Hematological Profile of Aceh Cattle

The study aimed to analyze the hematology profile, differential leukocytes, and the N/L ratio of Aceh cattle. The obtained result were compared to the data available for zebu (Bos indicus), Ongole grade (Bos indicus), and Bali cattles (Bos javanicus). The data would be important as a physiological reference of this cattle species. Blood samples were obtained from 17 adult male Aceh cattle which were slaughtered at slaughterhouses in Banda Aceh City and Aceh Besar District. The animals showed a healthy condition with an average body weight of 312.42 ± 66.91 kg. Blood was collected into the tube containing EDTA after the cattle were slaughtered. Blood analysis was done using hematology analyzer and staining the peripheral blood morphology. Data were expressed in the average and 95% confidence interval for further descriptive analysis. The average number of erythrocytes (x106 μl-1) of Aceh cattle reached 8.34 (95% confidence interval (CI); 7.32-9.36). The average number of leukocytes (x103 μl-1) 13.83 (95% CI; 10.26-17.40), hemoglobin (g dL- 1) 14.05 (95% CI; 11.85-16.25), hematocrit (%) 38.64 (95% CI; 29.90-47.38), MCV (fl) 46.16 (95% CI; 40.21-52.11), MCH (pg) 15.13 (95% CI; 13.65-16.61), MCHC (g dL-1) 32.96 (95% CI; 31.65-34.27), and platelets (x 103 μl-1) 226.20 (95% CI; 131.20-321.20). The average percentage (%) of lymphocytes, neutrophils, eosinophils, basophils, and monocytes were 61.69 (95% CI; 52.69-70.69), 30.59 (95%CI; 21.53-39.65), 6.31 (95% CI; 3.12-9.50), 0.51 (95% CI; 0.20-0.82), and 0.90 (95% CI; 0.43-1.37), respectively. The N/L ratio of Aceh cattle in the study was 0.66. The present study showed that profiles of hematology and differential leukocytes of Aceh cattle were generally similar to those of Bos indicus rather to those of Bos javanicus. Aceh cattle tend to be more adaptive to various exposure factors as indicated by the number of erythrocytes and a higher N/L ratio than other breeds.
