Effect of oil blends with near equal increases in 18 carbon n-3 and n-6 fatty acids on fatty acid profile of eggs

Randomized Controlled Trial

2026 Jan

The study found that hens fed stearidonic acid had higher levels of a key fat-making enzyme in their liver compared to those fed other fats, which supports the idea that this fat boosts the enzyme.

Feeding hens a certain type of fat called stearidonic acid helps their bodies make more healthy omega-3s in egg yolks—43% better than another fat called ALA—because it’s easier for their bodies to process.

If you feed laying hens oil rich in a fat called SDA, their eggs end up with way more of the good omega-3 fats—like EPA, DPA, and DHA—compared to feeding them another plant-based omega-3 oil. This happens because SDA skips a slow step in the hen’s body that usually holds back omega-3 production.

Feeding hens a special fat called gamma-linolenic acid (GLA) boosts certain healthy fats in their eggs more than another fat called linoleic acid (LA), and it might skip a slow step in the process — meaning more of the good stuff ends up in the yolk.

Feeding hens a special fat called gamma-linolenic acid (GLA) helps their bodies make more healthy fats for the egg yolk—16.7% better than another fat called linoleic acid—because GLA skips a slow step in the process.
