The physical characteristics, chemical composition, and nutritional value of distillers dried grains with solubles (DDGS) from seven beverage alcohol and two fuel alcohol manufacturers were evaluated in studies with chicks and pigs. Color scores of the DDGS ranged from very light to very dark and odor scores ranged from normal to burnt or smoky. The DDGS ranged from 23.4 to 28.7% CP, 2.9 to 12.8% fat, 8.8 to 36.9% ADIN, 28.8 to 40.3% NDF, 10.3 to 18.1% ADF, and 3.4 to 7.3% ash. Lysine concentrations of the DDGS ranged from .43 to .89%. In the first experiment, 12 corn-based diets were fed to 1-d-old chicks for 21 d to assess the nutritional value of the DDGS sources. A low-protein basal diet was supplemented with soybean meal to provide 13.6, 16.5, or 19.0% CP or supplemented with 20% DDGS, which supplied approximately the same amount of CP as the highest level of soybean meal. Weight gain, feed intake, and feed/gain were influenced (P < .01) by source of DDGS. The weight gain of chicks fed the DDGS sources ranged from 85% of that chicks fed the highest level of soybean meal to less than that of chicks fed the low-protein basal diet. Blends of the three best sources of DDGS and the three poorest sources of DDGS were evaluated in a subsequent chick trial. The relative nutritional values of the two blends were similar to the average of the sources that made up the blends. Performance responses to various blends of DDGS in the pig experiment paralleled those of the chick trial.(ABSTRACT TRUNCATED AT 250 WORDS)
在针对雏鸡和仔猪的研究中，对来自7家饮料酒精生产商和2家燃料酒精生产商的可溶物干酒糟（DDGS）的物理特性、化学成分和营养价值进行了评估。DDGS的颜色评分从非常浅到非常深，气味评分从正常到烧焦或烟熏味。DDGS的粗蛋白含量在23.4%至28.7%之间，脂肪含量在2.9%至12.8%之间，酸性洗涤不溶氮含量在8.8%至36.9%之间，中性洗涤纤维含量在28.8%至40.3%之间，酸性洗涤纤维含量在10.3%至18.1%之间，灰分含量在3.4%至7.3%之间。DDGS的赖氨酸浓度在0.43%至0.89%之间。在第一个实验中，将12种以玉米为基础的日粮喂给1日龄的雏鸡，持续21天，以评估DDGS来源的营养价值。一种低蛋白基础日粮添加豆粕以提供13.6%、16.5%或19.0%的粗蛋白，或者添加20%的DDGS，后者提供的粗蛋白量与最高水平的豆粕大致相同。DDGS来源对雏鸡的体重增加、采食量和料肉比有影响（P < 0.01）。饲喂DDGS来源的雏鸡体重增加量介于饲喂最高水平豆粕的雏鸡的85%到低于饲喂低蛋白基础日粮的雏鸡之间。在随后的雏鸡试验中，评估了三种最佳DDGS来源和三种最差DDGS来源的混合日粮。两种混合日粮的相对营养价值与组成混合日粮的来源的平均值相似。在仔猪实验中，对不同DDGS混合日粮的性能反应与雏鸡试验相似。（摘要截短至250字）
