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

What are the processing technologies for powdered honey?
Because honey is extremely viscous and difficult to dry, and the dried product is highly hygroscopic and inconvenient to use, in order to powder honey or honey-containing foods, it is necessary to add DE1-5 waxy corn starch to them, then spray-dry to powder them, and seal-package them to make honey or honey-containing powdered foods. First prepare DE1-5 enzymatically saccharified waxy corn starch. Adjust a 25%-35% waxy corn starch suspension, then add heat-resistant α-amylase to the suspension, and saccharify it at a temperature of 95°C

Analysis of Key Technologies and Economic Benefits of Deep-Buried Drip Irrigation for Cotton
Cotton "deep-buried" drip irrigation technology is another new high-efficiency water-use technology that has emerged following cotton subsurface hose micro-porous irrigation technology. This technology can utilize fertilizer and water with high efficiency, and its yield-increasing effect is obvious. I. Key Technologies 1. Irrigation The start of irrigation is at the cotton squaring stage. In the cotton region of northern Xinjiang, this is generally June 7-10, with irrigation carried out on a 3-day rotation cycle. If autumn is rainy, irrigation can be carried out on a 5-day cycle. Irrigation amount: at the squaring stage, each irrigation is 8 cubic meters per 667 sq m; at full flowering, 10 cubic

Methods for Breeding Introduced Pig Breeds and Key Points for Applying New Breeding Technologies
The continuous development and progress of science and technology have made it possible for people to explore natural laws and reveal biodiversity. The greatest advancement in pig breeding in the 20th century was breaking through 800 g/day in daily weight gain, achieving a lean meat rate of over 60%, a feed-to-meat ratio of 2.8:1, and slaughter pigs reaching over 90 kg body weight at 156 days, producing truly lean pigs. In recent years, with the continuous development of breeding theory and practice, pig breeding in countries with developed pig industries has gradually transitioned from breed selection to specialized composite line breeding, targeting different uses of each line in the crossbreeding system

Six Key Technologies for Pollution-Free Production of Edible Fungi
I. Improve the Ecological Environment The cultivation site should be chosen close to a water source, with good air flow, open space on all sides, and at least 1500 m away from livestock and poultry farms, breweries, residential areas and hospitals. Measures such as turning the soil, sun-bleaching and flooding should be adopted instead of chemical pesticides for disinfection. The water source and water quality must be clean and free of pollution. It is strictly forbidden to spray or soak mushrooms with sewage. Mushroom roots, dead mushrooms, insect-damaged mushrooms and discarded culture medium must not be stored inside or outside cultivation and processing facilities. II. Reasonably Select Raw Materials In strict accordance with the new requirements of WTO/SPS plant quarantine, the cottonseed hulls, wheat straw, corn

Detailed Explanation of 8 Edible Mushroom Food Processing Technologies
Fresh edible mushrooms have a high moisture content and cannot be stored for long after harvest; they soon open their caps, deteriorate, and become moldy, reducing or even losing their commercial value. At present, most edible mushrooms are sold fresh or as dried products, with very few deep-processed products, such as canned goods, which account for only 4%. In the future, people's requirements for the quality and varieties of edible mushrooms will become increasingly higher. Carrying out deep processing of edible mushrooms and developing a series of products is currently the main way to broaden the production field and sales market. 1. Mushroom preserves 1. Raw material selection: Select fresh mushrooms with medium-sized caps, natural color, intact mushroom shape, and no disease or insect spots as

Detailed Study on New Technologies for Pig and Chicken Nutritional Parameters and Formulations
Solving the global shortage of protein feed and the environmental pollution caused by nitrogen in livestock and poultry excreta has become one of the main themes of animal nutrition research in various countries, and is also one of the research contents of this project. The technical key lies in how to scientifically evaluate feed protein quality, formulate carbon-nitrogen and amino acid balanced diets, and improve the utilization rate of feed protein. The main contents of this study are as follows: (1) Using internationally recognized advanced experimental methods (ileo-rectal anastomosis pigs and caecectomized chickens), the digestible
