[0024] figure 1 The flow chart of the preparation method of the Jatropha curcas leaf extract feed additive provided by the embodiment of the present invention. Such as figure 1 Shown, the preparation method of Jatropha curcas leaf extract feed additive provided by the invention may further comprise the steps:

[0025] Step 1. Place the collected fresh leaves of Jatropha curcas in a shaded place to dry in the shade.

[0026] Step 2, preparing Jatropha curcas leaf powder from the shade-dried Jatropha curcas leaves.

[0027] In this step, the step of preparing Jatropha curcas leaf powder from the shade-dried Jatropha curcas leaves may be specifically: crushing the shade-dried Jatropha curcas leaves, and then passing through 40 meshes to obtain the Jatropha curcas leaf powder.

[0028] Step 3: Take Jatropha curcas leaf powder and ethanol, put the two in a conical flask and mix evenly, and prepare a mixed solution of Jatropha curcas leaves and ethanol.

[0029] Preferably, the ...

Abstract

The invention provides a preparation method and an application of a jatropha curcas leaf extract feed additive. The method comprises the following steps of: drying collected fresh jatropha curcas leaves in the shade; preparing the jatropha curcas leaves dried in the shade into jatropha curcas leaf powder; evenly mixing the jatropha curcas leaf powder and ethyl alcohol in a conical flask (a solid-liquid ratio is 1g:40mL) to obtain the mixed liquor of the jatropha curcas leaf and the ethyl alcohol; putting the mixed liquor of the jatropha curcas leaf and the ethyl alcohol in a constant-temperature water bath shaking table at a temperature of 50DEG C, carrying out suction filtration after the mixed liquor is placed for 80min, and then, carrying out centrifugation by a high-speed refrigeratedcentrifuge at a temperature below 4DEG C for 10min, and collecting supernate; and transferring the supernate to a rotary evaporator, and carrying out concentration processing to obtain concentrated concrete. The jatropha curcas leaf extract is used as the feed additive which has an effect similar to an antibiotic feed additive, the antibiotic feed additive can be replaced, livestock is acceleratedto grow, and the intestinal health of the livestock is regulated and controlled.

Description

technical field [0001] The application belongs to the technical field of feed additives, and in particular relates to a preparation method and application of a Jatropha curcas leaf extract feed additive. Background technique [0002] Adding antibiotics in livestock and poultry production will destroy the microecological balance in the intestinal tract of livestock and poultry, and lead to bacterial resistance. In addition, antibiotic residues in livestock and poultry products will threaten human health. [0003] Jatropha curcas leaves have certain pharmacological effects. The current research on Jatropha curcas leaves is mainly its application in human medicine, for example, to explore the effects of Jatropha curcas leaf extracts on anti-oxidation, anti-virus, antibacterial and other aspects. There are no systematic reports on the application of Jatropha curcas leaf extract in the growth and development of livestock and poultry, intestinal development, digestive physiology,...
