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...

The experiment was conducted to determine the digestibility coefficients and digestible energy of kudzu meal (Pueraria phaseoloides) in guinea pigs. Ten male guinea pigs of 12 weeks and 828 g of average weight were placed in metabolic cages. Five animals were fed the basal diet (wheat by-product) and the other five were fed with the experimental diet (60% wheat by-product and 40% kudzu meal). The indirect method was used for these determinations. The wheat by-product meal was used as a basal feed and its digestibility coefficient was determined by the direct method. There was a 14-day pre-experimental phase for the adaptation of the animals to the facilities and the new diet. The experimental phase was six days, in which the stool collection was performed. In both phases, feed consumption was measured daily. The apparent digestibility coefficients obtained were: 42.90% dry matter, 40.57%...

This study aimed to determine the apparent digestibility coefficients and digestible energy of dry velvet bean fodder (Mucuna pruriens). The indirect method was used, considering as a basal diet the concentrate used in the university guinea pig farm (Lima, Peru). The experiment had an adaptation phase (14 days) and a faecal collection phase (5 days). Ten adult male 3-month old guinea pigs randomly distributed in individual metabolic cages were used. Five animals were fed the basal diet and the other five with the experimental diet: 80% basal diet and 20% dry velvet bean fodder. The apparent digestibility coefficients obtained for the dry velvet bean were: 66.29% dry matter, 66.13% organic matter, 74.02% crude protein, 50.82% crude fibre, 60.18% ether extract, 78.22% nitrogen-free extract and 73.33% ash. The estimated digestible energy value was 2.61 kcal/g.
