Dried distillers grains with solubles (DDGS) contain large quantities of nutrients including energy, crude protein (CP) and non-phytate phosphorus. Nevertheless, DDGS includes high amounts of fibre mainly consisting of non-starch polysaccharides (NSP), which normally acts as an anti-nutritive factor in the digestion of monogastric animals. In this context, a study was conducted to determine the applicability to use DDGS as main protein source with and without NSP-hydrolyzing enzymes in diets of pigs for fattening. Additional parameters for intestinal microbial activity should be evaluated to improve the understanding of the physiological mode of action of DDGS in the gut. A total of 60 male crossbred pigs were fed four experimental diets, arranged in a 2×2 factorial approach with factor DDGS and factor NSP-hydrolysing enzymes. All diets were formulated to contain similar concentrations of ME, standardized ileal digestible (SID) Lys, SID Met, SID Thr and SID Trp. During slaughter procedure digesta of three parts of the intestine (ileum, colon, rectum) and blood were collected for analysis of dry matter, ammonia and short chain fatty acids. Zootechnical performance parameters as well as carcass characteristics were not affected by the experimental factors DDGS or NSP-hydrolyzing enzymes. However, DDGS increased colonic DM content (+6.5%; p<0.05), significantly decreased the sum of SCFA in colon digesta DM about 18.5% and enhanced urea content in blood plasma (p<0.05). Enzyme supplementation showed no effects on DM and volatile fatty acid contents in the gut and enhanced NH3 concentration in digesta of ileum and colon. The present study indicates that grower-finisher pigs tolerate DDGS as sole protein source in their diets, without impairing important zootechnical and carcass parameters.
