Energy Requirement Unit for Poultry
Energy requirement of poultry is expressed in terms of:
- GE (Gross Energy)
- DE (Digestible Energy)
- NE (Net Energy)
- ME (Metabolizable Energy) — Correct Answer
Explanation:
Correct Answer: ME (Metabolizable Energy)
Energy requirement of poultry is expressed in terms of Metabolizable Energy (ME), measured in kcal/kg of feed.
Why ME for Poultry?
- Poultry excrete both urine and faeces together through the cloaca as urine-faecal mix — making it impossible to measure faecal and urinary energy losses separately.
- ME = GE − (Faecal energy + Urinary energy)
- Since faecal + urinary are excreted together in poultry, ME is the most practical energy measure.
Energy Measures for Different Species
| Species | Energy Measure Used |
|---|---|
| Poultry | ME (Metabolizable Energy) |
| Pigs | DE (Digestible Energy) |
| Ruminants (cattle, sheep) | ME or NE (Net Energy) |
ME Values from BIS 2007 (Poultry Feed)
- Broiler prestarter: 3000 kcal/kg
- Broiler starter: 3100 kcal/kg
- Broiler finisher: 3200 kcal/kg
- Layer Phase I: 2600 kcal/kg; Layer Phase II: 2400 kcal/kg
