What is the crude protein content range of blood meal after processing?

• A. 85% to 90%
• B. 60% to 65%
• C. 70% to 75%
• D. 95% to 100%

Answer: (A)

Blood meal is a highly concentrated protein source created by drying and processing blood collected during slaughter, which leaves a product rich in blood proteins. After processing, the crude protein content on a dry matter basis is typically around 85 to 90 percent. This high level reflects the dominance of protein from blood and the relatively small amount of other constituents that remain, such as minerals (ash) and trace fats. Values in the 60s or 70s would underestimate the protein contribution of blood proteins, while 95–100 percent would be unrealistically high because some non-protein material always remains. On an as-fed basis, CP would be slightly lower depending on moisture, but the standard dried-blood-meal specification sits in the 85–90 percent range.
