Popis: One hundred and twenty-eight boars and gilts of the Duroc × Landrace × Yorkshire variety with an initial body weight (BW) of 52.49 ± 0.48 kg were used in a randomized complete block design for a 63-day experiment. The four treatment groups were: control diet (CON), CON + 0.2% soybean oligosaccharides (SBOS), CON + 0.4% SBOS, and CON + 0.8% SBOS. The results showed that the average daily weight gain (ADG) was significantly higher in the 0.8% SBOS group than in the CON group on days 0–63 (p < 0.05). Compared with the CON group, adding 0.8% SBOS to the diet significantly increased the carcass weight, dressing percentage, and carcass lean percentage, but decreased the average backfat depth of growing–finishing pigs (p < 0.05). Adding different concentrations (0.2%, 0.4%, and 0.8%) of SBOS to the diet can significantly increase the concentrations of acetate, propionate, and butyrate in feces (p < 0.05). The activities of malic enzyme and fatty acid synthase in the 0.8% group were significantly lower than those in the 0.2% and CON groups (p < 0.05). In summary, 0.8% SBOS supplementation to growing–finishing pigs’ diets can reduce lipid deposition and increase ADG.
