Study on Aeromonas hydrophila disease in European eel
In recent years, large-scale intensive farming of European eel has been increasing in China. However, with the expansion of farming scale and the continuous increase in farming density, various problems affecting the survival rate of European eel have also been increasing, and the fulminant infectious disease of European eel caused by Aeromonas hydrophila as the pathogen is one of the prominent problems. This paper conducts a series of preliminary studies on the physiological and biochemical characteristics, pathogenic factors, and pathogenic conditions of Aeromonas hydrophila, aiming to provide a strong theoretical basis for the prevention and control of fulminant infectious diseases in European eel, and to better promote the development of the European eel farming industry toward stronger

Research and Analysis of High-Efficiency Lotus Root Cultivation Models: A Case Study of Lotus Fields in Caidian District
Lotus root is one of the pillar agricultural industries of Caidian District, Wuhan City. In 2006, the planting area was 10,000 hectares, the total output was 200,000 t, and the total output value was 320 million yuan, accounting for 18.2% of the district's total agricultural output value. In order to improve the economic benefits of lotus fields, Caidian District promoted several high-efficiency lotus field cultivation models and achieved good results. In 2006, the promoted area of the models in the district reached 7,730 hectares, accounting for 77.3% of the district's lotus root planting area.

Study on Immunization Methods against Swine Trichinellosis and Biochemical Characteristics of Trichinella Antigens
1. Biochemical characteristics of Trichinella antigens: For the first time, advanced techniques including sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), isoelectric focusing (IEF), two-dimensional electrophoresis and enzyme-linked immunoelectrotransfer blot (EITB) were applied to analyze 4 types of Trichinella antigens. The analysis showed that the soluble antigen of muscle larvae contains at least glycoproteins, lipoproteins, glycolipoproteins, simple proteins, polysaccharides and esterase isozymes. Two-dimensional electrophoresis revealed 122 polypeptide spots, most of which were acidic polypeptides with molecular weights below 67 KD.

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
