Indicators of kidney function in guinea pigs (Cavia porcellus) fed with the inclusion of pisonay (Erythrina edulis) meal of three regrowth ages. J.Selva Andina Anim. Sci. [online]. 2024, vol.11, n.1, pp.13-22.  Epub 01-Abr-2024. ISSN 2311-3766.  https://doi.org/10.36610/j.jsaas.2024.110100013.

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.
