ABSTRACT The objectives of current study were to evaluate the effect of botanical extracts as antioxidants on amino - and fatty acids profile of broiler meat. In total, 200 one-day-old broiler chicks were divided according to a completely randomized design into eight dietary treatments with five replicates of five chicks each. Dietary treatments were: A - positive control (PC) with antibiotics and synthetic antioxidants, B - negative control (NC), C - NC+Trigonellafoenum-graecum, D -NC+Nigella sativa seed, E -NC+Violaodorata, F -NC+Trachyspermumammi, G -PC+Trachyspermumammi+Trigonellafoenum-graecum+Violaodorata, and H -NC+ Trachyspermumammi, Trigonellafoenum-graecum and Viola odorata. Meat amino - and fatty acid contents were analyzed after slaughter at 35 days of age. Data were submitted to one-way analysis of variance and means were compared by Duncan’s Multiple Range test. The levels of histidine, isoleucine, leucine, lysine and threonine were significantly higher (p≤0.05) in the H, F, E, H and F groups respectively. Arginine, tryptophan, valine, methionine, and phenylalanine were significantly higher (p≤0.05) in the C, F, E, G and H groups. Total essential amino acid levels were highest (40.36%) in C group (p≤0.05). The meat of H broilers presented significantly higher (p≤0.05) unsaturated fatty acids (54.8%) and omega-3 contents (2.77%) and the lowest saturated fatty acid content (44.8%). Group F present the highest linoleic acid and omega-6 levels and group H the highest (p≤0.05) arachidonic and eicosapentaenoic acid (EPA) contents. It was concluded that botanical extracts aid health-beneficial meat production and the simultaneous inclusion of Trachyspermumammi, Trigonellafoenum-graecum, and Viola odorata in broiler diets is a more suitable option than the other dietary regimes.
