The aim of the present study was to evaluate the effect of pinto peanut Arachis pintoi in guinea pigs in the growing stage. The experiment lasted for 49 days and included 64 weaned male guinea pigs, arranged in a completely randomized block design with four treatments (0, 5, 10, 15% levels of A. pintoi meal), with four repetitions and four guinea pigs per repetition The results indicate that there was no significant difference between A. pintoi levels for body weight gain, feed intake, feed conversion, carcass yield and economic retribution.

El objetivo del presente estudio fue evaluar el efecto del uso de harina de maní forrajero Arachis pintoi en cuyes en etapa de crecimiento. La duración experimental fue de 49 días, empleándose 64 cuyes machos destetados, dispuestos en un diseño de bloques completamente al azar con cuatro tratamientos (0, 5, 10, 15% de niveles de inclusión de harina de A. pintoi), con cuatro repeticiones y cuatro cuyes por repetición. Los resultados indican que no hubo diferencia significativa entre los niveles de A. pintoi para ganancia de peso, consumo de alimento, conversión alimenticia, rendimiento de carcasa y retribución económica.

This study was carried out to determine the digestibility coefficients and digestible energy of Arachis pintoi, Stylozanthes guianensis, Erythrina poeppigiana, Centrocema macrocarpum and Pueraria phaseoloides. The direct method was used, using the same forage as the only food. The experiment had two phases, one for adaptation and one of faeces collection, with duration of 15 and 5 days, respectively. We used 25 male guinea pigs in growth stage distributed in order to get 5 guinea pigs for each tropical legume evaluated. The digestibility coefficients of nutrients were numerically higher for Arachis pintoi (51,96, 56,80, 29,46 y 71,32 percent of the dry matter, crude protein, crude fiber and nitrogen free extract digestibility, respectively) than for all the other treatments, except for the ash. Likewise, digestible energy values (in dry basis) were greater for Arachis pintoi (2,20 kcal/g...
