The effect of dried tomato pomace (DTP) was tested on lamb performances, meat fatty acids and oxidative stability. For 36 days, one group of lambs (n = 7; CON) was fed a commercial concentrate, while the other group (n = 7; DTP) received DTP in addition to CON diet. The administration of DTP reduced (P <.05) concentrate intake, with no effect on animal performances. The DTP treatment tended to increase total polyunsaturated fatty acids (PUFA; P =.075), PUFA n-6 (P =.071), α-linolenic acid (P =.096) and increased linoleic acid (P <.05), γ-tocopherol (P <.001) and retinol (P <.001) in meat. In raw meat, DTP treatment increased L* (P =.059), b* (P <.05), C* (P =.052) and H* (P <.05) values compared to CON, while lipid oxidation was not affected. In meat homogenates incubated with pro-oxidants, DTP tended to reduce 2-thiobarbituric acid reactive substances (TBARS; P =.088). Therefore, DTP supplementation decreased the consumption of commercial concentrate without detrimental effects on animal performances and meat quality traits.
