Question

What are the normal levels of urea nitrogen and creatinine in blood of a healthy cattle?

• A. 28-35 mg/dL & 3-4 mg/dL, respectively.
• B. 50-60 mg/dL & 4-5 mg/dL, respectively.
• C. 25-50 mg/dL & 3-4 mg/dL, respectively.
• D. 6-27 mg/dL & 1-2 mg/dL, respectively.

Hint:

Always remember the baseline ranges for cattle:
- BUN: 6-27 mg/dL (lower than dogs/cats due to rumen recycling).
- Creatinine: 1-2 mg/dL.
These values are much lower than the high levels listed in options (A), (B), and (C), which would indicate severe renal failure.

Answer 1

The Correct Option is D
