In swine, the studies and innovations on homeopathic, phytotherapeutic, symbiotic and other additives have been highlighted in order to replace or diminish the use of antimicrobials promoters at all productive phases. Therefore, objected evaluate effects of the inclusion of homeopathic products in pig feed in the growth and finishing phases on performance, blood parameters, carcass characteristics, meat quality and feed digestibility. Sixty entire male pigs were used, immunocastred at 90 and 120 days old, with a mean initial weight of 30.91 ± 0.95 kg. The animals were distributed in a completely randomized design, within two treatments, 10 replicates and 3 animals per experimental unit. The treatments consisted of a control diet and control diet plus the inclusion of 6.0 kg/ton of two commercial homeopathic products (figotonus® and sanoplus®), being 3.0 kg of each. The performance of the animals was evaluated in two productive phases (growth and termination) and in the total period. Statistical analyzes were analyzed using the SAS program (2015) and the data were submitted to analysis of variance at probability of 5.0%. There was no difference between treatments for the performance parameters (P≥0.05) in any of the phases, as well as for blood parameters (plasma urea nitrogen - NUP and aspartate aminotransferase enzymes - AST and alanine aminotransferase - ALT). There was an increase (P≤0.05) in the percentage content of acid-insoluble ash in the diet (CIA-ration) and reduction in apparent digestibility coefficients of dry matter, crude protein, neutral detergent fiber, acid detergent fiber and of crude energy in both phases, as well as in the digestibility coefficient of the organic matter and in the digestible energy of the growth phase; except (P≥0.05) for the apparent digestibility coefficient of ethereal extract, percentage of CIA-feces and crude energy in the two phases analyzed, in addition to the coefficient of apparent digestibility of organic matter and digestible energy in the finishing phase. Regarding the carcass characteristics, a higher amount of meat (P = 0.05), muscle percentage (P = 0.04) and greater degree of marbling (P = 0.04) were observed in animals receiving homeopathic products. It was concluded that the use of homeopathic products positively affected the performance of the animals, the percentage and quality of meat, as well as the degree of marbling of the carcasses of these animals. Therefore, they can be used in pig diets in growth and finishing stages in order to improve the quantity and quality of carcass.
