In this episode of Pharmgate's Swine Health Hotline, Kasey Brown sits down with veterinarian and water-line expert Gabi Doughan to unravel how water line systems impact pig health, performance and biosecurity. Here’s what you need to know:
Key Takeaways
1. Why Water Flow & Design Matter
- Water flow rates should match pig age and production stage.
- The difference in water supply needs between nursery pigs and lactating sows is significant — system design must adapt!
- Watch out: If all pig waterers are running simultaneously, barns with smaller pipes may not get adequate water to pigs furthest from the supply.
2. Water Medicator 101
- Medicated water is critical since sick pigs often stop eating but still drink.
- There are three main types:
- Piston Pumps (affordable, easy install, but prone to scale buildup)
- Diaphragm Pumps (slightly more expensive, fewer mechanical parts)
- Flow-Activated Pumps (most precise, best for clean dosing, but higher cost and learning curve)
- Always calibrate your medicator — even a new one straight out of the box!
3. Keep it Clean: Water Line & Medicator Maintenance
- Clean waterlines and medicators = healthier pigs and fewer dosing errors.
- Regular cleaning tackles mineral buildup and biofilm (those slimy bacterial communities that protect germs from disinfectants).
- Terminal deep cleaning and routine low-dose disinfectants are both important, depending on your barn’s downtime and design.
- Never run oral vaccines or medications through lines while water disinfectants are active — they can interact unpredictably!
4. Diagnostics & Monitoring
- Water quality checks: Test at least once or twice a year, ideally between each turn.
- Test both at the well and in-barn to spot where quality changes.
- Monitor for signs of hard water, pH imbalances and bacterial contamination.
- Regularly check and maintain medicators — replace O-rings, run calibrations, and keep your investment working as it should.
