Evaluation of Some Hematological and Biochemical Changes in Iodine-Deficient Calves

Iodine deficiency is a significant issue affecting calves in Egypt. This study investigates the impact of iodine deficiency on various hematological and biochemical parameters. A total of 100 calves, aged between 9 months and 2 years, exhibiting clinical signs such as general weakness, dullness, reduced appetite, alopecia, and weight loss, were sourced from the New Valley Governorate. 20 healthy calves, free from external and internal parasites, were selected from a farm in the Assiut Governorate as control animals. Our findings revealed a significant reduction in urinary iodine levels, as well as in T3, T4, glucose, glucagon, insulin, total protein, albumin, globulin, Hb, and R.B.C.s levels in the affected calves compared to the control group. Conversely, there was a significant increase in levels of TSH, ALT, AST, and urea, W.B. Cs, as well as a non-significant elevation in creatinine levels in the diseased calves diagnosed with iodine deficiency compared to the control group.
