Probiótico natural en la alimentación de porcinos en las etapas de crecimiento y engorde con diferentes niveles de soluto

Abstract

Three treatments with natural probiotic with 50, 60, 70 % of wheat bran as a solute compared to a control treatment with 0% of natural probiotic without growth prometer were studied in the pig Production Program of the Faculty of Animal Sciences of ESPOCH, located in the city of Riobamba Km 1 1/2 Southern Pan-American Highway, province of Chimborazo. 16 piglets were used for this investigation in the post- weaning 60 days old, of mixed breed York x Landrace, which were divided into four replicates with an experimental unit for each treatment, distributed under a completely random design. It has been determined that in the growth stage the best results in final weight (57.30 kg), weight gain (38.86 kg) and better feed conversion efficiency (2.24) was obtained with the use of natural probiotic plus 50% of solute (T1); equally favorable results were obtained in the fattening phase in respect of the final weight (103,76Kg), weight gain (46.38 kg), the lower cost / kg of food ($ 1.20) and efficient conversion food (2.72).The highest rate of benefit / cost in the grow-finish stage was 1,38USD, it means that it was achieved a profitability of 38% .Therefore it is suggested to include in the diet the natural probiotic with the addition of 50% of solute ( T1 ) , since the best production and economic parameters were recorded.
