A formulation for voluntary oral administration of bioactive compounds to rodents. The semidsolid formulation having at least one thickening agent, a digestible sweetener selected from sucralose and calcium saccharin, a diluent agent, wherein the diluent agent is a powder with a granulometry between 300 and 800 μm, obtained from finely grounded seeds, cereal grains or cereal grain based diet for rodents, at least one flavor masking agent and a bioactive compound. The semi-solid formulation promotes voluntary feeding in rodents regardless of the bioactive compounds contained therein and without disruption of the metabolic pathways, therefore the semi-solid formulation has shown to be ideal for use in the oral administration of drugs and bioactive compounds to rodents. Use of the semi-solid formulation in the production of toxicant baits for rodents is also envisioned.

A composition that is a ruminant feed or a ruminant feed product for forming the ruminant feed includes a fatty acid-protected protein. The fatty acid-protected protein includes a protein source and a hydrogenated saturated fatty acid that coats the protein source. Various embodiments provide methods of feeding a ruminant and methods of forming the composition.

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.

Provided is a powder body obtained from a water-containing organic matter having a moisture content of 20% or less, a bacterial count of mesophilic aerobic bacteria of 10.sup.5/g or less, and a maximum exothermic peak by a differential thermal analysis method of 300° C. or higher.

An image capture device captures an image of crop after it has been processed by a kernel processing unit on a forage harvester. A size distribution indicative of the distribution of kernel fragment sizes in the harvested crop is identified from the image captured by the image capture device. A control system generates control signals to control a speed differential in the speed of rotation of kernel processing rollers based on the size distribution. Control signals can also be generated to control a size of a gap between the kernel processing rollers.

The invention relates to a device for determining particle size distribution in a bulk material, such as milled or grinded grain for animal feed. The device comprises an inlet for receiving at least a portion of the bulk material, a sorting mechanism for sorting the received bulk material. Said sorting mechanism comprises at least a first sorting device for sorting said received bulk material into at least two sorted partitions wherein the sorting device are capable of sorting different particle sizes and said at least two sorted partitions have different particle sizes. The invention further comprises a motor or actuator for vibrating said sorting device, a weighing system with at least one sensor for weighing the at least two sorted partitions sorted by said sorting mechanism and a data output for generating output data indicative of a weight of the at least two sorted partitions, so as to allow calculation of the particle size distribution in the bulk material received in the inlet and thus provide information regarding the particle size composition of the milled or grinded grain.

The present disclosure relates to an additive used in a methionine preparation process, and a methionine preparation method. The additive provided by the present disclosure is a mixture containing components A, B, and C; component A has a structure represented by the following general formula (1); component B has a structure represented by the following general formula (2); component C is silicone oil; RCON(CH.sub.3)CH.sub.2CH.sub.2SO.sub.3Na (1).

A corn cob type pet chew where the corn cob has improved digestibility. The improved digestibility is provided by digestive enzymes and/or incorporating selected locations of mechanical weaking so that the corn cob will also more readily reduce in size when chewed upon by the animal. The corn cob may also optionally include other additives, such as mineral fillers. The minerals may also assist in digestion.

A functional feed additive which may promote metabolism in livestock without the use of separate antibiotics, antibacterial agents and growth hormones, thereby increasing autoimmune cells to maximize the autoimmunity of livestock against various diseases, and which makes it possible to obtain meat containing increased amounts of unsaturated fatty acids beneficial to the human body and which has an effect of significantly reducing the complex odor of livestock excrement by removing ammonia gas (NH.sub.3) generated from livestock excrement.

The present invention describes a bio-based process to produce high quality protein concentrate (HQPC) by converting plant derived celluloses into bioavailable protein via aerobic incubation, including the use of such HQPC so produced as a nutrient, including use as a fish meal replacement in aquaculture diets.
