Aprovechamiento proteico de la suplementación con Saccharomyces cerevisiae en cobayos (Cavia porcellus)

Abstract

To improve the productive parameters of guinea pigs, the objective was to evaluate the protein utilization of Saccharomyces cerevisiae supplementation in guinea pigs (Cavia porcellus). The research began with the adaptation of the guinea pigs to the shed, dividing them into 3 treatments with 2 repetitions each; the groups consisted of 8 animals per cage, having a total of 72 experimental units, the present work had a duration of 8 weeks; Treatment 1 consisted of Ration 13% protein + Saccharomyces, Treatment 2 Ration 15% protein + Saccharomyces, Treatment 3 Ration 17% protein + Saccharomyces and T0 (Ration 13% protein; Ration 15% protein; Ration 17% protein) it should be noted that in each repetition another level of Saccharomyces Cerevisiae was used. For the statistical analysis, a completely randomized block design (CRBD) was used, blocked by house location based on the treatments. No statistical differences were observed between treatments; however, we present T3 as the best result in the final weight, weight gain, feed intake, and feed conversion with 915.38 g. 87.75 g. 515.12 g. and 5.95 g. respectively.
