Resumen:

The application of propolis ethanolic extract in pasture silage was evaluated in weaned lamb growth. Propolis produced by the Mexican stingless bee, Scaptotrigona mexicana, was extracted in ethanol and applied to pasture silage of Panicum maximum. Treatments were conducted in vitro to determine the degree of inhibition of pathogenic microbe growth in the silage and in vivo effect on weaned lamb growth. In vitro treatments of the bacteria Staphylococcus aureus (ATTC) 29,213, with ethanolic extracted propolis, resulted in a 90% inhibition. Silage color and pH were associated with these inhibition effects. Growth of weaned lambs (n = 30) was compared for three experimental diets: (1) pasture silage, (2) pasture silage + S. mexicana propolis ethanolic extract, and (3) pasture silage +70% ethanol. Weekly measurements of length, height at withers and thoracic perimeter in lambs were made as growth parameters. The palynological spectrum of propolis was analyzed. A richness of 32 taxa belonging to 21 botanical families was best represented by Cyperaceae, followed by Fabaceae, Piperaceae, Celastraceae, Moraceae, Asteraceae, and Euphorbiaceae, which could be responsible for their chemical properties for this botanical, geographical, and entomological origin. Thus, propolis addition did not affect pasture silage proximate chemical composition and did not affect palatability and growth of lambs. Finally, silage with S. mexicana PEE are useful to prevent spoilage by bacteria but not for fungi contamination. Moreover, lambs can be fed without risk of sickness. © The Author(s), 2024.
