ABSTRACT.
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.
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. MenosABSTRACT.

Silvopasture systems combine trees, forage, and livestock in a variety of different species and management regimes, depending on the biophysical, economic, cultural, and market factors in a region. We describe and compare actual farm practices and current research trials of silvopastoral systems in eight regions within seven countries of the world: Misiones and Corrientes provinces, Argentina; La Pampa province, Argentina; northwestern Minas Gerais, Brazil; the Ayse´n region of Patagonia, Chile; the North Island of New Zealand; the Southeast United States; Paraguay; and Uruguay. Some countries use native trees and existing forests; some use plantations, particularly of exotic species. Natural forest silvopasture systems generally add livestock in extensive systems, to capture the benefits of shade, forage, and income
diversification without much added inputs. Plantation forest systems are more purposive and intensive, with more focus on joint production and profits, for small
owners, large ranches, and timber companies. Trends suggest that more active management of both natural and planted silvopastoral systems will be required to
enhance joint production of timber and livestock, achieve income diversification and reduce financial risk, makemore profit, improve environmental benefits,
and realize more resilience to adapt to climate change. |
