摘要
为研究酒精糟及残液干燥物(DDGS)营养价值(与豆粕比较),测定了DDGS常规养分,结果表明DDGS的粗蛋白、粗脂肪、粗纤维、CaP2,P含量分别为40.00%、8.60%、7.45%、0.10%和0.60%。其中粗纤维和粗脂肪含量高于豆粕,其余养分含量与豆粕相当。并选用12只成年蛋用公鸡,采用随机区组设计测定了DDGS和豆粕中粗蛋白表观代谢率和表观代谢能,结果表明二者差异不显著(P>0.05),表明DDGS对蛋鸡有较高的营养价值。
Two experiments were conducted to study the nutritional value of DDGS （Distillers Drier Grains plus Solubles） . Experiment I , the conventional nutrients were determined. The result indicated that the CP, EE ,CF, Ca, P in the sample used were 40.00%, 8.60%, 7.45%, 0.10%, 0.60%, respectively. CF and EE in DDGS were higher than soybean meal, while other conventional nutrients were of the same level. Experiment Ⅱ, randomized block design was adopted, 12 cocks were choosed to determine the AME （apparent metabolizable energy） , AMR （apparent metabolic rate） of CP in DDGS and soybean meal by using the difference method. The result showed that the difference were not significantly （P〉0.05） . The result indicated the DDGS has higher nutritive value to the laying hen.
