Conteúdo: | Indigestion due to compaction of the ruminal content is a digestive disorder resulting from low-quality forage intake, rich in lignin and with low levels of energy and digestible protein, with or without water restriction. The accumulation of plant residues rich in indigestible fibers can also lead to formation of phytobezoars, causing digestive disorders and intestinal obstructions. The objective of this paper was to describe the epidemiology and the clinical and pathological changes of an outbreak of indigestion and other digestive disorders in cattle fed Agave sisalana. The affected herd consisted of 22 adult cattle reared in a semi-extensive system, which ingested almost exclusively stalks of A. sisalana manually cut for two months. Six cows showed decreased appetite and rumination, abdominal distension, and reduced production of dried feces. One animal was referred to the Veterinary Hospital. The presumptive diagnosis of indigestion was made by the epidemiologic data, clinical signs, and laboratory evaluation. At necropsy, the rumen, reticulum and omasum were filled with fibrous and dried A. sisalana content. A viscous, greenish brownish content was present in the abomasum. Numerous phytobezoars were found in the pre-stomachs and abomasum measuring 4-12cm in diameter. One phytobezoar was partially obstructing the duodenum, with the cranial part of the organ filled with intestinal content, and the caudal portion was empty. It is concluded that the administration of A. sisalana stalks for long periods may cause indigestion due to ruminal compaction and formation of phytobezoars.
