Due to increased use of dried distillers grains with solubles (DDGS) in animal feed and accessibility of ethanol plants in the Midwest, the effect of feeding DDGS in place of soybean meal (SBM) on growth, economics, carcass characteristics, backfat fatty acid profiles, and fecal microbiome of Boer-cross goats was evaluated. Forty-eight Boer-cross goats (approximately 70 d of age; 28.21 ± 0.96 kg) were blocked by BW and assigned to 1 of 4 dietary treatments in a completely randomized design. Treatments were 0 %, 33 %, 66 %, or 100 % DDGS replacing SBM, equating to the inclusion of 0 % (0DDGS), 10.3 % (10DDGS), 20.5 % (20DDGS), or 31.1 % (30DDGS) DDGS in the total diet. The inclusion rates of corn and soybean hulls were adjusted to maintain isocaloric and isonitrogenous diets. Goats were provided ad libitum access to feed and water for 47 d. There were 3 goats/pen and 4 pens/treatment. The inclusion of DDGS linearly improved (P = 0.01) average daily gain (ADG) and gain:feed (G:F; P = 0.001), without affecting average daily feed intake (ADFI; P > 0.10) in goats fed DDGS in place of SBM. Feed cost/kg gain decreased (P < 0.0001) with increased inclusion of DDGS, which led to a linear increase in value of gain (P = 0.02) with increased DDGS inclusion. Bacterial and archaeal genera with individual relative abundances greater than 1% in feces that were impacted by 30DDGS were increased Ruminococcus and Methanobrevibacter (P < 0.01) and decreased Lachnoclostridium (P = 0.02). Ruminococcus and Methanobrevibacter most likely increased in goats fed 30DDGS due to greater amounts of soluble fiber passing through the rumen, thus being fermented in the hindgut. While there were no differences detected in overall percentage of phyla Bacteroidetes (P = 0.36) and Firmicutes (P = 0.12) among treatments; the Firmicutes:Bacteroidetes was greater (P = 0.05) in goats fed 30DDGS than those fed 0DDGS. There was no observed impact (P = 0.47) of treatment on β-diversity, although Shannon Index tended to increase (P = 0.09) in goats fed 30DDGS possibly because more soluble fiber was available for fermentation in the hindgut. Polyunsaturated fatty acids over the 12th rib tended to increase quadratically (P = 0.06) with increased DDGS inclusion, yet there was no differences observed in the saturated fatty acid to unsaturated fatty acid ratio (P = 0.93) or iodine value (P = 0.36) with increased levels of DDGS. Up to 100 % of the SBM in a Boer-cross finishing goat ration can be replaced by corn DDGS with no detectable difference in growth performance, fecal microbial populations, carcass characteristics, or fatty acid profile.

由于在中西部动物饲料中增加了使用干溶物酒糟（DDGS）的使用以及中西部乙醇工厂的可及性，用DDGS代替豆粕（SBM）进料对生长，经济，car体特性，背脂脂肪酸谱的影响，并评估了波尔杂交山羊的粪便微生物组。BW阻断了48只Boer杂交山羊（约70 d； 28.21±0.96 kg），并以完全随机设计分配给4种饮食疗法中的1种。处理是用0％，33％，66％或100％的DDGS代替SBM，等于在DDGS中包含0％（0DDGS），10.3％（10DDGS），20.5％（20DDGS）或31.1％（30DDGS）DDGS。总饮食。调整玉米和大豆皮的包含率以维持等热量和等氮饮食。为山羊提供了47天的自由采食和饮水的条件。有3只山羊/笔和4只笔/处理。包含DDGS的线性改进（P = 0.01）平均日增重（ADG）和增益：饲料（G：F; P = 0.001），但不影响以DDGS代替SBM饲喂的山羊的平均日采食量（ADFI; P > 0.10）。DDGS含量增加，饲料成本/公斤增重降低（P <0.0001），DDGS含量增加，导致增重值线性增加（P = 0.02）。与受影响30DDGS粪便中个别相对丰度大于1％细菌和古细菌属分别提高瘤胃球菌和甲烷短（P <0.01）和降低的Lachnoclostridium（P = 0.02）。瘤球菌和在饲喂30DDGS的山羊中，甲烷短杆菌很可能会增加，因为大量可溶性纤维通过瘤胃，从而在后肠中发酵。虽然在各处理之间未发现细菌类杆菌的总百分率（P = 0.36）和硬菌纲（P = 0.12），但差异无统计学意义。饲喂30DDGS的山羊比饲喂0DDGS的山羊的拟杆菌（P = 0.05）更大。尽管香农指数趋于增加（P = 0.47），但治疗对β-多样性没有影响（P = 0.47）。= 0.09）在饲喂30DDGS的山羊中，可能是因为更多的可溶性纤维可用于后肠发酵。随着DDGS含量的增加，第12条肋骨上的多不饱和脂肪酸呈二次增加趋势（P = 0.06），但在饱和脂肪酸与不饱和脂肪酸之比（P = 0.93）或碘值（P = 0.36）上没有观察到差异。DDGS水平升高。在布尔杂交山羊配比中，高达100％的SBM可以被玉米DDGS取代，但在生长性能，粪便微生物种群，car体特征或脂肪酸谱方面没有可检测到的差异。
