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.

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.

The present invention aims to provide an agent for preventing or ameliorating stress disorders, which agent is highly safe and effective, causes less side effects, and can be continuously used for a long time.

One embodiment of the present invention is an agent for preventing or ameliorating stress disorders comprising, as an active ingredient, a lactic acid bacterium Lactobacillus delbrueckii subspecies lactis or a lactic acid bacterium-derived ingredient therefrom.

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.
