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

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

鸡腹泻是鸡养殖过程中经常会出现的疾病,无论是哪个品种的鸡都有可能患该病.由于饲养过程中,部分养殖场的养殖环境不佳,造成鸡腹泻的患病概率增加.临床实践证明,鸡腹泻的类型种类比较多,诊治过程中还需结合具体病因选择合适的治疗办法,获得良好的治疗效果.基于此,本文对鸡常见腹泻的类型进行了分析,并提出了具体的诊治措施. 相似文献

1原因分析
引起鸡腹泻的病因主要是疾病,有时饲料营养成分搭配不当也会引起腹泻。除此之外,饲养管理不恰当也是引起腹泻的原因之一。 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
