“…In our study, DDGS addition reduced (P<0.05) fecal pH, indicating a possible prebiotic effect. Silva et al (2016) also observed a pH reduction by incorporating 180 g kg −1 DDGS into diets for dogs and attributed this to an increase in total SCFA production (Kawauchi et al, 2011). Likewise, Lopez et al (1999) evaluated diets for rats containing AX (one of the main NSP of DDGS) and observed a reduction in fecal pH from 7.0 to 6.0; they assigned this effect to SCFA accumulation in animal intestines, as observed in our study.…”

“…Reductions in the ADC of DM, OM, EEAH, CP, GE, and ME caused by DDGS addition have also been reported by Silva et al (2016), who evaluated dogs fed increasing DDGS levels (0, 60, 120, and 180 g kg −1 ). These authors correlated the declines with increasing NSP in the diets.…”

“…The addition of enzymes had no effect on nutrient digestibility or ME of the diets, unlike the findings in the literature on dogs. For instance, Silva et al (2016) tested increasing DDGS levels and xylanase supplementation and observed increases in the ADC of CP, DM, and OM when the enzyme was added; they also noted that the ADC of CP was similar between treatments with and without the inclusion of the ingredient (Silva et al, 2016). Such a difference in results could be due to the enzyme concentration, as in our study, the concentration was lower (0.2 g kg −1 ) than that used by Silva et al (2016) (0.5 g kg −1 ).…”

“…The main NSP in DDGS are insoluble fibers, which tend to hasten the passage of food through the gastrointestinal tract, decreasing nutrient digestibility. Besides, part of the protein in DDGS is associated with fiber, which impairs its digestibility in monogastric animals (Nuez Ortín and Yu, 2009;Chrenková et al, 2012;Silva et al, 2016).…”

“…Reports in the literature have shown that replacing corn with up to 180 g kg −1 DDGS formulation in diets for dogs may be feasible if associated with xylanase supplementation (Silva et al, 2016). However, higher concentrations of this ingredient associated with other enzymes have not yet been tested in canine diets.…”

Effects of adding dried distillers grains with solubles (DDGS) to dog diets supplemented with xylanase and protease

This study aimed to evaluate the effects of including 200 g kg −1 dried distillers grains with solubles (DDGS) to xylanase-and protease-supplemented diets for dogs on kibble properties, digestibility, fecal characteristics, and palatability. Experimental diets consisted of: 0 g kg −1 DDGS without enzymes (0WE), 0 g kg −1 DDGS with xylanase and protease (0XP), 200 g kg −1 DDGS without enzymes (200WE), 200 g kg −1 DDGS with xylanase (200X), 200 g kg −1 DDGS with protease (200P), and 200 g kg −1 DDGS with xylanase and protease (200XP). Kibbles were evaluated for density, extruded size, expansion index, hardness, and uniformity. Six beagle dogs were distributed in a 6×6 Latin square design for analysis of digestibility and fecal characteristics. A palatability assay was also conducted in 16 beagle dogs, comparing the following treatment groups: 0WE vs. 200WE and 0XP vs. 200XP. The results showed that DDGS inclusion had no influence on kibble physical properties and reduced digestibility of dry matter (DM), ether extract after acid hydrolysis, gross energy, and organic matter, regardless of enzyme addition. Moreover, dietary addition of DDGS reduced fecal pH and increased total short-chain fatty acid, acetate, and propionate productions. Fecal odor was increased in dogs fed diets containing DDGS. Regarding palatability, animals preferred diets supplemented with enzymes and without DDGS, and no difference was observed when comparing 0WE and 200WE diets. No changes in the physical properties of kibbles were caused by DDGS inclusion; therefore, it can be used in diet formulation without interfering with the industrial process. Increased production of SCFA and a possible modulation of digestive tract microbiota promoted by DDGS addition may benefit animals. However, at the tested levels, enzymes had no positive effects on diet digestibility. Despite reducing digestibility, DDGS can still be included without enzyme supplementation in low-cost diets for dogs, as nutrient digestibility of the diet remains within acceptable limits for some pet food categories.
