The invention discloses the feeds for improving laying rate of laying hen, and ingredient and its parts by weight are：40 60 parts of corn flour, 8 12 parts of dregs of beans, 12 parts of vegetable oil, 24 parts of coptis alkaloid, 23 parts of vitamin A, 25 parts of vitamin E, 12 parts of phytase.It has the beneficial effect that：Feedstuff prepared by the present invention is easy to get, of low cost, can effectively facilitate Egg Production of Laying Hens, and be free of non-organic additive, have good ecological benefits；The method safety for extracting coptis alkaloid is convenient, reduce energy consumption, and impurity content is few in extract, convenient for the raising of coptis alkaloid content in subsequent step, and hydrochloric ethanol extract is when repeatedly being extracted, the extracting solution of last time filtering gained can be used for the first time solvent when the extraction of the next group coptis, to reduce solvent dosage. |
