Fermented Animal Waste
Anaerobically fermented animal waste with the help of lactic acid producing bacteria is known as:
- Haylage
- Soilage
- Wastelage — Correct Answer
- None
Explanation:
Correct Answer: Wastelage
Wastelage is an innovative method of anaerobically fermenting animal waste (poultry droppings, poultry litter, swine excreta, bovine dung) using lactic acid-producing bacteria to produce a preserved, palatable feed.
Types of Ensiled/Fermented Products
| Product | Raw Material | Process |
|---|---|---|
| Silage | Green fodder | Anaerobic fermentation |
| Haylage | Grass/legume (meant for hay) | Ensiling at 45–55% moisture |
| Wastelage | Animal waste (poultry droppings, swine excreta, bovine dung) | Anaerobic fermentation with lactic acid bacteria |
| Soilage | Green fodder | Cut and fed fresh (no fermentation) |
Wastelage — Key Facts
- Recycles animal waste into usable feed value
- Reduces environmental pollution from manure
- Used to supplement ruminant diets with recycled nitrogen
- Process requires appropriate moisture and compaction to ensure anaerobic conditions
Why Other Options Are Wrong
- Haylage → ensiled grass/legume meant for hay; raw material is green plant, not animal waste
- Soilage → fresh-cut green fodder fed directly; no fermentation, not waste-based
- None → incorrect; Wastelage is the specific defined term for fermented animal waste
