Resumen

The effect of a probiotic compound (PC) containing Lactobacillus sp., Bifidobacterium sp., and Saccharomyces sp., at a concentration of 2×107 CFU·mL-1, on the productive performance and carcass yield of meat guinea pigs was evaluated. Sixty–four male and female guinea pigs, 28 ± 3 days old, with weights between 384.3 and 453.2 g, were raised in four–level cages and fed fresh alfalfa and a balanced supplement with 500 ppm of inulin, during 10 weeks. The treatments consisted of oral administration of 0,0; 1.0; 1,5, and 2,0 mL·animal-1 of PC at the start and in weeks 3 and 6. Weight gain (WG), feed intake (FI), feed conversion ratio (FCR), and carcass yield (CY) were measured. The data were analyzed using a randomized complete design, and Tukey’s test was applied for mean comparisons. The doses of 1,5 and 2,0 mL of PC significantly improved feed conversion and carcass yield, while reducing feed intake, with no significant improvements in weight gain. It is concluded that the probiotic mix containing acidophilic bacteria at a concentration of 2×107 CFU·mL-1 improves feed conversion efficiency and carcass yield in meat guinea pigs. © (2025), (Revista Cientifica de la Facultad de Veterinaria).
