Productive Behavior of Pigs Fed with Pelled Feed Plus the Addition of a Microbial Preparation

Abstract This study aimed to assess the performance of pigs in terms of productivity when they were given pelleted feed along with microbial preparations at Paty Pig Farm in Yaruquies parish, Riobamba Canton, Chimborazo province. The duration of the study was 90 days and included 48 piglets of Yorkshire x Landrace crossbreed. These piglets were weaned at 21 days of age and weighed an average of 6.5 kg, with 24 males and 24 females. The study used three different levels (2%, 4%, and 6%) of microbial preparation in comparison to a control group. A completely randomized design (DCA) was used in combination with two factors: prebiotic addition (factor A) and animal gender (factor B). The productive behavior of pigs showed no significant differences in the parameters such as feed intake, total feed intake, and feed conversión, among the groups. However, the final weight and weight gain showed better results in the groups that received microbial preparation. The study suggested that microbial preparation levels of 2%, 4%, and 6% can be used as it improved the final weight and weight gain by 37.57 kg and 30.70 kg, respectively, compared to the control group. No mortality was reported due to the use of microbial preparation. The study recommends the use of microbial preparation in other stages of pig production to verify its benefits. Keywords: pig fattening, microbial preparation, pelletized feed, productive parameters. Resumen El presente trabajo tuvo como objetivo evaluar el comportamiento productivo de los cerdos alimentados con alimento peletizado más la adición de preparado microbianos en la Granja Porcina Paty en la parroquia de Yaruquies del Cantón Riobamba, de la provincia de Chimborazo. El tiempo de duración de la investigación fue de 90 días, para el desarrollo se utilizaron 48 lechones que son un cruce de Yorkshire x Landrace estos fueron destetados de 21 días de edad y de un peso promedio de 6,5 kg, de los cuales 24 fueron machos y 24 hembras. Para el desarrollo de la presenta investigación se utilizaron tres niveles (2, 4 y 6 %) de adición de preparado microbiano, para ser comparados con un tratamiento control. Se aplicó un diseño completamente al azar (DCA), en arreglo combinatorio de dos factores; donde el factor A corresponde a la adición de probióticos y el factor B al sexo de los animales. El comportamiento productivo de los cerdos durante el crecimiento y engorde no reportó diferencias significativas en los parámetros consumo de balanceado, consumo total de alimento y conversión alimenticia; mientras que para las variables peso final y ganancia de peso se reporta resultados favorables para los tratamientos que se utilizó un preparado microbiano. Se concluyó que se puede utilizar los niveles de preparado microbianos (2, 4 y 6 %) debido a que mejoró el peso final 37,57 kg y ganancia de peso 30,70 kg, en comparación con el tratamiento testigo, además con su utilización no se reporta mortalidad alguna. Se recomienda utilizar el preparado microbiano en otras etapas de producción de cerdos para comprobar sus beneficios.
