Adding Sacha Inchi oil to the diet of laying hens at concentrations of 1.5–4.5% does not change how many eggs they lay, their body weight, or the thickness of their eggshells, the internal quality of...

We analyzed one assertion on Sacha Inchi oil and laying hens, and found no evidence that it changes egg production or egg quality. Specifically, when hens were fed diets containing 1.5% to 4.5% Sacha Inchi oil over 56 days, the number of eggs laid, their body weight, eggshell thickness, egg white quality, and yolk color remained unchanged [1]. This single assertion includes 18.0 supporting points and no refuting data. What we’ve found so far suggests that, under these specific conditions, Sacha Inchi oil does not appear to influence the measurable traits of egg output or appearance. The evidence does not show improvement or decline — just stability. We cannot say whether longer feeding periods, different concentrations, or other hen breeds might produce different results, because no other studies were included in our review. The lack of refuting data doesn’t mean Sacha Inchi oil has a positive effect — it only means that, in this one set of conditions, no negative or positive changes were detected. We don’t know if it helps, harms, or does nothing beyond what was measured. For farmers or backyard flock owners considering Sacha Inchi oil as a feed additive, this suggests it’s unlikely to disrupt laying patterns or egg appearance based on the limited data available. But without more research, it’s not possible to say whether it offers any hidden benefits or risks over time.
