TLDR
A significant reduction of main inflammatory mediators PGE2, PGF2alpha,TXB2 and MDA after meloxicam treatment in calves with induced bronchopneumonia indicates a beneficial effect on the inflammatory processes.Abstract:
The influence of treatment with steroidal (SAIDs) and non-steroidal (NSAIDs) anti-inflammatory drugs on inflammatory markers in thirty, 6-8 week old calves with induced bronchopneumonia was investigated. Animals received a single intravenous treatment with meloxicam (0.5 mg/kg body weight), flumethasone (0.05 mg/kg body weight) or sterile 0.9% NaCl (10 ml per animal). Body temperature, respiratory and heart rate, concentration of prostaglandins PGE2, PGF2alpha, thromboxane (TXB2), leukotriene (LTB4) and malonyldialdehyd (MDA) and proinflammatory cytokines i.e. tumor necrosis factor (TNFalpha) and interferon (INFalpha) were recorded in serum, bronchoalveolar lavage (BAL) and blood platelets (BP). A significant reduction of main inflammatory mediators PGE2, PGF2alpha,TXB2 and MDA after meloxicam treatment in calves with induced bronchopneumonia indicates a beneficial effect on the inflammatory processes. Contrary to effects observed by flumethasone, meloxicam induced an increase of LTB4 and INFalpha indicating that it is not immunosuppressive.read more

TL;DR: A respiratory acidosis and an early inflammatory cytokine production occur during BRD, mainly related to the BVDV and M. heamolytica as most common agents involved in the disease.

Bovine Respiratory Syndrome (BRD) Etiopathogenesis, Diagnosis and Control
TL;DR: Bovine respiratory disease (BRD) complex is a major disease, classically in the indoor calves and feedlot young cattle, and the one of the most often isolated mycoplasmal factors from BRD cases is Mycoplasma bovis.
