Blood meal’s origin is typically from which source?

• A. Slaughterhouses.
• B. Crop residues.
• C. Forest products.
• D. Grazed pasture.

Answer: (A)

Blood meal is a high-protein feed ingredient made from the blood collected during animal slaughter and processing. After animals are slaughtered, the collected blood is coagulated, dried, and ground into a meal that can be added to feeds. This makes slaughterhouses the typical origin of blood meal, since the product is a byproduct of meat production.

Crop residues come from plant material left after harvest and are used for energy or fiber, not blood-derived protein. Forest products refer to wood or wood byproducts, which aren’t sources of animal blood. Grazed pasture is fresh plant forage rather than a processing byproduct, so it doesn’t provide blood-derived protein.
