[PorkCHOP: an economic microcomputer replacement model for sows]
Tijdschrift Voor Diergeneeskunde
|November 1, 1986
Summary
PorkCHOP is a computer model that helps swine farmers make better culling decisions. It calculates an economic index to guide sow replacement, optimizing herd profitability.
Area of Science:
- Animal Science
- Agricultural Economics
- Computational Biology
Context:
- Swine breeding herds require efficient management for economic viability.
- Culling decisions significantly impact herd productivity and profitability.
- Existing methods for sow culling may not fully incorporate economic factors.
Purpose:
- To develop a user-friendly computer model for economically sound culling decisions in swine breeding herds.
- To quantify the economic benefits of improved sow herd life and reproductive efficiency.
- To provide a culling guide index for individual sows and determine optimal re-breeding strategies.
Summary:
- The PorkCHOP (Swine Herd Optimization and Replacement) model, developed on a microcomputer spreadsheet, assists farmers and veterinarians in making culling decisions.
- It quantifies benefits of extended sow herd life and reduced farrowing intervals, calculating a 'Retention Pay-Off' economic index.
- The model also determines maximum allowable services for sows failing to conceive, with adjustable parameters for specific herd economics.
Impact:
- Enables data-driven, economically optimized culling strategies in swine production.
- Improves overall herd efficiency and profitability through better sow management.
- Provides a valuable tool for livestock specialists to enhance decision-making in breeding herds.
