Gilt Welfare: Preparing Young Sows for Productive Lives
The welfare of gilts (first-parity sows) during development and introduction to breeding significantly influences long-term sow welfare and farm sustainability.
Key Facts
- Gilt development programs lasting 3-4 months improve reproductive performance and longevity
- Inadequate gilt development is a leading cause of premature sow culling
- Social introduction using small groups reduces aggression injuries
- Body condition at first service critically affects gilt welfare throughout first parity
- Lameness in gilts often originates from developmental problems that were preventable
Welfare Considerations
Gilt welfare is foundational to sow welfare throughout the production cycle. Gilts entering the breeding herd in poor body condition, with unresolved health problems, or inadequately socialized face cumulative welfare deficits. The first parity is particularly demanding—gilts must simultaneously grow, lactate, and recover—creating high welfare risk. Programs that properly develop gilts with appropriate nutrition, health protocols, and social experience produce sows that cope better, live longer, and have better welfare throughout their time in the herd.
What You Can Do
- Implement a dedicated gilt development program of 3-4 months minimum
- Body condition score gilts regularly before and during development
- Use appropriate group introduction protocols to minimize aggression
- Ensure gilts reach adequate weight and condition before first service
- Monitor first-parity sows closely for lameness, mastitis, and condition loss
