羊瘤胃鼓气发病机理、症状及治疗

Pathogenesis,Symptoms and Treatment of Rumen Bloating in Sheep

羊瘤胃鼓气又被称为羊瘤胃鼓胀,是因为羊采食较多容易产生气体或容易发酵的饲料,使瘤胃中的内容物集聚发酵产生气体,气体增多后影响瘤胃的正常蠕动,瘤胃体积显著膨大,腹部维度突出,呼吸困难为主要特征的一种胃部疾病。该种疾病的发生流行具有一定季节性,常发生在春季牧草刚生长出来和秋季牧草结籽时期。放牧养殖比舍饲养殖的羊群更容易出现该种疾病。羊瘤胃鼓气发病过程较短,发病急,发生后,如果不能及时判定发病原因,及时采取措施诊疗,容易错过最佳治疗时机,造成患病羊临床症状加重,进而引发窒息死亡,给养殖场带来不可挽回的经济损失。该文主要探讨羊瘤胃鼓气的发病机理、临床症状和治疗措施。

Rumen bloating in sheep is also called rumen bloating in sheep because the sheep take more feed which is easy to produce gas or easily fermented feed,which makes the rumen contents concentrate and ferment to produce gas,and the increase of gas affects the normal peristalsis of rumen,a stomach disease characterized by marked enlargement of the rumen,prominent abdominal dimensions,and dyspnea.The occurrence and prevalence of the disease is seasonal,often occurring in the spring when the grass is just growing out and in the autumn when the grass is setting seeds.The disease is more likely to occur in grazing than barn-raised sheep.The process of rumen bloating in sheep is relatively short and the onset is acute.If the causes of the disease can not be determined in time and measures are taken in time for diagnosis and treatment,it is easy to miss the best time for treatment,resulting in an aggravation of the clinical symptoms of the infected sheep,thus leading to asphyxia and death,bring irretrievable economic loss to the farm.This article mainly discusses the pathogenesis,clinical symptoms and treatment of rumen bloating in sheep.
