Doenças do sistema digestório de caprinos e ovinos no Semiárido do Brasil.

Abstract

This papers reports the diseases of the digestive system of sheep and goats in the semiarid of Brazil (Chapter I) and a case of vagus indigestion in goat (Chapter II). The records of the diseases of goats and sheep treated at the Medical Clinic of Large Animals (CMGA) were reviewed, as well those from the Laboratory of Animal Pathology from the Veterinary Hospital of Federal University of Campina Grande .from January 2000 to December 2011. A total of 2.144 attendances were recorded in small ruminants. 512 cases (23,9%) were diagnosed as digestive disease, 367 (71,7%) occurred in goats and 145 (28,3%) in sheep. Gastrointestinal helminthosis and coccidiosis were the diseases most frequently diagnosed, 330 cases being recorded. The disorders of the cavity ruminoreticular (acidosis ruminal, simple indigestion, bloat and ruminal compaction) totaled 94 (18,4%) cases. The abomasum was affected by primary and secondary ulcers, cases of obstruction and compression of the gastrointestinal tract were also observed. Malformations, such as anal atresia and cleft palate, were recorded in both species and were associated with intoxication by Mimosa tenuiflora (jurema preta). Among the infectious diseases five cases of contagious ecthyma, two cases of paratuberculosis and two cases of gastrointestinal pythiosis were diagnosed. In seven cases (1,4%) the suspected disease were enterotoxemia and in 31 cases (6%) the diagnose was enteritis nonspecific. The lack of an integrated control of parasites and the use of inadequate foods during the period of scarcity of forage contributes to the occurrence of a great number of diseases. For the case report of the motor disorder were described clinical signs, findings observed in an exploratory laparorrumenotomy and necropsy. The clinical signs were lethargy, weight loss, dehydration, bradycardia, ruminal distention and hypermotility. In the laparorrumenotomy and necropsy were visualized adhesions between organs and abscesses that suggest that branches of the vagus nerves were involved in the inflammatory process and caused a disturbance similar to Hoflund syndrome in bovine.
