Many diseases, including renal disorders in ruminants, appear in subclinical form and lead to reduced production without causing clinical signs. In this research, blood and tissue samples of kidney were taken from 102 buffaloes from Ahvaz industrial abattoir and sent to the laboratory for biochemical and histopathological analysis. After preparing the pathological sections from kidney specimens, conventional and specific staining and microscopic examination, 41 samples had no kidney lesion was considered as control and 61 specimens as the lesion group. The samples with renal lesions were divided into 4 subgroups including acute tubulointerstitial nephritis, chronic tubulointerstitial nephritis, Urinary tubular inflammation, and Congestion. The samples were also divided and compared to males and females. In blood samples, serum biochemical tests including parathyroid hormone, erythropoietin, and vitamin D3 were measured by using ELISA-specific commercial kits. After statistical analysis, the results of vitamin D3 in the studied groups did not show any significant difference. However, erythropoietin and parathormone values in buffaloes with renal lesions were significantly lower and higher than those in control animals respectively. The results of this study showed that most of the kidney lesions in the studied buffaloes including the mentioned above have led to a decrease in the production of erythropoietin hormone following the occurrence of these lesions and its functional effects on the kidneys. Naturally, the effects of this hormone deficiency are expected to be reflected in the hemogram and eventually, anemia resulting from it may affect overall body health.
