  1. Fatty acid composition in oils from thermal treatment of hens with viscera, head and feathers (HwT) and hens without viscera, head and feathers (Hw/oT). The fatty acids are named by the ω-system, were Cx:y ωz denotes a fatty acid with a chain length of x carbon atoms containing y numbers of double bonds. z denotes the position of the first double bond, counting from the methyl end of the carbon chain. Content of the individual fatty acids are given as % of total fatty acids (\( \overline{\mathrm{x}} \) ± SD, n = 2)
