Growth, feed efficiency and polyunsaturated fatty acid profile (omega-6 and omega-3) were evaluated in fattening rabbits fed diets containing two novel products derived from the flaxseed oil production. A total of 400 rabbits were distributed among the five experimental diets (CTL: control, PL-O: mixture of high fat flaxseed chaff and wheat flour (70:30); PL-E: PL + Vitamin E, HL-O: high fat extruded flaxseed meal, HL-E: HL + Vitamin E) at 36 days of age. At 71 days of age, 20 animals/diet were euthanized to quantify the fatty acid profile in the longissimus dorsi muscle. Growth (≈ 40 g/rabbit/day), feed consumption (≈ 129 g/day), and the health risk index (morbidity + mortality ≈ 44.5%) were similar among the five diets. The proportion of omega-6 polyunsaturated fatty acids was higher in the CTL diet with respect to the other diets (≈ 2.0 points). The diets containing PL and HL had a fatty acid profile with a higher percentage of omega-3 polyunsaturated fatty acids (≈ 3.7 points) relative to the CTL diet, resulting in a higher omega-6/omega-3 ratio in the CTL diet relative to the other diets (≈ 4.3 units).
