Eighty New Zealand White rabbits, age 55 days, half male and half female, were randomly assigned to one of four diets in a 2 x 2 x 2 factorial arrangement.

Abstract
Eighty New Zealand White rabbits, age 55 days, half male and half female, were randomly assigned to one of four diets in a 2 x 2 x 2 factorial arrangement. The diets contained 0% or 0.5% CLA, and 60 or 240 mg/kg alpha-Tocopheryl acetate. Forty-eight rabbits were slaughtered at age 92 days. Growth performances and carcass weight were higher (P < 0.05) in 240 mg/kg of alpha-tocopheryl acetate-fed rabbits. Fat and CLA isomers content of Longissimus Lumborum (LL) muscle was higher (P < 0.05) in CLA-fed rabbits than control. Fatty acid composition of LL muscle was modified (P < 0.05) and oxidative stability was increased (P < 0.001) by both dietary treatments. CLA increased (P < 0.05) triglyceride, total cholesterol and glucose levels in plasma. Adipocytes in interscapular and perirenal fat in the 240 mg/kg alpha-tocopheryl acetate and 0.5% CLA groups were larger in size but lesser in number than in 60 mg/kg alpha-tocopheryl acetate and no CLA rabbit (P < 0.01).File | Dimensione | Formato | |
