牛副流感病毒感染的防控挑战与对策分析

摘  要
本文概述了牛副流感病毒的相关特点、临床症状、防控难点及综合防控对策。牛副流感病毒是一种具有特定结构特点的病毒，主要通过特定途径传播。感染该病毒后，牛只常表现出淋巴结肿大、精神沉郁及眼结膜发炎等临床症状。然而，牛副流感病毒的防控面临多重难点，包括环境卫生不达标、饲养密度过高以及病毒传播途径广泛等问题。为有效应对这些挑战，本文提出了综合防控对策，包括改善养殖环境的通风条件以减少病毒滋生，合理控制饲养密度以降低感染风险，以及严格执行隔离制度以防止病毒扩散。本研究旨在为牛副流感病毒的防控提供科学依据，保障牛只健康，促进畜牧业稳定发展，减少经济损失，提高养殖效益。

CHALLENGE AND COUNTERMEASURES OF BOVINE PARAINFLUENZA VIRUS INFECTION

ABSTRACT
This paper summarizes the related characteristics, clinical symptoms, prevention and control difficulties and the use of bovine parainfluenza virus with comprehensive prevention and control countermeasures. Bovine parainfluenza virus is a virus with specific structural characteristics, mainly transmitted through specific routes. After infection with the virus, cattle often show clinical symptoms such as lymph node enlargement, mental depression, and inflammation of the eye conjunctiva. However, the prevention and control of bovine parainfluenza virus is faced with multiple difficulties, including substandard environmental hygiene, high feeding density and extensive transmission routes of the virus. To effectively respond to these challenges, this paper proposes comprehensive prevention and control countermeasures, including improving the ventilation conditions of the breeding environment to reduce the breeding of the virus, rational control of the feeding density to reduce the risk of infection, and strict implementation of the isolation system to prevent the spread of the virus. This study aims to provide a scientific basis for the prevention and control of bovine parainfluenza virus, guarantee the health of cattle, promote the stable development of animal husbandry, reduce economic losses and improve breeding benefits.

KEY WORDS：Bovine accessory influenza; prevention and control challenges; monitoring and early warning
