Q.58
Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : Enrichment of the omega-3 fatty acid content of yolk using fish oils or fish meals has been investigated with
success by researchers.
Reason (R) : The fatty acid composition of yolk lipid is influenced by the type of fat in the diets of the hens.
In light of the above statements, choose the correct answer from the options given below.
- Production of Omega-3 Enriched Designer Eggs:
- Avian lipid metabolism is unique because unlike ruminants (where rumen biohydrogenation saturates dietary lipids), laying hens directly absorb dietary fatty acids and incorporate them intact into hepatic very-low-density lipoproteins (VLDL-yolk).
- Dietary inclusion of marine fish oils, fish meal, or microalgal biomass rich in long-chain polyunsaturated fatty acids (EPA, DHA) directly and markedly elevates the $\omega-3$ fatty acid content of egg yolk lipids.
- nalysis:
- Both (A) and (R) are true, and (R) provides the physiological explanation for (A). Hence, Option 1 is correct.
