80% of disease comes in either the front door or the back door. A producer controls this through use of adequate quarantines (front door) and truck sanitation/disinfection or load out management (back door).
Focus on Gilt Preparation
Start feeding gilts for production when they reach 150-180 pounds:
- Physical Appearance– Gilt conformation and physical characteristics are the most important selection criteria when populating the pool.
- Age at Puberty – Studies have shown that early onset of estrous will yield a sow who lasts longer in the herd.
- Boar Exposure – Exposure to the boar is the single most important factor to cause the gilt to achieve puberty.
- Number of Services- Gilts typically express estrus for a shorter length of time, sometimes 24-36 hours less than a sow.
