Diagnosis and treatment of foreign bodies swallowing syndrome in camels (Camelus dromedarius) with special reference to the role of mineral deficiency

Abstract

This study describes the clinical presentation of ruminal and reticular foreign body syndrome (RRFBS), and evaluates the effect of mineral deficiency on its occurrence in dromedary camels. Thirty dromedary camels were divided into two groups. Group 1 (control) included 10 apparently healthy she-camels. Group 2 consisted of twenty dromedary camels diagnosed with RRFBS on the basis of clinical, ultrasonographic, hematological, and biochemical examinations. Clinical findings showed decreased appetite and milk yield, tympany, and gradual body weight loss. Ultrasonographic examinations revealed the presence of hyperechoic material with variable degrees of shadowing. Hematological evaluation showed a significant (P<0.05) decrease of the total erythrocyte and lymphocyte count and a significant increase of neutrophils in the camels with RRFBS compared to the controls. Biochemical tests showed a significant elevation in the activity of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), creatine kinase (CK), glucose, creatinine, and blood urea nitrogen and a significant decrease of sodium, chloride, potassium, cobalt, iron, and selenium in the camels with RRFBS compared to the controls. Rumenotomy was performed on the 20 camels as a surgical intervention for treating the RRFBS. By the 6th month postoperatively, all surgically treated camels had completely recovered except for one with tympany and slight swelling in situ. In conclusion, trace element deficiency might play an important role in the occurrence of foreign body ingestion syndrome in dromedary camels. Moreover, clinical, ultrasonographic, hematological, and biochemical examinations are considered as tools assisting in the accurate diagnosis, prognosis, and treatment stratagem for RRFBS in camels.
