本试验旨在评定发酵白酒糟营养价值及其对育肥猪生长性能的影响.利用胃蛋白酶-胰酶二步法体外消化测定发酵白酒糟的营养价值,再进行育肥猪的饲养试验.采用单因子试验设计,选取体重52.57 kg左右的育肥猪28头,随机分配到4个处理组:对照组、Ⅰ组、Ⅱ组和Ⅲ组.每组7个重复,每个重复1头育肥猪,试验期为27 d.后三组用6％的发酵白酒糟代替部分玉米、麸皮、豆粕等日粮原料.结果表明:发酵白酒糟在40℃恒温体外消化装置下持续消化6 h至消化完全,此时干物质消化率为42.12％,蛋白质消化率为64.29％,粗纤维消化率为20.86％.用6％的发酵白酒糟代替以纤维类为主的饲料原料可提高育肥猪生长性能,增加经济效益.本...

This experiment was conducted to evaluate the nutritional value of fermented distiller's grains and its growth performance.The nutritional value of fermentation liquor was determined by digestion of pepsin-trypsin,finally proceeding the pig feeding experiment.A single-factor test design was used to select the fatten pig with weight of 52.57 kg and randomly assigned to 4 treatment groups:control group and theⅠ,Ⅱ,Ⅲgroup,each group had seven replicates,and each replicate with one pig.The experiment was lasted for 27 days.The last three groups u...
