Question:
Which one of the criteria is commonly used for assessing feed efficiency in laying hens?
Which one of the criteria is commonly used for assessing feed efficiency in laying hens?
Show Hint
Feed Efficiency always involves a ratio of Feed Input to Product Output.
Since none of the listed choices express a biological input-output ratio, "none" is the logical answer.
Since none of the listed choices express a biological input-output ratio, "none" is the logical answer.

- Daily feed intake per hen
- Feed intake in a farm
- Egg income
- none
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Feed efficiency measures how effectively an animal converts feed intake into a marketable food product.
Step 3: Detailed Explanation:
1. In laying hens, feed efficiency is scientifically measured using the Feed Conversion Ratio (FCR).
2. FCR in layers is expressed as:
- Kilograms of feed consumed per kilogram of egg mass produced, or
- Kilograms of feed consumed per dozen eggs produced.
3. Let us evaluate the options:
- Daily feed intake per hen is simply a measure of feed consumption, not efficiency.
- Feed intake in a farm is a measure of total volume consumed.
- Egg income is a financial parameter, not a biological feed efficiency metric.
4. Since none of the options list FCR (feed per kg egg mass or feed per dozen eggs), the correct choice is "none".
Step 4: Final Answer
The correct option is (D).
