河南省中小规模蛋鸡场生物安全体系建设研究OA

Henan is one of the most important provinces for livestock and poultry production in China,and the egg laying industry plays a pivotal role in the country,making significant contributions to economic development.Small and medium-sized egg layer farms,defined as those with a stock of 10,000 to 50,000 birds,account for over 80%of the total commercial egg farms in the province.However,biosecurity remains a primary bottleneck restricting their development.The construction of a biosecurity system has become the key to ensuring the sustainable and healthy development of the small and medium-sized egg laying chicken industry.This article focused on small and medium-sized layer farms in Henan Province,relying on the egg laying chicken industry system.Through field interviews and monitoring data,the current situation,existing problems,and improvement measures of their biosecurity system construction are systematically analyzed,and optimization paths are proposed based on the industry development trend.The investigation indicated that small-and medium-sized layer farms still have deficiencies in site layout,input management,personnel management,implementation of disinfection measures,and record keeping.Their biosecurity level therefore needs to be improved through coordinated efforts in management systems,technical measures,and regulatory oversight.
