In this study, importance of some clinical, hematological, biochemical, electrocardiography findings in the preoperative and postoperative period on the diagnosis, prognosis, and treatment of cattle with Traumatic Reticuloperitonitis (TRP) was investigated. This study was carried out on 30 cattle (from 2 to 8 years old) with TRP. Systematic clinical examinations and laboratory analyses were conducted on all cattle. ECGs of these cows were examined using base-apex (BA) derivation. Ruminal fluid examination (pH, total number of infusoria, Cl– concentration), some hematological analysis (heamatocrite values, total leukocyte counts, leukocyte formula), venous blood gases (pH, HCO₃, pCO₂, and BE values), and biochemical analysis (serum K⁺, Na⁺, Cl^–, Ca⁺⁺, inorganic P, Mg⁺⁺, total protein, albumin, and globulin) were performed.

Results of findings from clinical examination indicated that, body temperature, respiratory and pulse rates was significantly (P<0.05) higher whereas ruminal motility was significantly (P<0.05) lower at preoperative period compared to postoperative period.

In ruminal fluid examination, a significant decrease (P<0.05) was found in pH and in numbers of total infusoria while a significant increase (P<0.05) was observed in sedimentation and flotation in the preoperative period.

In hematological examination, a significant increase (P<0.05) was found in total leucocyt number and in level of neutrophil (%) while a significant decrease in lymphocytes (%) (P<0.05) was found in the preoperative period.

In biochemical analysis, a significant decrease (P<0.05) was found in Ca⁺⁺, inorganic P, Mg⁺⁺, total protein and albumin concentration and ration of albumin/globulin in the preoperative period.

In venous blood gases analysis, a significant decrease (P<0.05) was found in pH values in the preoperative period.

In ECG of cows in the preoperative period, 5 cattle had sinus tachycardia.

As a result, a success rate of 93% was achieved in surgical treatments and it was concluded that hematological, biochemical and electrocardiographicl findings before and after operation may provide valuable information about differential diagnosis, prognosis, and treatment of RPT.
