Abstract

The objectives of this study were to apply different methodsfor diagnosis of caprinepneumonia and to study the correlation between vitamin D concentration and the immunoglobulins (IgG, IgM, IgA) in goats up to one year in response to pneumonia.
From October 2018 to February 2021, a total of 107 baladi goats were includedexamined; 20 apparently healthy goats used as control group (group I, n=20) and 87 pneumonic baladi Baladi goats were diagnosed on the basis of clinical symptoms, ultrasonographic, chest x-ray findings. Serum vitamin D, IgG, IgM and IgA levels were also measured. Pneumonic goats (group II, n= 87) were subdivided into two groups according to their vitamin D levels; pneumonic goat with normal vitamin D level (groupII a, n= 38) and pneumonic goat with decreased vitamin D levels (groupIIb, n= 49). Pneumonic goats were presented with fever, dullness, tachypnoea, bilateral mucoid or mucopurulent/purulent nasal discharge, cough, dyspnea and abnormal lung auscultation. Ultrasonography, the pneumonic consolidation exhibits a liver like echotexture. Abnormality in the chest x-ray revealed increased opacity that may be more gray or white and cotton wool like appearance. Pneumonic goats with reduced vitamin D concentration (group IIb)were also found to havealso revealed signiﬁcantly lower IgG and IgM concentrations in comparison to both group I and group II a. Vitamin D was positively correlated with IgG. Histopathologically, the pneumonic lesions include interstitial pneumonia, acute suppurative bronchopneumonia and acute fibrinous bronchopneumonia.
