Abstract

The invention discloses a use of a traditional Chinese medicine fermented product as an antibiotic substitute in feed. The use method comprises weighing 25-35 parts of pilose asiabell root, 10-20 parts of wolfberry, 15-25 parts of medicinal cyathula root and 25-35 parts of spina date seeds, mixing the materials, crushing the mixture to obtain traditional Chinese medicine powder, carrying out sterilization, preparing a culture solution containing, by mass, 0.2-0.4% of starch, 0.6-0.8% of ammonium sulfate, 0.2-0.4% of dipotassium hydrogen phosphate, 0.1-0.2% of potassium dihydrogen phosphate, 0.05-0.07% of magnesium sulfate, 0.04-0.06% of calcium chloride and 0.02-0.04% of yeast extract paste, adjusting pH to 7.0-7.2, carrying out sterilization, mixing the traditional Chinese medicine powder and the culture solution according to a weight ratio of 1: 40-50 to obtain a mixed culture medium, adding a compound Hiiranlactone A into the mixed culture medium so that a concentration is in a range of 50-60 micrograms per gram, inoculating the mixed culture medium with 4-6% of bacillus subtilis, carrying out fermentation cultivation for 24-48h, controlling pH to 7.0-7.2, and carrying out drying at a low temperature until water content is in a range of 6-8% to obtain the traditional Chinese medicine fermented product. The traditional Chinese medicine fermented product can significantly improve fattening sheep growth performances.
本发明公开了中药发酵品作为抗生素替代物在饲料中的应用,包括:称取党参25~35份、枸杞10~20份、川牛膝15~25份、酸枣仁25~35份,混合粉碎,得到中药粉末,灭菌备用;配制培养液,含淀粉0.2~0.4%、硫酸铵0.6~0.8%、磷酸氢二钾0.2~0.4%、磷酸二氢钾0.1~0.2%、硫酸镁0.05~0.07%、氯化钙0.04~0.06%、酵母膏0.02~0.04%,均为质量百分含量;调节pH值为7.0~7.2,灭菌备用;中药粉末与培养液按照重量比1:40~50混合得到混合培养基,添加化合物Hiiranlactone A,使其浓度为50~60μg/g,再按4~6%的接种量接入枯草芽孢杆菌发酵培养24~48小时,控制pH值为7.0~7.2;低温烘干至水分6~8%,即得中药发酵品。本发明提供的中药发酵品可以显著提高育肥羊的生长性能。
