Feed4Profit
Formulate diets, compare programs, and connect feed decisions to profit — all in one place.
Designed by engineering students for nutritionists, producers, and research teams who want quick, clear answers to a simple question: “What happens to margin if we change this feed program?”
All calculations happen on your device. Diet libraries are saved and loaded via JSON files you control.
Baseline vs. new strategies under current prices.
Starter, grower, finisher — each with its own constraints.
Per pig and per group for clear economic decisions.
What can you do with Feed4Profit?
Build diet libraries
Create a library of diets with ingredients, prices, and detailed nutrient profiles. Each ingredient can carry phase-specific nutrient assumptions and min/max bounds.
- Multiple diets per library.
- Per-ingredient nutrients (e.g. Dry Matter, Energy, Amino acids).
- Optional min/max constraints for each nutrient and ingredient.
Compare feed programs
Assemble diets into programs and see how different strategies impact performance and economics under the same market conditions.
- Program 1 vs Program 2, side-by-side.
- Flexible phases with min/max days or bodyweight ranges.
- Revenue, feed cost, and margin summaries.
Model performance over time
Use performance assumptions to project bodyweight and feed usage over time, then overlay different programs on the same graph.
- Bodyweight vs. time curves.
- Feed usage vs. time per program.
- Visualize “what if” scenarios before changing the barn.
Your workflow in three steps
1. Define diets
Start by describing your diets in the Diet Library:
- Ingredients, inclusion percentages, and price per ton.
- Per-ingredient nutrient profiles with value, min, and max.
- Export and import libraries as JSON files.
2. Build programs
Combine diets into full programs with clear phase structure:
- Assign diets to phases (starter, grower, finisher, etc.).
- Set min/max bounds for each phase (days or bodyweight).
- Specify pig numbers, starting weights, and target market weights.
3. Compare outcomes
Use Program Comparison and Performance Modeling to see:
- Differences in feed cost per pig and per group.
- Revenue shifts under different lean hog prices.
- Margin impact when you adjust a single diet or phase.
Who is Feed4Profit for?
- Swine nutritionists testing alternative ingredients and formulas.
- Producers evaluating program changes before implementing them in barns.
- Students and researchers exploring diet economics and growth models.
It’s meant to be practical: start with simple assumptions and grow into more complex models as your data and questions evolve.
What’s under the hood?
Feed4Profit is built around a linear programming mindset: diets and programs are described with constraints, and the goal is to understand how those constraints shape costs and performance.
- Ingredient-level constraints (min/max inclusion).
- Nutrient-level constraints (min/max targets per ingredient and diet).
- Hooks for optimization models (cost minimization or margin maximization).
As the project grows, these same structures can feed directly into solvers and more advanced performance models.
