摘 要
仔猪腹泻是养猪业中常见的疾病之一，严重影响仔猪的生长发育和养殖效益。本研究旨在剖析猪场仔猪腹泻的主要病因，并提出综合防治策略，以降低发病率和经济损失。通过实地调查、实验室检测及数据分析等方法，研究发现仔猪腹泻的病因主要包括病毒性因素（如轮状病毒、猪流行性腹泻病毒）、细菌性感染（如大肠杆菌、沙门氏菌）以及环境应激和饲养管理不当等非传染性因素。此外，母源抗体不足和免疫程序不合理也是导致仔猪易感的重要原因。基于上述结果，本研究提出了包括疫苗接种、抗生素合理使用、改善环境卫生条件及优化饲养管理在内的综合防治措施。研究表明，采取科学的防控手段可显著降低仔猪腹泻的发生率，提高仔猪成活率和生产性能。本研究的创新点在于结合多因素分析，提出系统化的防治方案，为猪场制定针对性防控策略提供了理论依据和技术支持，对促进养猪业健康发展具有重要意义。

Etiological Analysis and Integrated Control of Diarrhea in Piglet Farms
ABSTRACT
Neonatal piglet diarrhea is one of the most common diseases in the swine industry, significantly affecting the growth and development of piglets as well as the economic benefits of farming. This study aims to analyze the primary etiological factors of piglet diarrhea in swine farms and propose comprehensive prevention and control strategies to reduce incidence rates and economic losses. Through field investigations, laboratory tests, and data analysis, it was found that the main causes of piglet diarrhea include viral factors (such as rotavirus and porcine epidemic diarrhea virus), bacterial infections (such as Escherichia coli and Salmonella), and non-infectious factors such as environmental stress and improper husbandry management. Additionally, insufficient maternal antibodies and irrational immunization schedules were identified as critical reasons contributing to the susceptibility of piglets. Based on these findings, this study proposes integrated prevention and control measures, including vaccination, rational use of antibiotics, improvement of environmental hygiene conditions, and optimization of husbandry management practices. The research demonstrates that the implementation of scientific preventive measures can significantly decrease the occurrence of piglet diarrhea, thereby enhancing piglet survival rates and production performance. The innovation of this study lies in its integration of multifactorial analysis to develop a systematic prevention and control plan, providing theoretical support and technical guidance for swine farms to establish targeted prevention strategies. This study holds significant importance for promoting the healthy and sustainable development of the swine industry.
