Blood Meal — Amino Acid Content

Blood meal is a rich source of:

Correct Answer: Lysine

Blood meal is an exceptionally rich source of Lysine — one of the most important essential amino acids often deficient in cereal/grain-based diets.

Blood Meal Facts

• Crude Protein: ~80% — one of the highest protein feed ingredients
• Rich in: Lysine (especially), Isoleucine is present but relatively low
• Conversion ratio: 5:1 (5 kg raw blood → 1 kg blood meal)
• Used as: Protein supplement in livestock and poultry feed

Why Lysine Matters

Lysine is the first limiting amino acid in maize/corn-based diets. Blood meal supplementation effectively corrects this deficiency. Lysine is critical for muscle protein synthesis, calcium absorption, and immune function.
