When to use

  • Tracking quarantine timelines for newly purchased or transferred pigs
  • Managing multiple quarantine groups from different sources
  • Documenting biosecurity compliance for veterinary or regulatory audits
  • Planning introduction timing of replacement gilts or boars

Do not use for

  • As a substitute for daily veterinary health observations — the countdown is a minimum, not a guarantee of health
  • For pigs being quarantined due to active disease — treatment protocols have different timelines
  • As the only biosecurity measure — always combine with serology and physical isolation

Physical isolation is non-negotiable

Quarantine pens must be in a separate building or at least 500 ft from production animals. Airborne pathogens (PRRS) can travel between adjacent buildings. A countdown timer is meaningless without true physical separation.

Never share equipment between quarantine and production

Needles, boots, coveralls, chutes, and nets used in quarantine must never enter the production barn. Contaminated equipment bypasses the entire quarantine period in a single exposure.

21 days is the minimum, not the gold standard

AASV and most veterinary biosecurity protocols recommend 30–60 days for replacement animals, especially for PRRS-negative herds. Extend the timer to match your herd health objectives.

Restart the clock on any health event

If any animal in the quarantine group becomes ill, restart the quarantine period from the last day of treatment. Partial quarantine after a health event provides false security.

Method

Days elapsed calculated from arrival date to today (client clock, no server calls). Clearance date = Arrival Date + Quarantine Days. Progress bar shows (Elapsed / Total) ×\times 100%. All calculation is client-side — no data leaves your browser. Default 21-day period per AASV minimum guidelines.

Why Quarantine is the #1 Swine Biosecurity Practice

Quarantine is the most effective single intervention for preventing the introduction of new pathogens into a swine herd. New pigs — even those sourced from certified high-health suppliers — may carry subclinical infections with PRRS, Mycoplasma hyopneumoniae, Streptococcus suis, or Lawsonia intracellularis that only manifest under the stress of transport and new environments.

Standard quarantine requirements: - Duration: 21 days minimum; 30–60 days for PRRS-negative or SPF herds - Location: Separate building or airspace; minimum 500 ft from production barn in outdoor settings - Equipment: Dedicated boots, coveralls, needles, and handling tools — never shared with production animals - Ventilation: Separate air handling; no shared exhaust fans
What quarantine detects: Most common swine pathogens have incubation periods of 7–21 days. A 21-day quarantine catches the majority of acute infections. Slower-developing conditions (e.g., ileitis, enzootic pneumonia) may require the full 30-day window.

Integrating Serology with Quarantine

Quarantine time alone is insufficient for a rigorous biosecurity program. Pair the countdown with a serology protocol:

1. Day 0 (Arrival): PCR for PRRS and PCV2; baseline serology panel 2. Day 21–30: Repeat ELISA for PRRS antibodies; if seropositive and your herd is PRRS-negative, do not move animals 3. Day 30–60 (PRRS-negative herds): Second ELISA; if still seronegative and antigen-negative, proceed with integration

Work with your veterinarian to design a testing protocol based on your herd's target health status and the risk profile of the source population.
