Abstract Due to increased use of dried distillers grains with solubles (DDGS) in animal feed and accessibility of ethanol plants in the Midwest, this study evaluated the effect of feeding DDGS in place of soybean meal (SBM) on the fecal microbiome of Boer goats. Twenty-four Boer goat kids (apx. 70 d of age; 28.21 ± 0.96 kg) were blocked by BW and randomly assigned to 1 of 2 treatment diets for 47 d. Treatments were 0% (0DDGS) and 100% (30DDGS) DDGS in place of SBM. Goats were placed in 8 pens (4 pens/treatment; 3 goats/pen) with ad libitum access to feed and water. Fecal pellets were collected on d 47 via rectal grab and stored at -80°C until microbiome sequencing was performed. The V4 region of the 16S rRNA gene was sequenced by MR DNA (MR DNA, Shallowater, TX) on the Illumina HiSeq 2500 platform (Illumina, Inc., San Diego, CA). Data were analyzed using ANOVA with Tukey’s test for pairwise comparisons. Genera impacted by DDGS inclusion with individual relative abundances greater than 1% included increased Ruminococcus (P = 0.01) and Methanobrevibacter (P = 0.009) and decreased Lachnoclostridium (P = 0.02). Ruminococcus and Methanobrevibacter most likely increased in 30DDGS due to greater amounts of soluble fiber passing through the rumen, thus being fermented in the hindgut. The overall percentage of the phyla Bacteroidetes (P = 0.36) and Firmicutes (P = 0.12) did not differ between treatments; however, Firmicutes:Bacteroidetes increased (P = 0.05) in the 30DDGS diet. Treatment did not impact β-diversity (P = 0.47) although species richness increased (P = 0.09) in DDGS-fed goats as more soluble fiber was available for fermentation in the hindgut. In all, results of this study found replacing SBM with DDGS did not greatly alter the fecal microbiome of Boer goats.

The Impact

Abstract Due to the rising goat population in the United States, there is growing economic incentive to feed dried distillers grains with solubles (DDGS) over soybean meal (SBM). However, there is limited knowledge of how this may affect carcass composition. Therefore, the objective of this experiment was to evaluate the impact of titrating levels of DDGS as a replacement of SBM on Boer goat fatty acid profiles. Thirty-two Boer goat kids were fed isocaloric and isonitrogenous diets consisting of 0%, 33%, 66%, and 100% DDGS replacing SBM. There were no detected differences (P > 0.05) in final body weight after a 47-d growth experiment. Goats were slaughtered in a commercial, USDA-inspected facility, backfat samples collected between the 12th and 13th rib, and samples analyzed for fatty acid profile via AOAC Official Method 996.06. Data were analyzed with goat as the experimental unit in a completely randomized design. Dietary treatment did not impact (P > 0.05) the overall fatty acid profile or iodine value (50 to 52 points) of fat samples. This may be because fatty acids go through biohydrogenation by rumen bacteria, limiting the impact of diet on fatty acid profile. That said, increasing levels of DDGS impacted (P = 0.03) both C16:1 and C18:3 in a quadratic manner. Specifically, goats fed 0% and 100% DDGS replacing SBM had higher C16:1 than those fed intermediate levels of DDGS, while the opposite was true for C18:3. No other fatty acid was affected (P > 0.05), nor were there shifts in the ratio of saturated vs. unsaturated, or the total sum of n-3 fatty acids. In summary, fatty acid profiles are not significantly impacted by increasing levels of DDGS in place of SBM, and therefore DDGS can be used in Boer goat diets without impacting fat quality.

Dietary Treatments

Abstract We hypothesized that digestibility of a zinc polysaccharide complex (PSZn) is greater than zinc sulfate when sows consume high fiber diets containing dried distillers grains with solubles (DDGS). Gilts and sows (n = 32) were blocked according to parity and randomly assigned to one of four dietary treatments. Treatments were: 1) Control (ConZnSO4) – corn-soybean meal based diet + 100 ppm Zn from ZnSO4; 2) Control PSZn (ConPSZn) – corn-soybean meal based diet + 100 ppm Zn from PSZn; 3) DDGS/ZnSO4 – corn-soybean meal-40% DDGS gestation and 30% DDGS lactation diet, each containing 100 ppm Zn from ZnSO4; 4) DDGS/PSZn – corn-soybean meal-40% DDGS gestation and 30% DDGS lactation diet, each containing 100 ppm Zn from PSZn. Titanium dioxide was used as an indigestible marker to evaluate digestibility of nutrients and Zn. Quantitative urine collection was used to calculate retention of Zn in the four dietary treatments. The statistical model included fixed effects of diet, Zn source, and their interaction, and random effects of parity. Endogenous losses of Zn were estimated in sows fed a corn-soybean meal diet without added Zn. There were no differences in Zn concentrations of urine, plasma, colostrum, or milk samples among treatments at any time of the experiment (P > 0.05; data not shown). Gestating sows fed DDGS/PSZn had improved (P < 0.05) ATTD, TTTD, and overall retention of Zn compared to Control treatments (Table 1). Lactating sows consuming diets without DDGS and supplemented PSZn had the greatest (P < 0.05) ATTD, TTTD, and retention of Zn, which were opposite to responses observed in gestation. Furthermore, ATTD, TTTD, and Zn retention for lactating sows consuming DDGS/PSZn were less (P < 0.05) than all other treatments. Zinc digestibility of ZnSO4 and PSZn appears to be differentially influenced by stage of the reproductive cycle and presence of dietary fiber from DDGS.

Abstract. Contemporarily, the production of high-grade ethyl alcohol enables obtaining dried distillers decoction that contains post-fermentation residues of cereal grains, solubles as well as yeast cells and their metabolites multiplied in the fermentation process, which makes that product applicable also in poultry feeding. Experiments were conducted on 540 broiler chickens of COBB 500 line. One-day chicks were randomly allocated to 3 nutritional groups: K, D1 and D2, each group consisted of 6 replicates of 30 birds. The factor that differentiated the groups was the content of dried wheat decoction in the starter type feed mixture (5% and 7%). Production results (individual body weight, feed intake and mortality) of the birds were controlled in a 42-day rearing period. On the 42nd day of rearing, 6 male and 6 female chickens from each group were chosen for slaughter that had body weights similar to the average of each group according to gender. The aim of this study was to determine experimentally whether the by-product of ethanol production is suitable for replacing soybean meal in feeding broiler chickens. The application of the wheat decoction had no negative effect on production results of the chickens. The birds fed a mixture with a higher content of dried distillers grains with solubles (DDGS) were characterised by a similar body weight and better feed conversion ratio compared to the control birds. A properly-balanced (fibre, energy, amino acids) nutritional dose of the dried wheat decoction may be used as a good energy-protein component in feed mixtures for broilers. It is a rational means of DDGS management which is, simultaneously, a cheaper substitute for soybean meal.
