Linoleic Acid Requirement for Maximum Egg Size in Laying Hen
Linoleic acid requirement for a laying hen for maximum egg size should be:
- 1% — Correct Answer
- 2%
- 3%
- 5%
Explanation:
Correct Answer: 1%
The linoleic acid (LA) requirement for a laying hen for maximum egg size is 1% of the diet. This is also confirmed by the BIS (Bureau of Indian Standards) 2007 standards for layer feed.
Linoleic Acid in Poultry Nutrition
- Linoleic acid (18:2, ω-6) is the essential fatty acid for poultry.
- It is essential for: normal growth, feathering, egg production, and maximum egg size.
- The BIS 2007 standard specifies: minimum 1.0 g/100 g feed (= 1%) for all layer phases.
- Deficiency leads to: reduced egg size, poor feathering, growth depression.
Essential Fatty Acid and Essential Amino Acid for Poultry
- Essential fatty acid: Linoleic acid
- Essential amino acid: Glycine (most critical for poultry; unlike mammals where it is non-essential)
Why Other Options Are Wrong
- 2%, 3%, 5% → exceed the established minimum requirement; the BIS-specified minimum is 1%, which is sufficient for maximum egg size.
