RESUMEN
Background: Hematological and biochemical values are widely used in veterinary clinics for disease prognosis, nutritional and therapeutic monitoring, as well as in understanding the disease process in farm animals, including equines. Aim: This study aims to assess the alterations in hematological and biochemical parameters in pure Arabian horses infested with internal parasites. Methods: Samples of feces and blood were collected from 20 adult mares. Fecal samples were proceeded by flotation test. The blood samples were analyzed for hematological and biochemical parameters to determine their means ± standard error (M ± SE). We compared the M ± SE with the reference values cited. Results: Infestation percentage was as (%) Parascaris equorum 3 (15%) and 17 (85%) mixed infestation, Strongylus species with P. equorum. The hematology of our Arabian horses shows a little variation of values compared to normal reference values, in hemoglobin level (g/dl), packed cell volume (%), red blood cell count (106/µl), and white blood cells count (103/µl), mean corpuscular volume (fl), mean corpuscular hemoglobin (pg) and mean corpuscular hemoglobin concentration (g/dl). In addition, their serum biochemistry showed blood glucose (mg/dl), urea (mg/dl), creatinine (mg/dl), albumin (g/dl), sodium, potassium, and chloride (mEq/l) within normal reference values. Conclusion: Our study did not show variation in hematology or chemical values compared to the normal values. We attributed this a result of the quantity and quality of nutrition given to the horses, which compensate for the damage caused by these parasites, so this study may provide useful diagnostic indices for Arabian horses.
