The experiment was carried out in the district of Tamburco, province of Abancay, Peru, between January and April 2017 and aimed to determine serum levels of creatinine, urea and blood urea nitrogen (BUN) in guinea pigs fed with pisonay (Erythrina sp). Leaves and petioles of pisonay with four months of regrowth and fresh alfalfa (Medicago sativa) with 28 days of regrowth were used in the diet of 18 improved male guinea pigs. The animals were distributed in three treatments: A100: 100% alfalfa (80 g), A50P50: 50% alfalfa (40 g) plus 50% pisonay (40 g) and P100: 100% pisonay (80 g). The feed was provided twice a day. Serum creatinine levels in guinea pigs fed A50P50 and P100 were significantly higher compared to those that consumed A100 (p<0.05). The BUN levels were only significantly different between A100 and P100 (p<0.05), while there were no significant differences between treatme...

El presente estudio se realizó en Mosoccpampa, distrito de Tamburco provincia de Abancay región Apurímac, de enero a abril de 2017. Los objetivos fueron determinar los niveles séricos de creatinina y urea y la ganancia de peso vivo en cuyes. Se utilizaron 24 cuyes machos mejorados, distribuidos en tres tratamientos cada uno con 8 animales, con los siguientes tratamientos de alimentación: T1: 100% alfalfa; T2: 50% alfalfa más 50% pisonay y T3: 100% pisonay que se suministraron dos veces al día. Se utilizaron hojas y peciolos del pisonay con 4 meses de rebrote en estado verde y alfalfa fresca con 28 días de rebrote. Los niveles séricos de creatinina en cuyes (P≤0.05) alimentados con alfalfa más pisonay (T2) y pisonay (T3) fue significativamente mayor en 0.8 y 3.5 mg/dL con respecto a los animales que consumieron alfalfa (T3). La urea (P≥0.05) en cuyes alimentados con alfalfa ...
