Resumo

Background: Acute phase proteins (APPs) are clinically useful parameters for measuring the occurrence and severity ofinflammatory responses in cattle. As large group of proteins, APPs are mainly secreted by hepatocytes whose concentrationincrease or decrease as response to tissue injury, inflammation or infection. The transition from late pregnancy to earlylactation is associated with a compromised immune status coupled with increased acute phase response. Non-steroidalanti-inflammatory drugs (NSAIDs) are used in treatment of inflammatory conditions. The main objective of the presentstudy was to analyze the effects of a preventive administration of the NSAID (ketoprofen) in post-calving dairy cows onconcentration of APPs (haptoglobin and fibrinogen) and their relationship with indicators of liver function.Materials, Methods & Results: The treatment group (n = 15) was given an intramuscular injection of ketoprofen in theconcentration of 3 mg/kg during three consecutive days after calving. The control group (n = 15) was not treated withketoprofen. Blood samples were taken from coccygeal vein, on the first day of treatment and in the first and second weekpostpartum and they were analyzed for metabolic parameters (albumin and aspartat aminotransferaze) and APPs such ashaptoglobin and fibrinogen. Compared with control, ketoprofen administration decrease the levels of haptoglobin and fibrinogen and AST activity. Increase in albumin concentration was recorded in experimental group of cows compared withcontrol. Negative correlations (P < 0.01) were found between the haptoglobin concentration and albumin concentrationand aspartate aminotransferaze activity. Discussion: As inflammatory indicator in dairy cows, it is recorded that serum concentrations of haptoglobin is increasedduring mastitis. Beside haptoglobin, fibrinogen represents one of the APPs whose serum concentration increases during response in the acute phase. During the first and second week...(AU)
