Biological Value of Microbial Protein
Biological value of microbial protein is:
- 60
- 70
- 80 — Correct Answer
- 90
Explanation:
Correct Answer: 80
Ruminal microbes (bacteria and protozoa) are continuously washed out of the rumen and digested in the abomasum and small intestine, providing the host with Microbial Crude Protein (MCP). MCP has a Biological Value (BV) of approximately 80, making it a high-quality protein source with a good essential amino acid profile for the host animal.
Protein Evaluation Methods
| Method | Used for | Definition |
|---|---|---|
| Biological Value (BV) | Non-ruminants | % of absorbed nitrogen retained in body |
| Protein Efficiency Ratio (PER) | Non-ruminants | Weight gain per gram protein consumed |
| DCP estimation by digestion trial | Ruminants | Digestible Crude Protein from faecal collection |
| Nitrogen balance experiment | Ruminants | N intake − N excreted |
VFA Contribution to Ruminant Energy
- VFAs provide 70% of ruminant energy needs
- Acetate:Propionate:Butyrate = 65:20:10
