Question

In a normal cow, the Ca content of blood is 2-3 millimol (mM), whereas that of milk is 25-30 mM and that of colostrum is:

• A. 6-7 mM
• B. 62-75 mM
• C. 40-50 mM
• D. 15-30 mM

Hint:

Colostrum: rich in calcium, immunoglobulins.
Calcium content: 40-50 mM.
Higher than mature milk.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Calcium concentration varies in different body fluids.
Colostrum has a different calcium content than mature milk.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the calcium concentration in colostrum.

Step 3: Detailed Explanation:
Blood Ca: 2-3 mM.
Milk Ca: 25-30 mM.
Colostrum Ca: 40-50 mM.
Colostrum has a higher calcium content than mature milk.
Thus, the calcium content of colostrum is 40-50 mM.

Step 4: Final Answer:
The calcium content of colostrum is 40-50 mM.
Hence, the correct option is (C).
