报告主要说明利用风化煤制取腐植酸——微生物蛋白饲料产品的方法。并通过试验证明,此方法在技术上、经济上是可行的。文中既引用了前人利用风化煤中腐植酸的肯定结论,又列举了作者通过中试研究,产生的生产工艺流程、及产品的特性、安全性和产品在畜禽饲养中的良好效益。报告中指出,制取腐植酸——微生物蛋白饲料的生产工艺,其主要部分由CandidaLipotytica 47~#的特性所决定。该菌对外界条件要求不严格,对碳源的适应性强。通过该工艺生产的产品,含粗蛋白质45—55％,含改性腐植酸15—25％,含有动物所必需的氨基酸、多量元素、微量元素、维生素。产品无毒。在喂养畜禽中,可50％替代进口淡鱼粉,猪的粗蛋白可消化率66—75％,可同进口淡鱼粉相媲美。鸡的喂养结果:日增重提高26.2％,成活率提高20％,饲料报酬提高26.7％。报告列举年产5000吨规模的工厂,产品成本2000元/吨以下。报告指出,发展腐植酸——微生物蛋白饲料,废弃的风化煤被利用,社会效益显著,企业的经济效益可观。
The report mainly describes the use of weathered coal preparation of humic acid - microbial protein feed products. And through the experiment proved that this method is technically and economically feasible. In this paper, both predecessors make use of weathered coal humic acid affirmative conclusion, also cited the author through the pilot study, resulting in the production process, and product characteristics, safety and product in animal husbandry and good benefits. The report pointed out that the production of humic acid - microbial protein feed production process, the main part of CandidaLipotytica 47 ~ # characteristics of the decision. The bacteria on the outside conditions are not strict, adaptable to carbon sources. Products produced by this process contain 45-55% of crude protein, 15-25% of modified humic acid, amino acids, trace elements, vitamins, essential for animals. Non-toxic products. In the feeding of livestock and poultry, 50% can replace imported fishmeal, the digestibility of crude protein in pigs is 66-75%, comparable with that of imported fishmeal. Chicken feeding results: daily gain increased by 26.2%, survival rate increased by 20%, feed increased by 26.7%. The report lists a factory with an annual output of 5,000 tons, product cost 2,000 yuan / ton. The report pointed out that the development of humic acid - microbial protein feed, abandoned weathered coal is used, social benefits significantly, the economic benefits of enterprises considerable.
