Production method of lycopene-containing poultry eggs, spawning poultry feed, and lycopene-containing poultry eggs

摘要

PROBLEM TO BE SOLVED: To provide a poultry egg containing lycopene capable of efficiently ingesting lycopene. SOLUTION: The lycopene-containing poultry egg has 80% by mass or more of cis-type lycopene when the whole lycopene contained in the yolk is 100% by mass. In addition, lycopene-containing poultry eggs are produced by the following cis-type lycopene-enriched feed group in which the lycopene content of egg yolk is more than twice that of the control poultry eggs produced by the following control groups. Control group Control poultry eggs were produced by feeding spawning poultry with a feed containing a predetermined amount of lycopene and having a cis-type lycopene content of 5.5% by mass or less when the total content of lycopene was 100% by mass. Cis-type lycopene-enriched feed group A feed containing the same amount of lycopene as the feed used in the control group and having a cis-type lycopene content of 35% by mass or more when the total content of lycopene is 100% by mass is fed to the spawning poultry to contain lycopene. Produced eggs. [Selection diagram] Fig. 4
