Abstract: Disclosed are a method for preparing a porcine-derived interferon-delta 5 (pIFN-?5) and an application of the pIFN-?5, where the method for preparing pIFN-?5 includes the following steps: step S1, obtaining a DNA fragment containing pIFN-?5 gene through reverse transcription-polymerase chain reaction (RT-PCR) amplification by using the total RNA of pretreated porcine small intestinal epithelial cells IPEC-J2; step S2, inserting the DNA fragment containing pIFN-?5 gene into an exogenous expression vector to construct a recombinant expression vector for expressing the pIFN-?5 gene; and step S3, introducing the recombinant expression vector into a suitable host cell, and driving the host cell to express the pIFN-?5 gene to obtain the pIFN-?5. The recombinant pIFN-?5 protein is used to prepare drugs or preparations for inhibiting infection of porcine epidemic diarrhea virus (PEDV), porcine transmissible gastroenteritis virus (TGEV), porcine delta coronavirus (PDCoV) and porcine rotavirus (PRoV).

Abstract: The present disclosure relates to a brick making system, a production control method, a production control device, a production system, a production equipment, and a computer-readable record medium. The brick making system includes: a brick making machine; a bottom material distribution device connected to one side of the brick making machine to feed bottom material to the brick making machine in a first direction; and a surface material distribution device connected to the other side of the brick making machine adjacent to the one side, to feed surface material to the brick making machine in a second direction. The bottom material distribution device and the surface material distribution device are arranged at adjacent two sides of brick making machine, respectively, so that the occupied space of the brick making system can be reduced.
