Research Progress on Detection Technologies for Porcine Circovirus
Porcine circovirus disease is a class of viral infectious diseases caused by porcine circovirus (PCV) infection and characterized by immunosuppression, with the main clinical manifestation being postweaning multisystemic wasting syndrome in piglets caused by PCV-2. This article reviews the research progress in recent years, both domestically and internationally, on detection technologies for this virus, including virus isolation, electron microscopy, polymerase chain reaction, indirect immunofluorescence assay, immunohistochemistry, enzyme-linked immunosorbent assay, and in situ nucleic acid hybridization. Porcine circovirus disease

Major progress made in project to control soybean yield reduction from continuous and alternating cropping
The reporter learned from relevant departments that the project "Research and Demonstration of Key Technologies for Controlling Soybean Yield Reduction under Continuous and Alternating Cropping," tendered by the Municipal Science and Technology Bureau, has achieved major progress after two years of scientific research. The project was carried out in Yilan and Bayan counties, the two counties with the largest soybean area in Harbin. Through key technology research, soybean varieties resistant to continuous and alternating cropping were selected, including Kenfeng 16, Heinong 48, Kangxian 4, and Hefeng 47. A formula fertilization technique was proposed with 45 kg of nitrogen, 60-67.5 kg of phosphorus, 67.5-75 kg of potassium, and

Current Status and Progress of Research on Porcine Ophthalmic Diseases
Researchers in veterinary medicine at the University of Florida in the United States used pigs as experimental subjects and specially treated the feed provided so that it created a zinc-deficient condition. As a result, this treatment group may have caused chronic damage to the pigs' retinas, and it may be related. Veterinary ophthalmology experts have completed monitoring changes in blood, skin, body weight and major organs in young piglets and older pigs. The pig eye is very similar in structure to the human eye. This group of researchers has
