Farm
By Colin Marry
June, 8th 2016 - Dublin
Introduction
• Farm: 850 Sow Unit
• Breed & Finish
• Health Focus
• Health Professional / Pig Producer; 33
• President of Irish Pig Health Society; EPP Ireland Chairman; Former IFA Pig Health Chairman
Farm Health History
• Re-Stocked in 2009
• Vaccinating for PCV2 2010
• Broke with Mycoplasma Pneumonia Dec 2012; vaccinating since
• Gilt & Sow Vaccines: E.Coli; Parvo; Erysipelas
• Negative to date for Ileitis; PRRS; APP; etc
• No In-Feed or Water Antibiotics
Health Management Overview
• Work Closely With Farm Vet
• External Bio-Security – Identify & Prevention
• Internal Bio-Security – Identify & Manage
• Improving the Environment
• Motivating as it will be an increasingly bigger issue with consumers
External Bio-Security
• Rear Own Replacement Gilts (PCV2 route)
• Deliver Dead Stock to Rendering Plant (Mycoplasma route)
• 48 Hours Pig Free
• A.I. Station Who Follow Agreed Protocol (PRRS Testing)
• Water Quality
• Dedicated Lorry
Internal Bio-Security
• Monthly Vet Visits; Walk Through Unit
• Delivery of Dead Pigs to Diagnostic Labs
• Lung Scoring at Factory
• Rope Testing to Monitor Vaccine Efficacy
Internal Bio-Security – Enhanced
• Gent University Work & Biocheck Program
• Teagasc Pig Development Department
• Weighting and measuring impact
• “Showering into a farm is not important if you ignore more important steps; of which there are many.”

Reviewing Internal Biosecurity
• Balance Controls with Management
• Focus on Higher Risk Parts:
- Dead Pigs
- Sick Pigs
- Newborn Pigs
Environment: Reducing Stress at Weaning
• Moved in at 14 Days Post Farrowing
• Sows Weaned at 30 Days
• Piglets Stay in Room Until 95 days of age
• Reduces or eliminates many of the stressors at weaning
Initial Results
• Slightly More Over-Lays.. but
• Less Natural Deaths; Less Intervention
• Growth On a Par
• Sows On Heat as Normal Post-Weaning
• Looking to Sequence Microbiota to Check if it is More Diverse Compared to Traditional System
Future
• “Consumer Confidence is Key to Success” – Prof Patrick Wall
• Demand for Antibiotic Free Meat
• Be Able to Supply that Consistently: Need to Understand Health of Pigs; Diagnostics Vital
