The study evaluated the effects of nucleotide dietary supplementation on the physical and nutritional characteristics of the pectoralis major muscle of male broiler chickens (n = 60,000), divided into two homogeneous groups: control (C) and nucleotides (N). The animals, from the birth (24 h of age) to the slaughtering age (52 days), received the same diet, supplemented (N) or not (C) with 0.1% of a nucleotide pool. Physical and nutritional characteristics of the pectoralis major muscle were determined after slaughtering on a sample of 130 animals per group, randomly selected. The meat of the N group showed significantly higher redness and Hue values, lower shear force values, higher lipid and ash percentages and iron concentration. Moreover, nucleotides significantly increased monounsaturated acids and linolenic acid and decreased eicosapentanoic and docosahexanoic acids. The unsaturation degree was higher in N than in C chickens and the atherogenic index was positively influenced. In conclusion, nucleotide dietary supplementation improved the physical and nutritional characteristics of the pectoralis major muscle of broiler chickens.
