The nutrients contained in the raw egg, liver and outer skin of silky and white leghorn were analzyed.
The amount of proteins, phosholipids, α-tocopherol and retinol in the raw egg of silky were high compared to white leghorn.
However, the concentration of cholesterol was lower in silky than white leghorn.
Adult male rats were fed a cholesterol diet with 1% egg oil and 5% dried outer skin. After 4 weeks of feeding, serum total cholesterol concentration was significantly lower in rats fed silky egg oil than in those fed white leghorn egg oil.It seems that the ingredient which affects lipid metabolism does not exist in the outer skin of the silky.
There was a higher amount of IgG in serum of the outer skin of silky group compared to outer skin of white leghon group.
The amount of total proteins and RAN in liver were higher in ratsfed with dried outer skin of the silky. Moreover, the GOT and GPT activity in the liver were found to be higher in the case of outer skin of silky group than the outer skin of white leghon group.
We suggest the possible presence of a component in the outer skin of silky which promotes the activation of the liver function.
