Efecto de la Inclusión de Diferentes Niveles de un Preparado Microbiano en Porcinos en la Etapa de Post-Destete

Abstract

In pig production Unit of Ciencies Pecuarias Faculty, Escuela de Ingenieria Zootecnica at ESPOCH, which is located in Riobamba Cantòn, Chimborazo Province. It was evaluated the effect of different levels including a microbial preparation in pigs F1 landrace x Largue White witch faster finisher Belgain Whithe x Pietrain, in the Post – Weaningv stage, distributed under a completely Randomized Desing and evaluating different variables for 120 days of investigation. Determining the highest total weight gain and daily 20.25 Kg and 428.14g respectively, included in the diet supplied microbial preparation in doses of 15 cc/Kg live weight, with what is established the value efficient in feed conversión whit 1.87. Moreover, the the best profitability in the stage of post – weaning pigs was determined in animals treated with the microbial preparation supplied in doses of 15cc/Kg of live weigth, achieving a level of profit – cost 1.69 USD. It is recomended the use of 15cc/Kg of live weigth of the combined microbial, in pigs in post – weaning stage because in the present investigation were stablished the more efficient parameters in terms of production and economic yields. In addition, share the results of this research at the level of semi – intensive farms and allowing a better adaptation of the pigs during post – weaning stage order preveting digestive diseases in animals.
