Focus of Pearson Square Method
In Pearson square method of ration formulation, a major consideration is given to:
- Protein only — Correct Answer
- Carbohydrate only
- Vitamins & minerals
- All
Explanation:
Correct Answer: Protein only
The Pearson Square method of ration formulation is specifically designed to balance protein (crude protein %) in a ration using two feed ingredients. It solves for the proportions of two feeds needed to achieve a target protein level.
Pearson Square Method — Key Facts
- Major consideration: Crude Protein (CP%) only
- Involves only two feed ingredients (or two groups)
- Simple graphical method using a square diagram
How Pearson Square Works
| Step | Action |
|---|---|
| 1 | Write target CP% in the centre of the square |
| 2 | Write CP% of feed A (top-left) and feed B (bottom-left) |
| 3 | Calculate cross-differences (diagonally) |
| 4 | Results give parts of each feed required |
Limitations
- Only balances protein — does not account for energy, minerals, vitamins, or other nutrients
- Suitable only for two-ingredient mixtures
- More complete methods: Trial and error method, Simultaneous equations, Computer-based linear programming
Why Other Options Are Wrong
- Carbohydrate only → Pearson Square does not balance carbohydrate; it targets protein %
- Vitamins & minerals → not addressed by Pearson Square method
- All → incorrect; Pearson Square specifically and exclusively focuses on protein content
