鸡腹泻是由多种原因引起的,以拉稀粪或水样粪便为特点的多种疾病的总称。本病为常发病多发病。由于病因复杂,常给临床治疗带来许多困难。欲防治该病,关键是弄清导致腹泻原因。鉴于此,笔者分析了近3年来兽医门诊就医病例,并走访部分养鸡场(户),针对鸡腹泻的原因进行初步的调查,现归纳如下:1细菌感染肠道细菌感染是引起腹泻的主要原因。凡是寄生在肠道内,引起肠道吸收功能紊乱的细菌均能导致腹泻的发生。常见的有大肠杆菌病、鸡白痢、禽伤寒、禽副伤寒、禽霍乱、溃疡性肠炎、坏死性肠炎等;另外还有链球菌病、绿脓杆菌病、丹毒、伪结核病、禽肠…  相似文献

正仔猪腹泻是养猪场户常见的一种多病因疾病,也是引起仔猪死亡的主要原因,严重威胁着养猪业的健康发展。该病能够导致饲料报酬率较低、仔猪成活率下降、生长缓慢、生长发育停滞(即僵猪)。由于引起该病发生的病因复杂,常表现为多种因素相互作用,呈交叉混合感染,导致临床诊断与防治困难。治疗仔猪腹泻,只有找出病因、消除病因、并加以对症治疗,才能标本兼治。  相似文献

鸡传染性腺胃炎是一种由多种原因引起的鸡腺胃综合征,主要以鸡的生长缓慢或阻滞、腺胃肿大充血、腺胃乳头出血、溃疡甚至糜烂为特征的传染性疾病。鸡传染性腺胃炎的病原较复杂,可能主要有禽网状内皮组织增殖病病毒、冠状病毒、鸡痘病毒及霉菌毒素等构成。一般认为该病的发生由病毒、霉菌及细菌等多种因素协同作用。由于病因尚无定论,加之该病防制困难,给养禽业造成了重大的经济损失。文章就鸡传染性腺胃炎几个主要的发病原因进行分析和叙述。  相似文献

鸡腹泻是由多种病因引起的一个共同症状,常见的有:胃肠道疾病、消化不良、大肠杆菌病、寄生虫病以及霉变饲料中毒等。对于鸡腹泻的治疗,除对症选用抗菌素、磺胺类等抑菌消炎药物外,还可以采用中药治疗。尤其是对不明原因引起的腹泻。笔者在临床工作中,根据中兽医辩证施治原则,试用中草药防治该病效果明显。现将情况介绍如下供参考。1中药配方和用法苍术50g,厚朴、白术、干姜、肉桂、柴胡、白芍、胆草、黄芩、十大功劳各25g木炭100g共研末混匀。大鸡3~5g、小鸡1~3g,每日2次,混料内服,对已严重不吃食的鸡应加温水灌服。如作为预防剂量减半,…  相似文献

仔猪腹泻是仔猪最常见的疾病,不仅给养猪业带来直接的经济损失,还间接的影响到病愈猪的生长发育。虽然我国已研制出多种防制仔猪腹泻的生物菌苗,应用后也有一定的预防效果,但由于该病病因的多样性,各猪场的防治体系又不尽完善,所以一直无法根治该病,本人经多年的经验对该病的发生原因及综合防治作如下阐述:  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

乳酸杆菌益生作用机制的研究进展   总被引:2,自引:0,他引:2  
乳酸杆菌作为益生菌广泛用于人和动物。本文综述了乳酸杆菌改善宿主健康的机制。乳酸杆菌可通过产生抗菌物质如乳酸、过氧化氢、细菌素,或者通过竞争营养或肠道黏附位点来抑制致病菌;通过诱导黏附素的分泌或阻止细胞凋亡而增强肠道的屏障功能,从而保护肠道。文章重点讨论了乳酸杆菌表面成分(表面蛋白、脂磷壁酸和肽聚糖)与肠道受体(C型凝集素受体、Toll样受体和 Nod样受体),阐述了他们结合后启动免疫调节信号,调控肠道免疫功能以发挥改善健康作用的机制。  相似文献

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
