Poultry industry research concludes VSD takes at least 3.75 hours to kill chickens and adding additional heat (VSD+) takes a minimum 2 hours and does not meet the standard of 100% lethality. “An alternative depopulation method with potential for use in the egg industry is ventilation shutdown (VSD), which uses a combination of increasing heat and carbon dioxide (CO2) levels to promote death by hyperthermia and hypoxia. This proof-of concept study was designed to evaluate the effectiveness of VSD, VSD with supplemental heat (VSDH), and VSD with CO2 (VSDCO2) as alternative mass depopulation methods in a multilevel caged system. Assessment parameters included ambient and core body temperatures, time to death, and survivability. Time to death for VSD, VSDH, and VSDCO2 were 3.75, 2, and 1.5 h, respectively. Survivability in VSD did not meet the flock depopulation standard of 100% lethality.” Evaluation of Ventilation Shutdown in a Multi-level Caged System 2018 Journal of Applied Poultry Research
