概括

这项研究评估了用于紧急猪人口减少的替代A类水性泡 (WBF). 发现四种新的WBF缩剂是有效的,为疾病爆发提供了更多的选择.

科学领域:

兽医医学兽医医学兽医医学
动物科学动物科学
农业工程农业工程

背景情况:

猪业需要高效的大规模紧急人口减少方法.
类A水性泡 (WBF) 是一种可行的减少人数的选择,但依赖单一产品 (WD881) 会带来供应风险.

研究的目的:

调查15种商业上可用的WBF缩剂对于猪人口减少的适用性.
为了比较它们的发泡性能,生理效果和有效性,与已建立的WD881.1相比.

主要方法:

在各种度和压力下评估WBF性能 (填充时间,衰变率).
在短时间暴露期间对小猪的评估生理影响和病变.
在成年猪的实地试验中,使用数据记录器测量了停止移动的时间 (COM).

主要成果:

四种WBF缩剂 (FireIce Polar EcoFoam,Buckeye Platinum,National Foams Knockdown,BioFor N) 在1%度下显示出与WD881相当的性能.
在WBF组之间没有注意到生理效应或病变的显著差异.
所有测试的泡在现场试验中都实现了100%的死亡率,COM的平均时间为151.5秒.

结论:

四种新的,商业上可用的WBF缩剂适用于大规模的猪人口减少.
扩大WBF选项通过减轻疾病爆发期间的供应链漏洞来增强生物安全.

Chemical Agents for Microbial Control

Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...
