The purpose of corn fermented feed is to promote the recycling of resources and develop circular economy. The special high-temperature fermentation technology is adopted to use the by-products of high-temperature complex bacteria food processing industry, such as corn, corn husk, flour, miscellaneous and other raw materials as microbial fermented food, as well as independent research and development and production of high-tech fermented corn feed materials.
We conducted an experiment to prove the optimization effect of fermented corn in feed:
采用常规饲料检测法测定饲料中的干物质、总能量、灰分、粗蛋白、钙、总磷和氯的含量，采用TCA法测定植酸磷的含量。我们选择来源是相同的,类似的重量(70公斤),健康状况良好的三元混合商业70头,随机分为两组,每个处理4个重复,每个重复8 ~ 9,男性女性一半,消化实验(内部指标法、4摩尔/ LHCl、酸不溶性灰分),可以测量其明显的消化和营养物质的表观消化率。结果表明:
The content of dry matter, total energy, ash, crude protein, calcium, total phosphorus and chlorine in feed were determined by routine feed detection method, and the content of phytate phosphorus was determined by TCA method. We selected 70 commercial ternary mixtures with the same source, similar weight (70kg) and good health. They were randomly divided into two groups. Each treatment had four repetitions, each of which was 8-9, half of which was male and half of which was female. The apparent digestibility of digestion and nutrients could be measured by digestion experiment (internal index method, 4 mol / lhcl, acid insoluble ash). The results show that:
The nutrient content (%) of corn dry fermentation feed were: dry matter 88.82, crude protein 12.84, calcium 0.675, total phosphorus 0.235 and non phytate phosphorus 0.235, respectively.
The apparent digestibility (%) of conventional nutrients in air dried fermented corn feed was 82.75 for dry matter, 81.02 for energy and 91.58 for crude protein, respectively.
滕州玉米干发酵饲料表观消化率为13.18 MJ/kg，总能量为16.24 MJ/kg。
The apparent digestibility of Tengzhou corn dry fermentation feed was 13.18 MJ / kg, and the total energy was 16.24 MJ / kg.
It can be seen that fermented corn feed has high digestibility and high absorption of energy, protein, calcium, available phosphorus and other nutrients.
发酵玉米可部分替代能量饲料原料，节省玉米、小麦、大米等能量饲料在畜牧业和水产养殖中的应用，复合饲料的添加量应在5% ~ 10%之间。
Fermented corn can partly replace the energy feed raw materials and save the application of corn, wheat, rice and other energy feeds in animal husbandry and aquaculture. The amount of compound feed should be between 5% and 10%.
高温复合菌发酵玉米饲料生产过程包括生产、饲料原材料和半成品的比例发酵过程后,筛查和混合发酵,成品包装过程,其中,高温复合细菌生产准备,材料处理,独特的所有混合发酵发酵玉米饲料生产的关键技术,这些微生物处理程序。例如，发酵玉米饲料的发酵过程与国内大多数微生物制剂生产企业和发酵饲料原料的发酵过程有很大的不同，发酵是在高温下进行的，在好氧炉中通过负压自动调节发酵。发酵时间为8 ~ 10h/批料，发酵温度为75±5℃。发酵玉米饲料中益生菌含量可达1.1×107CFU/g，纤维素酶1,280U/g，半纤维素酶4,720U/g，酸性蛋白酶320U/g，使产品既具有饲用微生物制剂功能，又具有饲用酶制剂功能。
The production process of corn feed fermented by high temperature composite bacteria includes production, proportion fermentation of feed raw materials and semi-finished products, screening and mixed fermentation, finished product packaging process, among which, high temperature composite bacteria production preparation, material processing, unique key technologies of all mixed fermentation corn feed production, and these microbial processing procedures. For example, the fermentation process of fermented corn feed is very different from that of most domestic microbial preparation enterprises and fermented feed raw materials. The fermentation is carried out under high temperature, and the fermentation is automatically regulated by negative pressure in the aerobic furnace. The fermentation time was 8 ~ 10h / batch, and the fermentation temperature was 75 ± 5 ℃. The content of probiotics in fermented corn feed can reach 1.1 × 107cfu / g, cellulase 1280u / g, hemicellulase 4720u / g, acid protease 320u / g, which makes the product not only have the function of feed microorganism preparation, but also feed enzyme preparation.
发酵玉米在猪、鸭、蛋鸡上的饲养试验结果表明，在蛋白质、氨基酸等营养成分相同的前提下，猪饲料配方成本可节省5.5 ~ 178.5元/吨。鸭饲料配方成本节约26.1~28.4元/吨;蛋鸡饲料成本可节约9.4~29.9元/吨。同时，它可以减少饲养动物的发病率，改善和提高动物肉制品的质量，改善饲养环境，稳定生产性能，减少抗生素的使用等优点。
The results of feeding experiment of fermented corn on pigs, ducks and laying hens showed that the formula cost of pig feed could be saved 5.5 ~ 178.5 yuan / ton on the premise of the same protein, amino acid and other nutrients. The formula cost of duck feed can be saved by 26.1-28.4 yuan / ton; the feed cost of layer can be saved by 9.4-29.9 yuan / ton. Meanwhile, it can reduce the incidence rate of animal feeding, improve and improve the quality of animal meat products, improve the feeding environment, stabilize the production performance, and reduce the use of antibiotics.
