This week, Dr. Tyler Bauman, director of health at the Maschhoffs, takes us behind the scenes of a real finishing‑barn problem and the data‑driven discovery it sparked. Through field comparisons of half‑ vs. full‑dose PRRS vaccinations, the team uncovered a meaningful impact: a 3.5% drop in mortality with the full dose. 

He and host Kasey Brown discuss these key takeaways: 

• The Power of Data in Tackling PRRS: [00:02:10]
  Dr. Bauman describes how collecting, analyzing and acting on field data allowed his team to justify changes and demonstrate real ROI to their operational leaders.
• Full Dose vs. Half Dose: What the Numbers Say: [00:10:01]
  Through extensive comparisons, the team found a game-changer for barn health.
• Adapting Vaccine Timing and Protocols: [00:10:12]
  The investigation grew beyond mere dosing amounts, with experiments around timing to optimize protocols for different barn scenarios.
• Real-Time Testing and Surveillance: [00:08:48]
  Aggressive, routine testing enabled faster detection and response to PRRS breaks, leading to better overall outcomes and earlier interventions.
• Collaboration, Communication, and Continuous Improvement: [00:23:57]
  Success hinged on buy-in at every level. He emphasized transparent data sharing and proactive communication, which led to broader adoption and improved barn performance.
• Managing Expectations & Setting Goals: [00:26:45]
  Managing PRRS isn’t about eliminating all risk — it's about setting realistic goals, managing expectations, and consistently refining your strategy and response plan.

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.
