Clinically, out of the 75 milking cows in the first 8 week postpartum examined, 25 cows aged 4-8 years were found to be suffering from decreased milk production, severe body weight loss. 25 healthy cows in the same period after calving, aged 4-8 years, were also used as a control group. Serum biochemistry analyses including potassium (K), sodium (Na), calcium (Ca), phosphorus (P), magnesium (mg), albumin, alkaline phosphatase (ALP), gamma-glutamyltransferase (GGT), aspartate aminotransferase (AST), total biluribin, (TBIL) total protein (TP), creatinine (Cre), blood urea nitrogen (BUN), and β-Hydroxybutyrate (BHBA) were evaluated. Body condition score (BCS) of 17 of 25 cows, severe weight loss after calving cows, was ≤ 2.0 and BCS of 8 cows was between 2.0 and 3.0. BCS of Animals in the control group were determined as range: 3.5-4.0. Endometritis in 11 cows, subclinical mastitis in 8 cows, clinical ketosis in 5 cows, sub clinical ketosis in 20 cows, and left displaced abomasum in 3 cows were determined. Identical points of 25 animals were higher BHB, GGT, AST, total globulin, and total protein levels according to healthy cows and references values. In addition, these cows had hypoalbunemi and hypocalcaemia, when compared with healthy cows. The results of the study reported here indicated that metabolic profile including serum BHBA, calcium, albumin, GGT, AST, total protein, should be evaluated to determine the causes of severe weight loss, and decreased yield in cows after calving.

It’s almost impossible to detect the infection especially in early stages. This review present some of the diagnostic methods, their comparison and problems about diagnosis of paratuberculosis in the cattle.

Subclinical ketosis is a type of disease in which keton bodies in blood are elevated but not enough to cause clinical findings. Economic impact of subclinic ketosis makes disease one of the most important problems of dairy industry. Quick and accurate diagnosis of sublinical ketosis is crucial for economic development of a dairy herd thus in presented study two cowside BHBA test were compared according to two different blood BHBA cutoff values. Sensitivities were found to be 58%, 50% and specifities were 84%, 93% respectively for cut off points of 1.2 and >1.4mmol/L. overall specifity and sensitivity levels calculated indicates that Precision XtraTM could be used for detection of blood BHBA levels in suspected cows at the same time Precision XtraTM is quicker than Ketosite analysis takes 20 seconds per sample however with Ketosite one analysis takes about 2 minutes.

As a result of economic impact caused, disease is now one of the most important problems of dairy industry. Detection of animals shedding MAP organism plays a crucial role in herd eradication of the disease. Aim of the presented study was to evaluate relationship between MAP ELISA results, Intradermal Johnin test and fecal MAP shedding ratio. 40 ELISA and Johnin test positive animals were selected for the study. 25 of 40 animals (62.5%) were shedding MAP organisms with their feces. Results of the present study indicate that combination ELISA and Johnin test results is a useful tool for prediction of animals shedding MAP.
