significantly increased (P＜0.05), while the F/G was significantly decreased (P＜ 0.05). Compared with group A, the slaughter rate and carcass length of pigs in groups B, C, D and E were extremely significantly increased (P＜0.01); compared with group B, the slaughter rate of groups D and E was extremely significantly increased (P＜0.01). [Conclusions] The fermented nano Chinese herbal medicine preparation has better effects in promoting growth are better than that of antibiotic additives, and it can significantly improve the carcass quality of growing-finishing pigs.
