啤酒治疗牛消化障碍病

笔者曾试用啤酒治疗牛消化障碍而出现的不食、不反刍症，其效果不亚于药物治疗，且元任何副作用，现报告如下：     

喝啤酒也要讲科学

河北省营养学会秘书长马玉霞指出，夏天到了，许多朋友爱喝凉啤酒解暑，但喝啤酒也要讲科学，如果饮用不当，会对人的健康造成一定的危害。与薰制食品同食易致癌     

深井曝气+MBR工艺处理啤酒废水的试验研究

通过深井曝气+膜生物反应器(MBR)组合工艺对啤酒废水的处理试验和传统的处理啤酒废水处理工艺进行对比,结果表明:该处理工艺对啤酒废水的去除效果高于传统工艺,且产生的污泥量少,运行稳定,建造成本及占地面积都大大节省,具有推广价值.     

鲜啤酒糟饲喂妊娠母猪效果试验

用１７头１～２胎的迪卡Ｄ系妊娠母猪进行鲜啤酒糟的饲喂试验。试验分为２６％的鲜啤酒糟组（折干比例为８％）、４３％组（折干比例为１６％）及对照组。结果表明，试验各组无小产、早产、难产发生，两组平均产活仔均为１０．５头，高于对照组，也不低于同期大群产活仔数；产仔中无畸形胎；平均产死胎、木乃伊数低于对照组。试验９０天分别节约饲料成本２１元／头和４２元／头，经济效益明显。     

啤酒麦糟纤维素酶水解的研究

以经过适当预处理后的啤酒麦糟作原料，采用里氏木霉产生的纤维素酶进行水解．其纤维素的水解反应可描述为：①前６小时内迅速水解；②６～２４小时内较慢水解；③２４小时后缓慢水解．在水解过程中，存在纤维二糖的积累．且以前６小时积累较多，纤维二糖的最高浓度可达７．５２ｇ／Ｌ．水解前期采取分批添料方法，可提高水解得率和底物浓度．并大大提高水解液中还原糖的浓度．     

Effect of Soybean Meal Replaced by Brewer's Grain or Fermented Brewer's Grain on Growth Performance,Immune Organ Index and Intestinal Flora of Meat Geese

This experiment was conducted to investigate the effect of soybean meal replaced by brewer's grain (BSG) or fermented brewer's grain (FBSG) on growth performance,immune organ index and intestinal flora of meat geese.A total of 250 geese at 28 days of age were randomly assigned to 5 groups with 5 replicates per group and 10 geese per replicate.The geese in control group were fed a basal diet (with soybean);The geese in groups 1 and 2 were fed the basal diet with the 10% and 20% BSG replacing the soybean,respectively;The geese in groups 3 and 4 were fed the basal diet with the 10% and 20% FBSG replacing the soybean,respectively.The whole experiment period was 42 days,including three phases:15 d (early stage),14 d (middle stage) and 14 d (later stage).The results showed as follows:①From the whole experiment period,compared with control group,the ADG of geese in group 1 was significantly increased (P<0.05),the ADG and ADFI of geese in group 4 were significantly decreased (P<0.05),there were no obvious change in growth performance of geese in groups 2 and 3 (P>0.05).② Compared with control group,the thymus index and spleen index of geese in groups 1,2 and 3 were extremely significantly increased at early stage (P<0.01);At middle and later stages,the spleen index of geese in group 2 were significantly and extremely significantly increased (P<0.05;P<0.01);There were no significant differences in bursa of fabricius index of geese among all groups (P>0.05).③ Compared with control group,the number of Escherichia coli and Salmonella in cecum in groups 1 and 2 were extremely significantly decreased at early and later stages (P<0.01),while the number of Bifidobacteria and Lactobacillus were increased in different degrees;the number of Bifidobacteria and Lactobacillus in cecum in groups 3 and 4 were extremely significantly increased at later stage (P<0.01).In conclusion,10% BSG replacing soybean in the basal diet could improve the growth performance and intestinal flora of meat geese;10% FBSG replacing soybean in the basal diet could promote the growth of beneficial bacteria of meat geese,but had no effect on growth performance;While 20% replacing soybean in the basal diet could decrease the feed intake and weight gain of meat geese,hinder its growth and development.

啤酒废水培养螺旋藻的研究

[目的]研究啤酒废水培养螺旋藻的可行性。[方法]利用啤酒废水培养螺旋藻,研究不同废水浓度下螺旋藻的生长状况及其对废水中氮、磷、有机质的去除效率,以及在放大培养时螺旋藻的生物量、蛋白质和脂肪含量。[结果]螺旋藻可在啤酒废水中生存,且啤酒废水有缓冲培养液pH增加的作用,能使螺旋藻更长时间处于适宜生存的状态。50%啤酒废水、50%Zarrouk培养液最适宜螺旋藻生长,且产量达到最大。同时,螺旋藻可对啤酒废水产生净化作用。螺旋藻对100%啤酒废水中有机质、总氮、总磷的去除效率分别可达55.95%、77.78%和42.62%。在最佳配比浓度条件下,放大培养的产藻量为0.794 g/L,蛋白质和脂肪含量分别达到69.5%和8.11%。[结论]该研究可使污水净化和螺旋藻利用相结合,达到环境与经济效益的统一。     

以还原糖含量为指标的膨化小麦辅料麦汁糖化工艺优化

以水料比、膨化小麦比例、50℃蛋白质休止时间、62℃糖化时间、70℃糖化时间为糖化工艺参数,以还原糖含量为主要考察指标,通过对挤压蒸煮小麦辅料酿造啤酒的糖化工艺进行响应面法优化,得到最佳的糖化工艺参数:水料比为3.7 m L∶1 g,膨化小麦比例为32%,50℃蛋白质休止时间为53 min,62℃糖化时间为47 min,70℃糖化时间为31 min。此时,对应的麦汁还原糖含量为86.1 mg/m L。
