Occurrence of acid erosion of the teeth, actinomycosis and polioencephalomalacia in flock of sheep fed wet low pectin citrus pulp

ABSTRACT: The citrus pulp can be used as a substitute in ruminant feed reducing costs and maintaining the nutritional quality of food. However, this compound should be used carefully so as not to cause harm to the animals. The present report aims to describe the occurrence of dental erosion, actinomycosis and polioencephalomalacia in sheep raised and kept with a wet low pectin citrus pulp based diet, composing 50% of roughage. Actinomycosis was diagnosed in five animals through clinical and radiographic examinations and microbiological culture, and, after treatment, three animals were cured. Polioencephalomalacia was confirmed in ten animals by clinical diagnostics, in nine out of ten animals by therapeutic diagnosis, and in one animal by post-mortem anatomopathological examination. According to the observed, we recommend caution when large amounts of citrus pulp are used as bulky food.

摘要：柑橘果渣（citrus pulp）可作为反刍动物饲料的替代原料，在降低饲养成本的同时保障饲料的营养品质。但该原料需谨慎使用，以免对动物造成健康损害。本报告旨在描述饲喂以占粗饲料比例50%的低果胶湿型柑橘果渣为日粮组成部分的绵羊所发生的牙侵蚀症、放线菌病及脑灰质软化症的发病情况。通过临床检查、放射影像学检查及微生物培养，确诊5只绵羊患有放线菌病；经治疗后，其中3只痊愈。脑灰质软化症的确诊情况如下：10只绵羊经临床诊断确诊，10只中的9只经治疗性诊断确诊，另有1只通过死后解剖病理检查确诊。基于上述观察结果，我们建议在以大量柑橘果渣作为粗饲料时需格外谨慎。
