ABSTRACT.- Nascimento E.M., Medeiros R.M.T., Simões S.V.D. & Riet-Correa F. 2016. [Ruminal indigestion and intestinal obstruction in cattle associated with consumption of Agave sisalana Perrine.] Compactação ruminal e obstrução intestinal em bovinos, associadas ao consumo de Agave sisalana Perrine (Agavaceae). Pesquisa Veterinária Brasileira 36(8):719-723. Hospital Veterinário, Faculdade de Veterinária, Universidade Federal de Campina Grande, Av. Universitária s/n, Patos, PB 58708-110, Brazil. E-mail: eduardoaquario@hotmail.com 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.

RESUMO.- Nascimento E.M., Medeiros R.M.T., Simões S.V.D. & Riet-Correa F. 2016. [Ruminal indigestion and intestinal obstruction in cattle associated with consumption of Agave sisalana Perrine.] Compactação ruminal e obstrução intestinal em bovinos, associadas ao consumo de Agave sisalana Perrine (Agavaceae).

E-mail: eduardoaquario@hotmail.com A compactação dos pré-estômagos é um transtorno digestivo resultante da ingestão de forragem de baixa qualidade, rico em lignina e com baixos níveis de energia e proteína digerível, associada ou não a restrição hídrica. O acúmulo de vegetais ricos em fibras indigeríveis pode levar também a formação de fitobezoares, causando transtornos digestivos e obstruções intestinais. Objetivou-se com este trabalho descrever os aspectos epidemiológicos e as alterações clínico-patológicas de um surto de alterações digestórias em bovinos alimentados com Agave sisalana. O rebanho acometido era formado por 22 animais adultos, criados de forma semiextensiva, que, devido a escassez de forragem, receberam no cocho, quase que exclusivamente, durante dois meses, o caule do A. sisalana cortado manualmente. Seis vacas apresentaram diminuição do apetite, distensão abdominal, redução dos períodos de ruminação e da produção de fezes. Um animal foi encaminhado ao Hospital Veterinário da Universidade Federal de Campina Grande. O diagnóstico presuntivo de compactação ruminal e obstrução intestinal foi dado pela epidemiologia, sinais clínicos e análise de fluido ruminal. Na necropsia observou-se rúmen, retículo e omaso repletos, com conteúdo fibroso e ressecado constituído por fibras de A. sisalana. No abomaso observou-se a presença de conteúdo pastoso e esverdeado a acastanhado. Em todos os pré-estômagos e no abomaso havia fitobezoares, que mediam entre 4 e 12 cm de diâmetro. No duodeno um fitobezoar obstruía parcialmente a luz do órgão, com a porção anterior repleta de conteúdo e a posterior vazia. Conclui-se que a alimentação com caules de A. sisalana por longos períodos causa compactação de pre-estômagos e formação de fitobezoares.


#2 - Compactação primária do abomaso em 14 bovinos no Estado de Pernambuco, p.387-394

ABSTRACT.- Câmara A.C.L., Afonso J.A.B., Costa N.A., Mendonça C.L. & Souza M.I. 2009. [Primary abomasal impaction in 14 cattle from Pernambuco State, northeastern Brazil.] Compactação primária do abomaso em 14 bovinos no Estado de Pernambuco.

Postal 152, Mundaú, Garanhuns, PE 55292-901, Brazil. E-mail: aclcamara@yahoo.com.br Despite the frequent use of dry and fibrous roughage for feeding cows in many regions, especially during the dry season, impaction of the abomasum has been poorly reported in Brazil, probably because the condition is misdiagnosed by practitioners. The present paper aimed to accomplish a retrospective study on primary abomasal impaction in 14 cattle from Pernambuco State, northeastern Brazil. Eight moderate cases, without severe abdominal distention and with no rumen compaction, were treated conservatively, and four severe cases, with severe abdominal distention and rumen compaction, were treated surgically. One bull was slaughtered and one cow died without treatment. The greater number of abomasal impaction cases was in Holstein cows with six cases (42.9%), followed by crossbred cattle with five cases (35.8%), and the breeds Brown-Swiss, Nelore and Marchigiana, each with one case (21.3%). The food composition was characterized by low quality fibers and varied greatly among cases. Most frequent clinical signs were apathy, dehydration, hypomotility and ruminal bloat, intestinal hypomotility and scanty or absent feces with mucus. The hematological findings revealed leukocytosis with neutrophilia and hyperfibrinogenemia in most cases. Ruminal fluid analysis showed compromised flora and fauna dynamics and increased chlorine ion concentration. Clinical (4/8) and chirurgical (2/4) recovery rate achieved 50%. The clinical and chirurgical methods remain as viable options for the treatment of light and severe impaction, but the prognosis is always reserved especially when associated to late pregnancy.
