Evaluación del uso de probióticos y su efecto en los parámetros productivos en el engorde de cuyes

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.
