Abstract
El objetivo del estudio fue determinar los niveles séricos de creatinina, nitrógeno ureico en sangre (NUS) y la relación riñón peso vivo de cuyes (Cavia porcellus) alimentados con la inclusión de harina de pisonay (Erythrina edulis) de 3 edades de rebrote en el sector de Mosoccpampa, Apurímac. Se utilizaron 80 cuyes machos mejorados, que fueron distribuidos al azar en grupos de 8 cuyes para cada tratamiento dietético que contenía 10, 20 y 30 % de inclusión de harina de pisonay (HP) por cada edad de rebrote de 4, 8 y 12 meses y un grupo control con 20 % de harina de alfalfa en condiciones isoprotéicas e isoenergéticas. Se tomaron muestras de sangre con finalidad de determinar la actividad sérica mediante kits comerciales (Valtek Diagnostics) para fotometría. Los datos fueron analizados bajo el diseño completamente al azar y para la comparación de medias se aplicó el contraste de Dunnett's (p≤0.05). Los niveles séricos de creatinina de las dietas D2, D3, D4 y D8 (0.61, 0.68, 061 y 0.66 mg dL-1 respectivamente) fueron diferentes al grupo control 0.48 mg dL-1 (p<0.05). Los niveles de NUS de las dietas D1 21.26 mg dL-1 y D7 14.05 mg dL-1 fueron diferentes al grupo control 17.56 mg dL-1 (p<0.05). La relación riñón peso vivo en las dietas (0.85 %) fueron similares a la dieta control 0.87 % (p>0.05). Los valores de creatinina sérica, NUS y la relación riñón peso vivo no fueron afectados por la inclusión de HP de 3 edades de rebrote en la dieta, esté comportamiento nos indicaría que la HP podría ser considerado como insumo para elaborar alimento integral para cuyes en la etapa de crecimiento.
The objective of the study was to determine the serum levels of creatinine, blood urea nitrogen (BUN) and the kidney weight ratio of guinea pigs (Cavia porcellus) fed with the inclusion of pisonay (Erythrina edulis) meal of three regrowth ages in the Mosoccpampa sector, Apurímac. Eighty improved male guinea pigs we´re used, which we´re randomly distributed into groups of 8 guinea pigs for each dietary treatment containing 10, 20 and 30 % inclusion of pisonay meal for each regrowth age of 4, 8 and 12 months and a control group with 20 % alfalfa meal under isoproteic and isoenergetic conditions. Blood samples we´re taken to determine serum activity using commercial kits (Valtek Diagnostics) for photometry. The data we´re analyzed under the completely randomized design and for the comparison of means, the Dunnett´s test was applied (p≤0.05). Serum creatinine levels of the D2, D3, D4 and D8 diets (0.61, 0.68, 061 and 0.66 mg dL-1 respectively) were different from the control group (0.48 mg dL-1) (p<0.05). BUN levels of the D1 (21.26 mg dL-1) and D7 (14.05 mg dL-1) diets were different from the control group (17.56 mg dL-1) (p<0.05). The kidney weight ratio in the diets (0.85 %) was similar to control diet (0.87 %) (p>0.05). The values of serum creatinine, BUN and kidney weight ratio we´re not affected by the inclusion of pisonay meal of three regrowth ages in the diet, this behavior would indicate that pisonay meal could be considered as input to produce integral food for guinea pigs in the growth stage.
