الملخص EN

This study was conducted on a total number of 51 newborn buffalo calves in two farms in Ismailia governorate.

The most evidenced clinical signs of bronchopneumonia in newborn buffalo calves were polypnea, anorexia, depression, weakness, bilateral copious mucoid and mucopurulent nasal discharge, coughing, unilateral or bilateral ocular discharge and dyspnea that were evidenced in some cases.

Also, the tracheal sound was exaggerated and accompanied sometimes with rattling and/ or stenotic sound while auscultation of the lungs revealed presence of mixed abnormal sounds in different areas of both lungs that were soft crackles, coarse crackles and wheezes.

A significant hypoxemia with a non significant changes of PaCO2 and blood pH were recorded in acute and chronic cases meanwhile, died cases recorded a significant hypoxemia, acidosis and hypercapnia.

The blood bicarbonates concentration recorded a non significant change in diseased calves.

It could be concluded that bronchopneumonia has a harmful effect on general health condition in newborn buffalo calves as well as on blood gases and acid- base balance, even death may be occurs in neglected cases.
