Efecto de la inclusión de orégano (Origanum vulgare) y cúrcuma (Curcuma longa) en dietas para pollos de engorde

Abstract

The poultry industry is in constant growth, seeking to improve productivity, which requires the incorporation of natural growth promoters to replace the use of antibiotics as growth promoters. The objective of this study was to evaluate the effect of the inclusion of oregano and turmeric meal on productive parameters and intestinal health in broilers, This study was carried out at the Irquis farm with 192 chicks divided into four treatments T0 (control), T1 (1% oregano), T2 (3% turmeric), T3 (1% oregano and 3% turmeric) and three replicates, during 21 days, feed consumption, weight and feed conversion (FC) were recorded, and intestinal villi and intestinal microbiota were evaluated. Cumulative feed intake and CA did not show significant differences between treatments, while weight gain was higher in T3 with an average weight of 0.55 kg. As for intestinal villi, there is no difference between treatments with respect to length, diameter and crypt depth; microbiological analysis showed varied bacterial growth. Proteus mirabilis, Staphylococcus spp, Klebsiella pneumoniae, enterococcus and Escherichia coli. There was a significant difference in the colony forming unit (CFU) count between T1 and T3. The addition of oregano decreased CFU. We can conclude that the simultaneous incorporation of oregano and turmeric improves weight gain without influencing other parameters and can be a viable alternative in broiler breeding, while the addition of oregano decreases CFU, improving intestinal health
