Resumen

This study aimed to evaluate the hematological profile of guinea pigs supplemented with Erythrina edulis leaf meal. Erythrina edulis leaves were collected at the regrowth ages of 4, 8, and 12 mo (A4, A8, A12), ground into meal, and included in the diets for guinea pigs at 10, 20 and 30 % (P10, P20, P30). A total of 80 improved and weaned male guinea pigs were randomly distributed for each diet. After 56 d, blood was collected directly from the jugular vein in EDTA tubes to analyze erythrocytes, mean corpuscular volume, hematocrit, hemoglobin, leukocytes, platelets, and mean platelet volume. Erythrocytes and hemoglobin were similar between diets. The factors of age and meal inclusion did not affect the values found in erythrocytes, mean corpuscular volume, hematocrit, and hemoglobin. The age factor (A4:8.55; A8:11.92; A12:10.14 x103/ul) and meal inclusion (P20:11.11; P30:12.08; P10:7.43 x 103/uL) caused differences in leukocytes. Platelets were affected by the age factor (A4:391.98; A12:400.67; A8:467.08 x 103/uL) and meal inclusion factor (P10:444.22; P20:443.05; P30:372.45 x 103/uL). The mean platelet volume showed variations due to the age factor (A8:11.39; A12:11.31; A4:11.90 fL). Erythrina edulis leaf meal in guinea pig diets has potential as a feed input without altering the hematological profile, which would indicate that age and inclusion factors would not cause toxicity.
