Abstract
El presente trabajo de investigación se realizó con la finalidad de evaluar el uso de probióticos y su efecto en los parámetros productivos en el engorde de cuyes, el experimento se llevó a cabo en la granja experimental de la Pontificia Universidad católica del Ecuador sede Ibarra, Ubicada en la Victoria, cantón Ibarra, provincia de Imbabura ubicada a 2220 m.s.n.m, en dicho experimento se utilizó un Diseño Experimental Completamente al Azar (DCA), se evaluó 3 diferentes concentraciones de probióticos en el alimento (T0: alfalfa sin probióticos, T1: Alfalfa con probióticos concentración 2x106 ufc/ml, T2: Alfalfa con probióticos concentración 2,5x1010 ufc/ml), se utilizaron 45 cuyas hembras en fase de engorde, las cuales se distribuyeron de manera uniforme en 9 unidades experimentales. Se recopilaron datos semanalmente, desde la semana 1 hasta la semana 8 que concluyo el experimento, para poder evaluar los parámetros planteados: ganancia diaria de peso, conversión alimenticia, porcentaje de mortalidad y peso a la canal. Para establecer la efectividad de los tratamientos se utilizó el análisis de varianza con una prueba de Shapiro-Wilks y prueba de Tukey al 5%. Obteniendo como resultado favorable el tratamiento T1: Alfalfa con probióticos concentración 2x106 ufc/ml en la variable de ganancia diría de peso y conversión alimenticia, por el contrario, en la variable porcentaje a la canal obtuvo un mejor resultado el tratamiento T2: Alfalfa con probióticos concentración 2,5x1010 ufc/ml.
The present research work was carried out with the purpose of evaluating the use of probiotics and their effect on the productive parameters in the fattening of guinea pigs. The experiment was carried out in the experimental farm of the Pontifical Catholic University of Ecuador, Ibarra headquarters, located in La Victoria, Ibarra canton, province of Imbabura located at 2220 meters above sea level, in this experiment a Completely Randomized Experimental Design (DCA) was used, 3 different concentrations of probiotics in the food (T0: alfalfa without probiotics, T1: Alfalfa with probiotics concentration 2x106 cfu/ml, T2: Alfalfa with probiotics concentration 2.5x1010 cfu/ml), 45 were used whose females in the fattening phase, the which were distributed evenly in 9 experimental units. Data were collected weekly, from week 1 to week 8, when the experiment concluded, in order to measure the proposed parameters: daily weight gain, feed conversion, mortality percentage and carcass weight. To establish the effectiveness of the treatments, analysis of variance was used with a Shapiro-Wilks test and a 5% Tukey test. Treatment T1: Alfalfa with probiotics concentration 2x106 cfu/ml was obtained as a favorable result in the variable of weight gain and feed conversion, on the contrary, in the variable percentage to the carcass, treatment T2: Alfalfa with probiotics obtained a better result. concentration 2.5x1010 cfu/ml.
