A method and system are provided for preparing micro-ingredient feed additives for use in designated feed rations. A micro-ingredient system of the invention includes a plurality of bins that store designated micro-ingredients therein. A master controller of the delivery system provides signals to control system components based on programmed commands corresponding to micro-ingredient batches to be prepared. Slide gate mechanisms are used to prevent loss of micro-ingredients delivered to a receiving receptacle of the system. During delivery of the micro-ingredients to the receptacle and during processing, the micro-ingredients can become airborne and subsequently lost. The slide gate mechanisms also provide controlled access to the receiving receptacle to prevent system errors such as contamination of ingredients in the receptacle, or improper batching of a prescribed micro-ingredient mixture to be delivered to a designated feed ration.

The present invention is directed to plants that display an improved oil quantity phenotype or an improved meal quality phenotype due to altered expression of an HIO nucleic acid. The invention is further directed to methods of generating plants with an improved oil quantity phenotype or improved meal quality phenotype.

This invention discloses method for feeding Hermetia illucens and used as for preparing composite material of puparium, which comprises the following steps: S1, dry Hermetia illucens pupariums and grind them into powdery, S2, adding powdery of Hermetia illucens pupariums into sodium hydroxide aqueous solution, stirring, separating and filtering, S3, adding the pupariums into hydrochloric acid solution, stirring, separating and filtering; S4, placing the pupariums into sodium hydroxide aqueous solution, stirring, separating and filtering; S5, drying the pupariums, and screening out the granular pretreated powder of the Hermetia illucens pupariums. The invention also disclose preparation method of composite material and thin film of Hermetia illucens pupariums and antibacterial and antimildew additive. The method can effectively improve the yield of chitosan in Hermetia illucens pupariums, and the prepared pupariums powder can be used for preparing polymer composite fibers and thin films of the Hermetia illucens pupariums, thus, the antibacterial effect is greatly improved. A new antibacterial and antimycotic additive can be obtained by compounding the powder of Hermetia illucens pupariums with the powder of oyster shell.

Disclosed is a method for preparing an attapulgite-based pH-responsive antibacterial material, including: directly spraying a natural aldehyde-based antibacterial agent onto an attapulgite powder under stirring, and constantly stirring the attapulgite powder for 20-30 min; grinding the attapulgite powder in a ball mill for 30-60 min to obtain a ground attapulgite powder; placing the ground attapulgite powder in a stirred tank, and spraying a chitosan-citric acid aqueous solution onto the ground attapulgite powder; after spraying, constantly stirring the ground attapulgite powder for 30-120 min; and finally drying the ground attapulgite powder to obtain a dried attapulgite powder, sieving the dried attapulgite powder to obtain a sieved attapulgite powder, and packaging the sieved attapulgite powder to obtain the antibacterial material.
