Table 2: The contents of \(\alpha\)-tocopherol acetate and selenium in feed and \(\alpha\)-tocopherol and selenium in minced meat (Data from [PERSON] et al. [5]). At 12 weeks of age, the rabbits were transported to the slaughterhouse (Ma.Ge.Ma abattoir, Savignano sul Rubicone, FC, Italy), weighed and electrically stunned (70 V DC, 50 Hz, 5 s). After complete bleeding, skin and viscera were removed, and the hot carcass were weighed and then cooled at 4 \({}^{\circ}\)C for 24 h in a refrigerated cell (Costan Daily TN SP60/4, Costan S.p.A., Belluno, Italy). Ten carcass were randomly selected from each dietary group for analysis. Carcass hygiene was tested, as reported in detail in [PERSON] et al. [26], and the meat was used to prepare hamburgers.
