Dietary Soybean Oligosaccharides Addition Increases Growth Performance and Reduces Lipid Deposition by Altering Fecal Short-Chain Fatty Acids Composition in Growing Pigs

Abstract

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 p p p < 0.05). In summary, 0.8% SBOS supplementation to growing–finishing pigs’ diets can reduce lipid deposition and increase ADG.
