利用稻谷粉代替麦麸栽培袋菇的试验

香菇是景宁县农业生产的主要支柱产业，2002年全县生产袋菇7000万袋。而麦麸是袋栽香菇的主要原材料，按照常规配料方法每千袋所需麦麸160kg计算，仅2002年景宁县就需麦麸11200多吨。以往景宁的麦麸大多从山东、江苏等地购入，因路途遥远。

用于乙醇脱水的生物质吸附性能

The adsorption capability of paddy flour and maize flour for gaseous phase selective adsorption for ethanol dehydration was investigated via a bench-test fixed-bed adsorber at constant temperature. Ethanol concentration in the feed was 93.4%(mass) and each of the dried biomass was used as adsorbent, and breakthrough curves and temperature distribution in adsorptive bed were obtained for different bed depths, superficial velocities, granularities of adsorbent and temperatures. Bed pressure drop curves for different bed depths and superficial velocities were also measured. A product of ethanol purity of 99.5%(mass) could be obtained through both kinds of biomass adsorbent. When 99.5%(mass) of ethanol purity is defined as the breakthrough point, the production capacity for either adsorbent was within 0.0915—0.2256 (gram product/gram adsorbent). Tests on pure ethanol adsorption were also performed to extrapolate the selectivity of both adsorbents.

早稻转化为肉势在必行

早稻转化为肉势在必行余欣荣江西是全国水稻主产省，粮食是江西的一大优势。在市场经济条件下，如何把粮食优势转化为畜牧优势，促进农业和农村经济的持续健康快速发展，是当前急需探讨和解决的问题。向早稻要肉，建畜牧大省，是稳定农业，稳定粮食生产，促进畜牧业发展，...

木薯代替玉米喂猪配方介绍

木薯含粗蛋质仅2.56％,比玉米的7.8％要低。但木薯是一种高能量饲料,据分析,每公斤木薯干品含消化能3180大卡.比稻谷高出15％,与玉米(3410大卡)差不多、并且木薯的价格要比玉米低。所以,利用木薯代替玉米喂猪有着广阔的前途 一。

肉鸭人工填饲快速育肥法

肉鸭人工填饲育肥法,比一般舍饲育肥法和放牧育肥法可缩短一半育肥时间。其技术要点是:一、科学配料:配方①:玉米粉50%、高梁糠或米糠20%、高梁粉或大麦粉15%、红苕干粉5%、豆饼8%,骨粉1.5%、食盐0.5%。配方2:玉米粉55%,稻谷粉20%,麦麸5%,大豆粉6.5%,蚌粉2%,骨粉1%。

滤泥在养殖业中的应用

滤泥是制塘工业的大宗副产品。经煮糖后所得到的沉淀物即为滤泥。滤泥是能部份或完全取代粮食的物美价廉的饲料。滤泥于物质含糖分16%左右,新鲜的滤泥具有香甜味,用作饲料适口性较好。滤泥的酸碱度接近中性。并含有铜、铁、锰、锌、硫等多种元素,铅和砷等有害元素的含量均在允许范围内。

秋季耕牛抓膘措施

做好秋季耕牛抓膘工作,对确保耕牛安全越冬至关重要。秋季膘情差的牛,入冬后常因天气寒冷和营养不良而更加消瘦,甚至死亡。1.加强放牧,让牛吃饱秋季正是青草抽穗开花或盛花季节,草料营养丰富,饲养价值高,但长势缓慢。因此,牧草丰盛的地区可采取早放晚归;牧草较缺乏的地区应全日放牧,白天让牛尽量吃饱,晚上加些夜草,使牛获得足够营养,促进长膘。2.老弱病牛,补充精料对体质差的老弱病牛、犊牛和带仔母牛,要补充精料,每头每天添喂玉米粉、稻谷粉、麦粉及糠麸等1.5～2公斤。对食欲欠佳的牛,可加喂茴香盐刺激其食欲。其配合量为茴香100克,食盐50克,加少量水熬制,饲喂时连同渣一起喂给。
