This invention belongs to the technical field of virus detection, specifically relating to a PCR detection kit for the simultaneous detection of four DNA viruses in waterfowl and its application. The PCR detection primer set for the simultaneous detection of four DNA viruses in waterfowl of this invention is the optimal primer set obtained through experimental screening. The kit composed of these primers can rapidly and specifically amplify and diagnose Muscovy duck parvovirus, duck plague virus, duck adenovirus type 3, and duck circovirus simultaneously, exhibiting high specificity and sensitivity. It can accurately and rapidly identify MDPV, DPV, DAdV-3, and DuCV, and can complete quantitative real-time PCR detection in approximately 50 minutes. The kit is simple and practical to operate, achieving efficient simultaneous detection of four viruses, shortening the detection cycle, increasing sensitivity by 10-1000 times, significantly improving early disease diagnosis capabilities, significantly reducing the misdiagnosis rate of diseases in poultry farms, and contributing to the sustainable development of the poultry farming industry.

This invention discloses an automatic feeding device and method for waterfowl farming, belonging to the field of waterfowl farming technology. The device includes a feeding cage, an intelligent feeding mechanism, a soil improvement mechanism, and a monitoring and control mechanism. The feeding cage consists of a supporting cage, a bottom-lifting cage, a laterally extending cage, and a transition cage, forming a closed waterfowl farming environment. Through this method, the lifting and laterally extending feeding cage structure allows the device to be close to the ground and extend between adjacent fruit tree trunks, strictly limiting the waterfowl's activity range to the target area, preventing them from pecking at fruits and branches, and resolving the conflict between grazing and fruit tree growth. The environmental control mechanism provides a comfortable living environment for the waterfowl, and the cage structure remains closed during extension and lifting. The soil improvement mechanism enables in-situ fermentation and decomposition of manure, achieving an ecological closed loop of "farming-weeding-fertilizing."

The present disclosure pertains to an innovative method for attracting waterfowl, specifically designed to enhance the efficacy of waterfowl hunting by replicating natural water sounds that mimic the activities of waterfowl, such as splashing, swimming, fishing, and mating. The invention utilizes a mechanical apparatus equipped with a sound-producing puck attached to a reciprocating pole, driven by a motor or by use by hand. The puck is designed to strike the water at controlled intervals, creating a variety of water sounds that effectively mimic natural waterfowl sounds, thereby attracting the birds. This method is intended for use with either standalone devices or in conjunction with existing waterfowl decoys to provide hunters with a novel and more effective way to attract waterfowl by using sounds that replicate natural waterfowl behavior.

This invention discloses a Cherry Valley duck hepatoma cell line (DMH) and its applications. It relates to the field of biotechnology. It provides a method for establishing immortalized duck hepatoma cells and related applications. This invention has good market demand and application value. It provides stable cell material for scientific research on duck viral hepatitis virus and the development and production of vaccines. Based on a duck hepatoma model induced by diethylnitrosamine (DEN), this invention obtains a highly active and pure duck hepatoma cell line through standardized primary tumor cell isolation, culture, and identification procedures. This cell line can efficiently support the proliferation of waterfowl hepatotropic viruses, and is particularly suitable for the culture of duck viral hepatitis virus, providing an ideal cell carrier for waterfowl viral pathogen research and vaccine development.

The waterfowl decoy deployment system includes a hub assembly including a central hub and a base coupled to the central hub. The system further includes a motor assembly attached to the base. The motor assembly includes a drive shaft and a propeller coupled to the drive shaft. The drive shaft is rotatable about a rotational axis to propel the hub assembly in a linear direction in an aqueous environment. A plurality of arms are coupled to the central hub and extend radially outward from the central hub.

This invention discloses a reagent, kit, method, and application for the simultaneous detection of waterfowl reoviruses MDRV and NDRV, belonging to the field of biodetection and molecular diagnostics technology. This invention designs specific RPA primers and crRNA for MDRV and NDRV respectively, utilizing the trans-cleavage activity of LbCas12a on ssDNA reporter probes and LwaCas13a on ssRNA reporter probes to output ROX and FAM fluorescence signals respectively in the same reaction tube, thereby achieving simultaneous detection and genotyping of the two viruses. The detection limit for both MDRV and NDRV is 1 copy number / µL, with good specificity. Detection can be completed within 30 minutes, exhibiting clinical diagnostic efficacy comparable to the gold standard qPCR. It has the advantages of simple operation, rapid detection, high sensitivity, strong specificity, and suitability for field applications.
