Resumen

This research aimed to evaluate of nanoencapsulated essential oils of soursop, lemon, and eucalyptus as natural alternative growth promoters on productive parameters and meat quality in Guinea pigs compared to a commercial promoter. One hundred both sex Guinea pigs were used, randomly distributed into 5 treatments using completely randomized design; T0: commercial feed + 500 g of zinc bacitracin/t of feed, T1: Balanced feed + 33.4% soursop essential oils + 33.3% lemon essential oils + 33.3% eucalyptus essential oils, T2: Balanced feed + 50% soursop essential oils + 25% lemon essential oils + 25% eucalyptus essential oils, T3: Balanced feed + 50% lemon essential oils + 25% soursop essential oils + 25% eucalyptus essential oils, and T4: Balanced feed + 50% eucalyptus essential oils + 25% soursop essential oils + 25% lemon essential oils, at a dose of 75 g·t-1 of feed.The Guinea pigs were subjected to productive characteristics and meat quality. Data obtained was analysis using analysis of variance followed by Tukey’s test to identify statistically significant differences. Statistically significant differences (P<0.05) were observed in weight gain, carcass weight, carcass yield, and meat pH. The results indicated that nano–encapsulated essential plant oils could effectively replace commercial growth promoters due to their positive impact on productive parameters. Furthermore, these natural alternatives produced meat of comparable quality to the chemical growth promoter in terms of dry matter percentage, ash content, abdominal fat weight, and water retention capacity. © (2026), (Universidad del Zulia).
