Evaluación de IMUN+Animals sobre los parámetros productivos y salud intestinal en cerdos (Sus scrofa domesticus) de recría

Abstract

The aim of this research was to evaluate IMUN+Animals on productive parameters (weight gain, feed consumption, feed conversion, morbidity, mortality) and intestinal health in rearing pigs (Sus scrofa domesticus). This research was carried out in Ambato, Izamba parish, Tungurahua province. We worked with 30 rearing pigs established in three treatments: a control group (T0) free of product, treatment 1 (T1) with IMUN+Animals at a dose of 0.20% in drinking water from weaning to 12 kg live weight (LW), and finally a treatment 2 (T2) with a reducing dose, 0.20% in drinking water up to 12 kg LW, then 0.10% up to 17 kg LW, and 0.05% up to 30 kg LW, the doses were recommended by the manufacturer and considering the doses of similar products marketed in Ecuador. The results obtained suggest that there are no differences between the use of the product and control group (T0). Only total weight gain showed a significant difference between groups (p=0.013), with the control (T0) showing the best performance. Regarding the clinical evaluation carried out weekly on the animals, no changes were observed during the experiment, so the mortality and morbidity values were 0% in all groups. Feces showed differences between groups, being solid and well formed in the group that received the product during the entire rearing phase (T2) and in T1 while receiving the product, but soft and well formed in the control group (T0) and in treatment 1 (T1) once the administration of the product has concluded. The analysis of intestinal villi and crypt depth showed no difference between groups. In conclusion, the administration of IMUN+Animals does not improve the productive parameters of pigs in the rearing phase under the doses applied in this study, however, it is estimated that it can improve the consistency and presentation of feces in the treated animals, which suggests better intestinal function.
