Abstract: An egg rich in nutrients of ?-linolenic acid and DHA, a breeding method of laying hens and a feed additive are provided. Laying hens are fed with a feed additive rich in ?-linolenic acid, after the feed additive are digested and absorbed by the laying hens, a part of the ?-linolenic acid is enriched in the egg yolk, and another part of the ?-linolenic acid is used as a precursor which is metabolized to be DHA by laying hen's biochemical process and thereby partially enriched in the egg yolk. Therefore, the contents of these two nutrients in eggs are greatly increased and reach their respective healthy supply levels, consumers can obtain stable and sufficient nutrition supply from the eggs. The invention can effectively solve a current situation of too low ?-linolenic acid and DHA contents in ordinary eggs while maintaining the nature of eggs as a consumer product.
