Question

The calcium to phosphorus ratio in the ration of laying hens should be:

• A. 10:1
• B. 2:1
• C. 15:1
• D. 9:1

Hint:

Laying hens: Ca:P = 10:1.
High calcium for eggshell.
Other poultry: lower ratios.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Calcium and phosphorus are important minerals.
Their ratio is critical for egg production.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the recommended Ca:P ratio.

Step 3: Detailed Explanation:
For laying hens, the calcium to phosphorus ratio should be around 10:1.
This is because eggshell formation requires high calcium.
Other ratios are not suitable for layers.
Thus, the ratio is 10:1.

Step 4: Final Answer:
The Ca:P ratio in laying hens should be 10:1.
Hence, the correct option is (A).
