Frequently Asked Questions
What is the Pearson Square Method?
The Pearson Square is a simplified, mathematical method used to balance one nutrient (typically protein) using two ingredients. It's been used by farmers for decades because it requires only basic arithmetic. You place your target protein in the center and your two ingredient protein values on the left corners. The differences are calculated diagonally and give you the mixing ratio.
Why do I need to balance protein in feed?
Balancing protein is crucial for two reasons: cost efficiency and growth optimization. Over-feeding protein wastes money (protein sources like soybean meal are expensive), while under-feeding slows growth and reduces productivity. Different animals at different stages (calves, growing cattle, lactating cows) need different protein levels. By balancing correctly, you provide exactly what your animals need without overspending.
Can I mix more than 2 ingredients?
The Pearson Square method is designed for balancing two ingredients only. For complex feed formulations with 3 or more ingredients, or when you need to balance multiple nutrients (energy, minerals, vitamins) simultaneously, you'll need linear programming or specialized software.
💡 Pro Tip: For advanced feed formulation with multiple ingredients and nutrients, try the complete Feed Module in the Herdly Farmer App. It handles complex calculations and tracks your feed inventory automatically.
What protein level should I target?
| Animal Type | Target Protein |
|---|---|
| Young calves (0-3 months) | 18-20% |
| Growing cattle (3-12 months) | 14-16% |
| Feedlot/Fattening cattle | 12-14% |
| Lactating dairy cows | 16-18% |
| Goats (growing kids) | 14-16% |
| Meat goats (finishing) | 12-14% |
* These are general guidelines. Consult with a local nutritionist for specific recommendations based on your animals and available feed ingredients.
