Growth performance and diarrhea incidence in postweaning pigs, supplemented with plants mixed leaves powder, with nutraceutical properties

1 recurso en línea (páginas 19-26).To evaluate the plants mixed leaves powder dietary supplementation with nutraceutical properties effect by (40 % A. occidentale, 20 % M. oleifera, 20 % M. citrifolia y 20 % P. guajava) on growth performance and diarrhea incidence in post-weaning pigs, were used 150 piglets, with an average body weight of 7.74 kg±0.71 (Yorkland x Yorkshire) of 33 days old. A completely randomized design with six replicates per treatment, and five piglets per replicate during 42 days was applied. Treatments were T0: A basal diet (BD) without antibiotic growth promoter (AGP); (T1): BD + AGP (Labionor 5 mL/kg of fodder); (T2): BD +0.5 % of mixed powder, (T3): BD+1.0 % of mixed powder, and (T4): BD+1.5 % of mixed powder. Viability improved (P<0.05) with dietary supplementation of the mixed leaves powder and AGP compared with the T0. Also, the T3 and T4 increased (P<0.05) the final alive body weight,related to T0 and T1, as well as, the T4 which showed the best (P<0.05) average daily gain and feed conversion ratio, with significant differences (P<0.05) with the T0 and T1. The mixed powder supplementation and AGP decreased (P<0.05) the diarrhea incidence in post-weaning pigs. It is recommended the dietary supplementation of 1.0 % mixed leaves powders of plants with nutraceutical properties as alternative to the AGP, in order to increase the growth performance indexes and diminish the diarrhea incidence in post-weaning pigs.Para evaluar el efecto de la suplementación dietética con polvo mixto de hojas de plantas con propiedades nutracéuticas (40 % A. occidentale, 20 % M. oleifera, 20 % M. citrifolia y 20 % P. guajava) en el comportamiento productivo y en la incidencia de diarrea en cerdos posdestete, se utilizaron 150 cerdos (Yorkland x Yorkshire) de 33 días de edad, con peso vivo promedio de 7.74 kg±0.71. Se aplicó un diseño completamente aleatorizado con seis repeticiones por tratamiento y cinco cerdos por repetición, durante 42 días. Los tratamientos fueron, T0: Dieta Basal (DB) sin Antibiótico Promotor de Crecimiento (APC); T1: DB+APC (Labionor 5 mL/kg de pienso); T2: DB+0.5 % de polvo mixto; T3: DB+1.0 % polvo mixto, y T4: DB+1.5 % de polvo mixto. La viabilidad mejoró (P<0.05) con la suplementación dietética del polvo mixto y el APC, comparada con el T0; los T3 y T4 incrementaron (P<0.05) el peso vivo final con relación al T0 y al T1, y el T4 mostró (P<0.05) la mejor ganancia media diaria y conversión alimenticia, con diferencias significativas (P<0.05) con el T0 y el T1. Las suplementaciones del polvo mixto y del APC disminuyeron (P
