四川鸽毛滴虫病的调查报告

鸽毛滴虫病是由鸽毛滴虫（Trichomonas columbae）寄生于鸽体内引起,根据其寄生部位不同分为咽喉型和内脏型。研究表明,约有80％的鸽带虫,成鸽多数呈带虫者,幼鸽病状明显。全国各地的养鸽场几乎都有该病的流行,但是鸽毛滴虫病在四川的流行情况尚无报道。     

雏鸽毛滴虫病的诊治体会

<正>鸽毛滴虫病又称鸽口腔溃疡,亦称为"鸽癀",是鸽的一种常见寄生虫病。鸽毛滴虫寄生于上消化道,引起口腔溃疡和坏死,使鸽因呼吸衰竭而死亡。该病主要危害幼(乳)鸽,能造成很高的死亡率。成年鸽往往带虫而不表现症状。(1)发病情况。5月15日晨,养鸽专业户李某繁育的部分15日龄雏鸽出现呼吸困难、少食甚至不食、嗉

鸽毛滴虫病的综合防治

鸽毛滴虫病是鸽最常见的一种传染性原虫病,鸽毛滴虫主要寄生在上消化道,温热潮湿天气更为多发;任何地方、品种、龄期的鸽子均会发病,是对养鸽业威胁最大的常见病之一。该病于1878年由Rirolta首次在鸽的小肠中发现,根据国外资料和国内的调查显示,约有80%的鸽带虫,成鸽的症状不明显,幼鸽症状表现突出,甚至死亡。带虫乳鸽即使发病轻微也影响营养吸收,品质下降,用药时又易出现药物残留,导致出口受阻,效益下降。此病必须引起高度重视。1.病原病原是属鞭毛亚门,动鞭毛纲,多鞭毛目,毛滴虫科,毛滴虫属的禽毛滴虫(Trichmonasgallinae)。虫体呈梨形、…     

鸽毛滴虫病

鸽毛滴虫病是鸽最常见的一种传染性原虫病,它主要寄生在鸽的消化道上,任何地方、品种、龄期的鸽子均会发病,是对养鸽业威胁最大的常见病之一。该病于1878年由Riroha首次在鸽的小肠中发现,根据国外资料和国内调查显示,约有80％的鸽带虫,成年鸽的症状不明显,青年鸽和幼鸽症状表现突出。青年鸽在育成过程中其死亡的鸽中70％以上是由此病引起,幼鸽通常因首次尝食成年鸽嗉囊中的“鸽乳”而被感染,并保持终生带虫。在形成足够保护力的免疫之前,受强毒虫株感染时,     

几种药物对鸽毛滴虫病的疗效试验

鸽毛滴虫是寄生在上消化道、对鸽危害较大的寄生原虫。不同品种与年龄的鸽几乎普遍带虫,它不仅可以引起幼鸽的发病和较严重的死亡,有时使正常的鸽呈现相当高的发病率,还可使未经免疫的鸽出现高达50%的致死率,给养鸽业造成一定的威胁。防治本病的药物,虽不断见有介绍,但鸽的饲料基本上仍用未经粉碎的作物原粒籽实料,不易混药,还有不少药物水溶性较差,药物来源不易解决的问题,给防治工作带来     

信鸽球虫病的诊治

一起肉食鸽蛔虫病的诊断与防治

<正>蛔虫病是鸽常见的寄生虫病。鸽蛔虫是鸽中最大的寄生线虫,属禽蛔科、禽蛔属,虫体长20～50mm,虫卵呈椭圆形,随粪便排出。鸽子通常因为吞吃含有感染性虫卵的饲料、饮水和保键砂而被感染。成年鸽往往是带虫者,3月龄以内幼鸽病情较为严重,生长发育受阻,严重的可导致死亡。我县五汛镇农户王某饲养的200只肉食鸽发生该病,经笔者诊治,取得了满意效果。现将其介绍如下。
