Detailed Explanation of the Southern Pig-Biogas-Fruit Ecological Model and Supporting Technologies
"Pig----Biogas----Fruit" makes use of resources such as mountain land, farmland, water surfaces, and courtyards, adopting the "biogas digester, pigsty, and toilet" three-in-one project, centering on leading industries, and carrying out comprehensive utilization of the "three biogas products" (biogas, biogas residue, biogas slurry) according to local conditions, achieving efficient use of agricultural resources, ecological environment construction, improved agricultural product quality, and increased farmer income. The project's orchard (or vegetable plot, fish pond, etc.) area, pig breeding scale, and biogas digester volume must be reasonably combined. The model engineering technologies include pigsty construction, biogas digester engineering construction

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

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

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
