Hematological and Biochemical Analysis of Asymptomatic Fascioliasis of Bali Cattle (Bos Javanicus)

: The research was to examine the hematological characteristic of fascioliasis in Bali cattle in year-round irrigated rice fields in tropical areas. Fifty cattle raised in rice field areas were examined by hematology, coproscopy, physiology, and liver function tests. The results showed that 50 cattle had heartbeat, respiratory and rectal temperature in normal standard, but, 41 (82%) out of 50 cattle were found positive for Fasciola eggs with egg per gram (epg) varying from 1 to 30. Indicators of liver function such as total bilirubin, alanine Amino Transferase (ALT), and Alkaline Phosphatase (AP) were under the normal conditions, except ɣ-Glutamyl Transferase (GGT) which was higher than the normal standard, indicating long-term liver damage and aspartate Amino Transferase (AST) less than normal on two cattle. Examination of Red Blood Cells (RBC) showed that 3 out of 20 cattle had an erythrocyte of 4.30 (10 6 /µL) which can be categorized as anemia; 3 out of 20 cattle had higher Mean Corpuscular Volume (MCV) than normal, which indicated as a macrocytic condition. Mean Corpuscular Hemoglobin (MCH) in all the cattle was higher than 17 (p.g.,) which indicated hyperchromic erythrocyte, while MCHC was still at the normal levels. In terms of WBC, 8 out of 20 cattle showed leukocytes concentration higher than 12 (10 3 /µL), and 6 cattle had eosinophils, band neutrophils, segmented neutrophils, and monocytes higher than the normal level and 6 cattle showed platelet concentration less than 100 (10 3 /µL).
