The food industry is in a continuous search for strategies of reducing of antibiotic residues in livestock production, given the development of antibiotic-resistant bacteria. In that context, there is a consistent increasing in the usage of alternative feed phytogenic additives. Due to the pharmacological, the plants Marrubium vulgare and Leonurus sibiricus, are both potential replacements for growth-promoting antibiotics. This study evaluated the productive performance and analyze the sensory qualities in the meat of broiler that were administered M. vulgare and L. sibiricus infusions. A total of 320 chicks from an poultry farm were distributed in 8 groups groups according treatments by 28 days: Control Group (Saline); Positive control (tylosin 1%, 50 ppm); Groups of M. vulgare (MV) infusion: 2% (MV2), 4% (MV4) and 6% (MV6); and groups treated with L. sibiricus (LS) infusion: 2% (LS2), 4% (LS4) and 6% (LS6), all of them received relative doses corresponding to the live weight percentage in milliliter. There was weght gain in MV6 and LS6 group and a better food conversion in MV4, MV6, LS4, and LS6. In addition, weight gain and enhancement of the pectoral muscles were observed in these groups. The sensory analysis revealed that the broilers’ meat of MV had a more intense flavor. For marketing purposes the meat from birds that received LS had a better demand. Improvement of productive performance and sensory qualities of the broilers meat might be associated with the phytobiotic activity in it. Therefore, MV and LS can be used as natural growth promoter in broilers.
