The Effect of Feeding Laying Hens with Nonindustrial Hemp Seed on the Fatty Acid Profile, Cholesterol Level, and Tocopherol Composition of Egg Yolk

Table 10

Three main components explain more than 64.25% of the total information on fatty acid profile, cholesterol content, and tocopherol composition during the experimental period.
