The invention relates to the field of animal feed, specifically to a full-automatic milk feeder for newborn livestock. The full-automatic milk feeder for the newborn livestock is composed of a feed box, a stirring box and a feeding unit, wherein the feed box is located above the stirring box, and the feed box and the stirring box are connected via a movable plate; the interior of the stirring box is provided with a stirring unit; and the feeding unit comprises a feeding pipeline and a feeding mouth, and a valve is arranged between the feeding pipeline and the feeding mouth. The full-automatic milk feeder for the newborn livestock provided by the invention realizes full-automatic feeding and does not need manual-stirring of materials; meanwhile, the milk feeder has the advantages of automatic batching, fixed-time feeding and automatic cleaning, so true full automation is achieved; material resources, human resources and financial resources are saved; bacterial reproduction is inhibited; and safety of liquid milk for the newborn livestock is guaranteed.

The invention discloses artificial colostrum capable of improving survival rate of young newborn meat rabbits. The artificial colostrum is prepared by the following steps of using whole milk powder as basis, adding rabbit serum immunoglobulin, whey protein powder, glucose, lysozyme, complex enzyme preparation, multiplex vitamin of electrolyte, and trace elements, and uniformly mixing, so as to obtain the dry powder type artificial colostrum. The artificial colostrum has the advantages that the artificial colostrum can be used for replacing colostrum of a female rabbit, the problem of a newborn rabbit lacking of colostrum because the female rabbit has no colostrum or lacks of colostrum after giving birth to the newborn rabbits is effectively solved, the immunity of the young rabbit is obviously enhanced, and the survival rate of the young rabbit is improved.

The invention relates to an intelligent temperature control safety feeding bottle. The intelligent temperature control safety feeding bottle comprises a bottle body, a bottle neck and a suction nozzle; a bearing plate is arranged on the upper end of the bottle neck, and the bearing plate is combined with the bottle neck through screw threads; the lower surface of the bearing plate is provided with a temperature control layer; the temperature control layer expands with heat and contracts with cold; elastic current limiting plates are arranged below the temperature control layer, and the current limiting plates are made of a heat conductive material; the current limiting plates are arranged in rotational symmetry on the inner wall of the bottle neck, diversion holes are formed in the current limiting plates, and when the current limiting plates are perpendicular to the bottle neck, the current limiting plates are stacked in parallel in the vertical direction, meanwhile the diversion holes in the current limiting plates are communicated in a right-facing mode; when the current limiting plates are bent upwards or downwards, the diversion holes are staggered instead of being communicated; under the natural condition, the current limiting plates are arched upwards, and the diversion holes are staggered. The feeding bottle is novel and unique in structure, and can effectively guarantee the appropriate temperature of the drink, prevent from scalds and excessive coldness, give a baby the most intimate care, meanwhile relieve the burden of parents.

The invention discloses an antibacterial touch storage box cover plate for refrigerators, and relates to the technical field of a refrigerator storage box cover plate. The antibacterial touch storagebox cover plate for the refrigerators comprises a refrigerator storage box cover plate component and a storage box cover plate glass touchpad, wherein the refrigerator storage box cover plate component comprises a storage box glass shelf and a storage box glass shelf frame; the storage box glass shelf is matched and arranged in the storage box glass shelf frame and comprises a first glass substrate; one side face of the first glass substrate is orderly coated with an antibacterial coating and a dense protective coating from inside to outside; the storage box cover plate glass touchpad comprises a second glass substrate; and the outer surface of the second glass substrate is orderly coated with an antibacterial coating and a dense protective coating from inside to outside. As the outer surfaces of the refrigerator storage box cover plate component and the storage box cover plate glass touchpad are orderly coated with the antibacterial coatings and the dense protective coatings, the chance of bacterial infection, reproduction and cross-infection is reduced, and the antibacterial property of the storage box cover plate is improved.

The invention discloses a method for separating and detecting diphenylamine and rhodamine B by using a gold nano channel. A PC (polycarbonate) membrane is used as a template, and gold is deposited on hole walls of the PC membrane template with nano aperture by adopting a chemical deposition method to obtain a functional hydrophobic gold nano channel; diphenylamine serving as a hydrophobic molecule easily passes through the hydrophobic gold nano channel; the rhodamine B is a cationic compound, belongs to a hydrophilic molecule and can not migrate in the hydrophobic gold nano channel; separation of the diphenylamine and the rhodamine B is realized according to the difference of the hydrophobic property of the two; the transmission quantity of each of the diphenylamine and the rhodamine B passing through the gold nano channel is detected by using an ultraviolet detector. The method can be applied to the fields of contemporary medicinal chemistry, agricultural chemistry, food chemistry and biochemistry, and is particularly used for separating carcinogenic substances such as food dyes and protecting food safety and body health.
