Blood and parasitological parameters of sheep experimentally infected with Haemonchus contortus and treated with “mushroom of the sun” (Agaricus blazei) were assessed. Lambs infected with the nematode were divided into three groups: treated with basidiocarp powder from the fungus, wormed with trichlorfon, and a control group that did not receive anthelmintic. Split-plot design analysis was performed where the treatments were defined as plots and four periods of collection were defined as subplots. Interaction between the treatments and the collection periods for the fecal egg counts per gram of feces (FEC) was observed. Treatment with “mushroom of the sun” showed anthelmintic efficacies ranging from 28.6 to 54.2%. Similar performances to weight gain were observed among the groups. A significant interaction between treatments and evaluation periods was observed for erythrocyte counts, hematocrit value, and serum concentrations of albumin and urea. The values of the mean corpuscular volume, erythrocyte distribution width, and leukocyte, neutrophil, lymphocyte, monocyte, and eosinophil counts, as well as the mean platelet volume, varied among the collection days. The administration of “mushroom of the sun” significantly reduced the FEC, did not influence on the erythrocyte count and hematocrit value, which remained within normal limits. However it increased the serum concentrations of albumin.
