The distiller’s dried grain with soluble is a by-product from liquor production which contains multiple anti-nutritional properties but helps reduce the feed cost. However, the fermented sorghum distiller's dried grain with soluble (FS-DDGS) has an increased nutrient bioavailability and has shown benefits in the aminoacid metabolism, the intestinal microbiota, and the intestinal health of weaned piglets. Nevertheless, little is known on the beneficial effects of FS-DDGS on the growth performance and carcass traits of growing-finishing pigs.
Methods: The present study evaluated the effects of dietary FS-DDGS addition on growth performance, carcass traits, and meat quality in growing-finishing pigs. A total of 48 healthy male crossbred (Large White × Landrace × Duroc) barrows with initial body weight of 39.95 ± 2.15 kg were allocated to one of four dietary treatments (12 pigs per treatment). The dietary treatments were as follows: basal diet without or with 50 g/kg, 100 g/kg, or 150 g/kg FS-DDGS, respectively. After 90 days of trial, carcass traits, meat quality and its chemical composition were measured in all pigs.
Results: There were no significant differences in the final body weight, average daily gain, average daily feed intake, and feed to gain ratio among these four groups. However, dietary FS-DDGS addition increased (linear) the pH24h value, contents of ash, crude protein, and proline in Longissimus dorsi muscle, and alanine, arginine, aspartic acid, glutamic acid, isoleucine, leucine, lysine, serine, and tyrosine in Biceps femoris muscle, when compared with the control group. In addition, dietary FS-DDGS addition decreased (linear) the drip loss, yellowness (b*) value, and lightness (L*) value, while quadratically improving the total bone percentage and glycine and proline contents in Biceps femoris muscle compared with the control group.
Conclusion: Collectively, these findings suggested that dietary FS-DDGS addition could improve the carcass traits and meat quality in growing-finishing pigs.
