Summary
Small Mexican dairy farms can improve milk supply using multi-criteria programming. Optimizing feed strategies and calving seasons enhances herd nutrition and farm economics.
Area of Science:
- Agricultural Economics
- Animal Science
- Operations Research
Background:
- Mexican dairy production faces a supply deficit, with small-scale farms offering potential to increase output.
- Optimizing resource allocation is crucial for the economic viability of smallholder dairy systems.
Purpose of the Study:
- To evaluate the effectiveness of goal programming and compromise programming in analyzing small-scale Mexican dairy farm systems.
- To identify optimal feeding strategies and calving schedules for improved herd performance and profitability.
Main Methods:
- Development of four ordinary linear programming models with specific objective functions (energy, income, protein, feed minimization).
- Application of goal programming and compromise programming techniques for multi-criteria analysis.
- Integration of forage strategies (alfalfa, ryegrass, corn silage) and calving season rescheduling.
Main Results:
- Both goal programming and compromise programming provided comprehensive insights into dairy system management.
- A forage strategy utilizing alfalfa, ryegrass, and corn silage was identified as adequate for meeting herd nutrient requirements.
- Rescheduling the calving season to the second and third quarters showed economic benefits due to synchronized nutrient demand and forage availability.
Conclusions:
- Multi-criteria programming models are valuable tools for analyzing and optimizing small-scale dairy farm operations.
- Strategic forage selection and calving season management can significantly improve the economic performance and sustainability of Mexican dairy farms.
