This invention provides a method for monitoring and evaluating the risk of pathogenic bacteria transmission in poultry farm feces, belonging to the field of livestock and poultry biosecurity control technology. The method includes evaluating the risk of Salmonella transmission during the poultry physiological cycle, assessing the risk of antibiotic resistance associated with drug administration behavior, and monitoring the function during composting based on microbial community structure and metabolic function. This invention can accurately locate the highest-risk nodes of pathogen contamination and antibiotic resistance evolution during the breeding cycle, solving the problem of inaccurate identification of risk sources in existing technologies and avoiding poultry product contamination due to missed risk assessments. It overcomes the single-dimensional limitation of existing technologies that only detect the quantity of pathogens, comprehensively evaluating pathogen risk from phenotypic, molecular, and functional levels. The assessment results are more in line with the actual biosecurity needs of poultry farming, ultimately reducing the safety risks of poultry product contamination and the spread of antibiotic resistance.

The present invention proposes an innovative packaging for poultry products, combining a plastic tray, a cling film and a reticulated net positioned on top. This net, composed of semi-rigid meshes, is designed to offer reinforced protection against perforations and mechanical tears that frequently occur during transport and handling on the shelf.The net allows the mechanical forces to be distributed over a larger surface, thus protecting the fragile cling film, in particular at the longitudinal ends often exposed to the risk of tearing. In addition, pieces of plasticized paper are placed at the ends to cover the vulnerable pygostyle parts reinforcing the durability and strength of the packaging.The net also offers a better grip and ensures an aesthetic presentation of the product, facilitating handling and traceability thanks to a label fixed on the net. Overall, this invention aims to improve both the durability and ergonomics of the packaging while ensuring optimal conservation of poultry products.

This invention discloses an intelligent scheduling method and system for temperature-controlled paths in the cold chain distribution of poultry products, belonging to the field of cold chain logistics technology. By dividing the poultry product cold chain distribution network into several sub-paths and deploying temperature sensors, humidity sensors, and multispectral imaging units, a data acquisition time series is constructed to achieve multi-source monitoring of the environmental conditions in the distribution process. Based on image data, high-incidence temperature control failure areas are standardized and visual characteristics of quality deterioration are detected, enabling early identification of potential temperature control risks. Temperature control disturbance characteristic values ​​are calculated by combining temperature signals, humidity signals, and visual information, and the disturbance evolution amplitude and risk trend values ​​are calculated based on the time series to form a comprehensive temperature control characteristic value. The node temperature control correlation index is calculated and combined with thresholds for screening, enabling dynamic scheduling and early warning of abnormal temperature control paths. This improves temperature control accuracy and sensitivity, allows for rapid location of abnormal paths, and enhances the safety and management efficiency of the poultry product cold chain distribution.

This invention discloses a knowledge graph-based method and system for evaluating livestock and poultry products, relating to the field of smart animal husbandry technology. The method includes: collecting multi-source data from the entire livestock and poultry breeding and processing chain and preprocessing it to obtain standardized real-time data and historical data streams; constructing a full-link causal-temporal knowledge graph model with causal and temporal information; based on the full-link causal-temporal knowledge graph model, constructing an uncertainty measurement causal knowledge graph, extracting real-time monitorable source event combinations, and forming a precursor signal pattern library; matching the standardized real-time data with real-time data in the historical data stream and the precursor signal pattern library to obtain specific precursor pattern matching events that are triggered; and using these specific precursor pattern matching events as the starting point. This invention forms a complete closed-loop evaluation and decision support system from data perception, knowledge construction, real-time reasoning, accurate decision-making to model self-evolution.

This invention provides a kit for the simultaneous detection of nine flavor nucleotides in livestock and poultry products. The flavor nucleotides are cytidine monophosphate, uridine monophosphate, guanylic acid, inosine monophosphate, adenosine monophosphate, hypoxanthine, inosine, adenosine diphosphate, and adenosine triphosphate. The kit includes: a high-concentration extraction reagent, a standard curve solution, a high-concentration phosphate buffer solution, pH adjustment solution A, and pH adjustment solution B. The high-concentration extraction reagent is perchloric acid; the standard curve solution is a mixed solution of the nine flavor nucleotides; the high-concentration phosphate buffer solution is a solution of potassium dihydrogen phosphate and dipotassium hydrogen phosphate; pH adjustment solution A is sodium hydroxide; and pH adjustment solution B is phosphate. This invention also provides a method for the simultaneous detection of the nine flavor nucleotides using the above kit. This invention enables the simultaneous determination of the content of nine flavor nucleotides in livestock and poultry products. The method is simple, rapid, accurate, and sensitive, and can be used for batch determination, showing good prospects for practical application.

The present application relates to the field of agricultural science and technology, in particular to a poultry cultivation method of a traditional Chinese medicine secret recipe, which enhances immunity: the polysaccharide and alkaloid components in traditional Chinese medicine can activate the immune organs of chickens and ducks, reduce the occurrence of common diseases such as avian influenza and enteritis, improve the survival rate, reduce the breeding loss, improve production and meat quality, replace chemical antibiotics and growth promoters with traditional Chinese medicine, and the traditional Chinese medicine residue in chicken and duck meat and eggs is far below the national standard, meeting the requirements of green and organic farming, adapting to the high-end market, and regulating the body more gently: traditional Chinese medicine emphasizes syndrome differentiation and regulation, can improve the intestinal flora of chickens and ducks, relieve stress (such as group transfer and changes in temperature and humidity), is suitable for long-term feeding, has no obvious toxic and side effects on chickens and ducks, and solves the problem of the existing poultry cultivation method, which needs to use chemical antibiotics and hormones to promote the health of poultry during cultivation, resulting in poor edible safety of poultry products due to drug residues.
