Feed Conversion Ratio (FCR) for Broiler Chicken
Feed conversion ratio (FCR) for a broiler chicken should be:
- 1.2
- 1.4
- 1.8
- 2 — Correct Answer
Explanation:
Correct Answer: 2
The standard Feed Conversion Ratio (FCR) for broiler chicken is 2, meaning 2 kg of feed is required to produce 1 kg of live body weight.
Understanding FCR
- FCR = Total Feed Consumed ÷ Total Live Weight Gain
- A lower FCR is better (fewer kg of feed per kg of meat produced).
- Broiler FCR of 2 means: total feed (3.8 kg) ÷ live weight gain (~1.9 kg) ≈ 2.
Factors Affecting FCR
- Feed quality (energy and amino acid density)
- Health status (disease reduces FCR efficiency)
- Genetics (commercial broiler strains have been selectively bred for better FCR)
- Environmental temperature (cold = more energy for heat, worse FCR; hot = reduced feed intake)
FCR in Context
| Species | Approximate FCR |
|---|---|
| Broiler chicken | 2.0 |
| Pig | 3.0 |
| Beef cattle | 6–8 |
