Faecal Energy Loss in Pigs
View Complete Answer & Explanation
Question (English)
Faecal energy (FE) loss in the case of pig is approximately what percentage of gross energy intake?
- 5–10%
- 20% ✓ Correct
- 30%
- 40%
Explanation:
Correct Answer: 20%
Faecal energy loss in pigs is 20% of GEi. Pigs are monogastric and are typically fed highly digestible concentrate diets (grains, oil cakes), resulting in relatively lower faecal losses.
Faecal Energy Loss Summary
- Ruminants (roughage): 40–50% of GEi
- Ruminants (concentrate): 20–30% of GEi
- Horse: 35–40% of GEi
- Pig: 20% of GEi
Urinary Energy Losses
- Pig: 2–3% of GEi (lowest — because pigs excrete urea which is water-soluble and excreted readily)
- Ruminants: 4–5% of GEi
Feed Conversion Ratios
Broiler : Pig : Cattle = 2 : 3 : 5 — pig is intermediate efficiency between poultry and cattle.
