As a key engine for enhancing the level of agricultural modernization and safeguarding food security, the digital reconstruction of the entire feed industry chain is driving the feed industry to transform from traditional scale expansion toward high-quality, high-efficiency, and green sustainable development. From the perspective of new quality productive forces, building a solid defense line for food security, promoting the high-quality development of the feed industry, and accelerating the realization of rural revitalization goals constitute the contemporary value of the digital reconstruction of the entire feed industry chain. This article focuses on the upstream planting industry, the midstream feed industry, and the downstream breeding industry, and clarifies the strategic priorities of the digital reconstruction of the entire feed industry chain, namely building a smart raw material supply system for the planting industry, promoting the intelligent transformation of the production processes of the feed industry, and removing the bottlenecks in the implementation of digital and intelligent services in the breeding industry. On this basis, industry entities should take factor reconstruction, scientific and technological innovation, and digital infrastructure as focal points to improve the smart supply level of raw materials in the feed industry, achieve full-process autonomous control of feed production, facilitate the implementation of digital and intelligent services in the feed industry, and accelerate the digital reconstruction of the entire feed industry chain.
Against the background of accelerating the building of an agricultural powerhouse and promoting comprehensive high-quality development of agriculture, the feed industry, as a key component of modern agriculture, has its industry chain resilience growth of great significance for realizing Chinese-style agricultural and rural modernization. Digital village construction driving the resilient growth of the feed industry chain helps promote the rapid development of the breeding industry and promotes the green development of the feed industry, thereby consolidating the foundation for agricultural modernization. As a key driving force for high-quality development, digital village construction, relying on data-driven approaches, technology transformation, and intelligent management and control, provides a core driving force for the resilient growth of the feed industry chain. In order to fully leverage the enabling effect of digital village construction in driving the resilient growth of the feed industry chain, it is necessary to build a full-chain data integration and sharing platform, accelerate the systematic construction of digital infrastructure, and deepen the integrated application of digital technology across all links, so as to provide theoretical references and practical guidance for driving the resilient growth of the feed industry chain.
Water is a basic nutrient for livestock and poultry health and the maintenance of production, and the safety of drinking water and the degree of water quality optimization are key factors determining livestock and poultry health and breeding benefits. Magnetized treatment, as a green water quality improvement method, achieves physical modification of drinking water by weakening intermolecular hydrogen bonds, restructuring the microscopic cluster structure of water, reducing water surface tension, viscosity, and density, and enhancing permeability, pH value, dissolved oxygen, and electrical conductivity. Magnetized water can effectively enhance the antioxidant capacity and immunity of livestock and poultry, and improve their production performance. At present, the complete mechanism by which magnetized water regulates the physiological metabolism of livestock and poultry remains unclear, and a standardized process parameter system adapted to different water sources and livestock and poultry species has not yet been established. This article systematically reviews the preparation methods and classification of magnetized water, its mechanisms of action, and research progress on its application in livestock and poultry production, aiming to provide a reference for the research and utilization of magnetized water in the livestock and poultry industry.
The experiment aimed to investigate the effects of different planting densities on the agronomic traits and quality of fenugreek. A single-factor experimental design was adopted, with five planting density treatments, namely 3.30×105 (group A), 6.60×105 (group B), 1.00×106 (group C), 1.33×106 (group D), and 1.66×106 plants/hm2 (group E), with three replicates per group, and the agronomic traits and nutritional quality indices of fenugreek were measured. The results showed that different planting densities had significant effects on plant height, hay yield, and seed yield of fenugreek (P<0.05), among which group C had the highest plant height, hay yield, and seed yield. In terms of nutritional quality, different planting densities had significant effects on the concentrations of crude protein (CP), soluble sugar (SS), ether extract (EE), trigonelline, and seed EE (P<0.05), among which group E had the highest CP content, group A had the highest SS content, and group C had the highest EE, trigonelline, and seed EE concentrations. The comprehensive evaluation showed that group C had the best agronomic traits and nutritional quality. The study shows that an appropriate planting density (1.00×106 plants/hm2) can increase the plant height, hay yield, and concentrations of EE, trigonelline, and seed EE of fenugreek, while maintaining relatively high concentrations of CP and SS.
Immature tomato fruit is the main by-product generated during the industrial harvesting of tomatoes. It is rich in nutrients such as crude protein, vitamins, minerals, and amino acids, and possesses resource advantages for development as unconventional feed. However, immature tomato fruit contains a large amount of α-tomatine, which limits its direct feeding use. This not only causes resource waste but also brings environmental pollution. Existing degradation technologies for α-tomatine include physical treatment, chemical treatment, and biological treatment, among which biological treatments such as microbial fermentation and ensiling have shown good potential in reducing α-tomatine content. In addition, treated immature tomato fruit or its processing by-products can partially replace the diets of broilers and ruminants, exerting positive effects on growth performance and antioxidant capacity. This article systematically reviews the resource status, nutritional characteristics, anti-nutritional effects, and key technologies for α-tomatine degradation of immature tomato fruit, and evaluates its application effects in livestock and poultry production, aiming to provide a reference for the feed utilization of this by-product and the recycling of agricultural resources.
