瘤胃臌胀又叫瘤胃臌气,是反刍动物因采食大量多汁易发酵的饲料,形成大量的气体或泡沫而导致瘤胃迅速臌胀的急性疾病,临床上以突然发病,腹围急剧臌大,呼吸极度困难为特征。慢性瘤胃臌胀,多继发于前胃迟缓、瘤胃积食、瘤胃酸中毒、创伤性网胃炎等疾病的经过中。 相似文献

<正>瘤胃、瓣胃及网胃统称为前胃。前胃疾病是奶牛的常发病,在奶牛疾病中占很大比例。所以,防治前胃疾病对奶牛业的发展有重要意义。奶牛前胃疾病分为前胃迟缓、瘤胃积食、瘤胃臌气、创伤性网胃炎、瓣胃阻塞。前胃疾病除创伤性网胃炎外,在治 相似文献

断奶羔羊由于断奶应激的作用,很容易出现瘤胃疾病,以前胃迟缓、瘤胃积食、瘤胃鼓气、瘤胃炎等发病率最高,瘤胃微生态菌群失衡是该类疾病发生的最直接原因.病羊主要表现消化不良、采食下降、进行性消瘦以及瘤胃功能下降等.预防该类病应提升羊场管理水平,做好疫苗免疫,加强健康羊只的运动,定期使用微生态制剂.羔羊在引入后需有专人照料,只有科学地管理羊群,做到精心照料才能将羔羊疾病发生率降至最低. 相似文献

奶牛瘤胃酸中毒是奶牛常见的临床多发病,本病主要是因为奶牛采食大量谷类精饲料引起。常继发于奶牛瘤胃积食、前胃迟缓等病之后。笔者自2004年以来,采用中西药结合的办法,治疗153例,疗效显著。1病因1.1采食过量容易膨胀的精饲料,或者偷食大量玉米、小麦、大豆等豆谷类食物引起瘤胃积食,处理不当或者积食消除不及时继发瘤胃酸中毒。 相似文献

奶牛瘤胃积食瘤胃臌胀与瘤胃酸中毒的鉴别诊断 总被引：1，自引：0，他引：1
奶牛瘤胃积食、臌胀与酸中毒都是由于前胃机能障碍而引发的疾病,它们有许多相似之处。病牛瘤胃胀满,食欲减退或废绝,泌乳量显著减少,可视黏膜潮红或发绀,呼吸高度困难,心动增强,脉跳急速。瘤胃积食与臌胀的病牛,反刍、嗳气减少或停止,回视腹部,间或后肢踢腹。瘤胃蠕动先增强后减弱或消失。另外,瘤胃积食与臌胀也可继发于前胃弛缓、创伤性网胃炎、瓣胃阻塞疾病。它们的鉴别如下:1发病原因不同瘤胃积食是由于饲养管理不当,奶牛采食了大量的粗硬劣质饲料(如稻草、豆秸、玉米秸、花生蔓、甘薯藤等)或大量易膨胀的饲料所致。另外,饲养管理和卫生… 相似文献

瘤胃积食也称急性瘤胃扩张或者宿草不转,是瘤胃内滞积大量饲料,致使瘤胃异常充满,胃壁扩张,并伴有运动机能障碍的一种疾病,是牛羊等反当动物采食大量难消化、易膨胀的饲料,导致胃内积滞过多的粗饲料,从而引起胃体积增大,胃壁扩张,这种病症是牛羊最常见的疾病.文章从瘤胃积食的病因、瘤胃积食表现症状、瘤胃积食的治疗、牛羊瘤胃积食病的预防四个方面进行了综述. 相似文献

以国际标准强毒Ｒ株人工感染非免疫产蛋鸡,定时扑杀,分别从鼻窦、眶下孔、气管、肺、气囊、卵巢和输卵管分离ＭＧ,并收集感染鸡所产蛋分离ＭＧ。结果表明,人工感染４８小时后上、下呼吸道及肺已被全面感染,９６小时气囊已被感染,１２０小时输卵管已能分离到ＭＧ,卵巢始终分离不到ＭＧ。人工感染鸡自１４４小时便能在其所产蛋中分离出ＭＧ。药物治疗能在７２小时内消除感染,油乳剂苗则需２４天后逐渐降低蛋内ＭＧ分离率,药物卵内注射、种蛋药浴、高温处理均能杀死卵内ＭＧ,但以研制的种蛋浸泡剂药浴效果为最好。 相似文献

REASONS FOR PERFORMING STUDY: Centesis of the bicipital bursa using an 8.9 cm long spinal needle has been reported but the alternative of employing a 3.8 cm long hypodermic needle requires validation. OBJECTIVE: To compare the efficacy of 2 different methods of centesis of the bicipital bursa and to evaluate the usefulness of ultrasonographic imaging to determine the location of solution administered when centesis of the bursa is attempted. METHODS: For Trial 1, 6 clinicians, who had no previous experience of centesis of the bicipital bursa, attempted to inject a solution composed of an aqueous radiopaque contrast medium and physiological saline solution (PSS) into the bicipital bursae of 2/12 horses using the previously described distal approach to inject one bursa and a proximal approach to inject the contralateral bursa. The bicipital tendon and bursa were examined ultrasonographically before and after injection; and both shoulders were examined radiographically to identify the location of the medium. In Trial 2, another 6 clinicians, also with no previous experience of centesis, repeated Trial 1, using 6 horses, but the radiopaque contrast medium was mixed with air instead of PSS. RESULTS: Accuracy of centesis using the proximal approach was 39% and that of the distal approach 28%. Ultrasonographic examination of the shoulder allowed the location of solution and air to be accurately predicted in all 12 shoulders examined. CONCLUSIONS: Clinicians who have had no previous experience performing centesis of the bicipital bursa are unlikely to be successful in centesis using either approach. Radiographic examination after injecting a radiopaque contrast medium may be necessary to assess the success of centesis especially if bursal fluid is not obtained during centesis. Injecting air along with the radiopaque contrast medium provides more accurate ultrasonographic confirmation of centesis and better radiographic definition than does injection without air. 相似文献

Effects of size of ingestively masticated fragments of plant tissues on kinetics of digestion of NDF
Ingestively masticated fragments were collected and sized via sieving. Different sizes of esophageal masticate and ruminal digesta fragments, and ground fragments of larger masticated pieces were incubated in vitro, and undigested NDF remaining at intervals of up to 168 h of incubation was determined. The ruminal age-dependent time delay (tau) for onset of digestion of NDF was positively correlated (P < 0.004) with the mean sieve aperture estimated to retain 50% of the fragments between successive sieve apertures (MRA). Degradation rate of potentially degradable NDF (PDF) and level of indigestible NDF were not related (P > 0.10) to MRA of masticated and ground fragments. Estimates of tau were positively related to MRA, with slopes of bermudagrass < corn silage < ruminal fragments of corn silage. It was concluded that fragment size-, and consequently, ruminal age-dependent onset of PDF degradation of a mixture of different fragment sizes results in an age-dependent rate of degradation of the more rapidly degrading of two subentities of PDF. Models are proposed that assume a tau before onset of simultaneous degradation of PDF from two pools characterized as having gamma-modeled age-dependency and age-constant rates. The ruminal age-dependent pool seems to be associated with the faster-degrading pool, and its rate parameter increases with range in MRA in the population of fragments. Conceptually, the ruminal age-dependent rate parameter for PDF degradation seems to represent a composite of several effects: 1) effects of the size-dependent tau; 2) range in MRA of the population of ingestively masticated fragments; and 3) subentities of PDF that degrade via more rapid age-dependent rates compared with subentities of PDF that degrade via age-constant rates. The estimated fractional rates of ruminative comminution of ingestively masticated fragments (0.060 to 0.075/h) were of a magnitude similar to the mean fractional rates of PDF digestion (0.030 to 0.085/h), which implies that ruminative comminution may be first-limiting to fractional rate of PDF digestion. The in vivo roles of ingestive and ruminative mastication of fragments on PDF degradation must be considered in any kinetic system for estimating PDF digestion in the rumen. These results and others in the literature suggest that the rate of surface area exposure rather than intrinsic chemical attributes of PDF may be first-limiting to degradation rate of PDF in vivo. 相似文献
