The disease has various causes, including infections by pathogens such as bacteria, viruses, and mycoplasma. Clinical symptoms are complex and require specific laboratory methods for accurate diagnosis. Traditional diagnostic methods for mastitis have low accuracy, while molecular biology testing shows great development prospects. Techniques such as microbial culture kits and loop-mediated isothermal amplification （LAMP） are expected to improve the accuracy of mastitis diagnosis and treatment precision. Antibiotics are commonly used for treatment, but they can easily cause bacterial resistance and drug residue problems. Therefore, new drugs are needed for mastitis treatment. Recent studies have shown that bacteriophages may be used as alternatives to treat mastitis, and some plants and their derivatives have antibacterial properties. Natural secretion factors such as lactoferrin and phospholipase A2 also have therapeutic potential, but further research is needed. This paper summarized the current research status of diagnostic and treatment methods for mastitis in dairy cows and provides references. Reference | Related Articles | Metrics | Comments（0）

However, at the same time, the amount of waste such as feces and sewage produced by these farms has increased, and most of them cannot be properly treated. The accumulation of manure in the production area not only causes pollution to the surrounding soil, air, and water bodies but also affects the normal breeding and production order of the cattle farm. This seriously harms the ecological environment and affects the green and sustainable development of the cattle industry. Therefore, the problem of treating and utilizing cow manure as a resource needs to be urgently addressed. To stabilize and safely handle the manure, this paper proposed to utilize the manure from large-scale cattle farms as a resource. This not only solved the problem of manure pollution in cattle farms but also maximized the utilization of manure resources, which was of great significance. This paper analyzed the nutritional composition of cow manure and the environmental pollution caused by manure from large-scale cattle farms. The purpose, principles, and expected effects of resource utilization of manure were briefly described. Existing methods of cow manure resource utilization were also introduced, including energy utilization, substrate utilization, feed utilization, fuel utilization, fertilizer utilization, and the reuse of oxidized pond fermentation. By analyzing various resource utilization technologies and applying them according to specific situations, or implementing multiple technologies in combination, the limitations of a single technology can be avoided. This paper provided a reference for the treatment of manure in different breeding environments and provided a reference for the low-carbon and sustainable development of modern cattle farming.In the future, efforts should be made to further promote the resource utilization of manure from large-scale cattle farms. Scientific and reasonable plans for manure treatment and resource utilization models should be developed in various regions. The quality of the surrounding environment should be monitored, and effective control measures should be taken to promote the healthy development of animal husbandry and lay the foundation for the circular economy and comprehensive utilization of the animal husbandry industry.

Situation Review and Prospect of Dairy Industry in 2023 XIA Jianmin China Dairy    2024, 0 (2): 2-7.   DOI: 10.12377/1671-4393.24.02.01 Abstract （259）      PDF（pc） （3950KB）（196）       Knowledge map    Save Milk production of western dairy developed countries in the past three years did not rise significantly caused by the rise of milk prices, which reflects the maturity of dairy industry. The reduction of export pressure to China also vacated some space for the development of China's milk production. From 2019 to 2023, China's milk production achieved a compound annual growth rate of 7%, far exceeding the average milk consumption growth rate of 4% in the past 15 years, resulting in an oversupply of raw milk and large-scale losses for farms in 2023, and the "cow cycle" has fluctuated significantly. It is expected that the industrial depression period will continue for about 2 years, and the internal industrial structure of the dairy farms will continue to adjust, and small and medium-sized dairy farms will bear the brunt, which requires the industry to pay close attention and work together to overcome the difficulties. In the medium term, the annual growth of 100,000 to 150,000 dairy cattle can meet the growth of milk consumption in China. During the adjustment period, industrial innovation can be made in the aspects of reducing dairy cow, optimizing herd structure, promoting the combination of dairy farming and crop, and optimizing dairy product processing structure.
