猪流行性腹泻是由类冠状病毒引起的以胃肠病变为主的传染病。母猪的发病率为15%~90%,哺乳仔猪、架子猪或育肥猪的发病率可达100%。病的潜伏期,新生仔猪为24~36小时,育肥猪为2天。临床表现与猪传染性胃肠炎十分相似,大小猪均可发病,年龄越小,病情越重。粪便稀薄、呈水样,淡黄绿色或灰色,体温稍高或正常,精神、食欲变差。哺乳仔猪发病表现呕吐、水泻,肛门周围皮肤发红,1周龄内的仔猪常在水泻后3~4天因严重脱水而死亡;断奶后的仔猪与育肥猪的病程约持续1周左右。成年猪一般症状不明显,有时仅表现呕吐和厌食。主要病理变化是小肠绒毛萎缩,肠壁变薄呈半透明状,肠内容物呈水样。[防治措施](1)目前可利用细胞弱毒苗来预防,在母猪分娩前5周和2周,分别口服疫苗。母源抗体可保护仔猪4~5周龄内不发病。(2)对病猪用抗生素类药物治疗无效,但加强饲养管理,保持猪舍温暖、清洁、干燥,供足饮水可减轻病情和降低死亡率。

(1)营养和饲养管理引起的拉稀。这种腹泻常见的原因有十多种,如母猪的乳量不足,代乳料消化不良,维生素、矿物质缺乏,仔猪日粮中过量添加铜,饮水中金属离子超标,仔猪断奶、分群、转舍等应激性因素都能导致拉稀。(2)环境因素(物理因素)。如环境温度低等。(3)生理因素。如低血糖、消化不良等。(4)细菌引起的拉稀。常见有黄痢、白痢、红痢、副伤寒和痢疾等。(5)病毒引起的拉稀。常见有传染性胃肠炎、流行性腹泻、轮状病毒感染等。(6)寄生虫引起的拉稀。常见有线虫、绦虫、球虫等。扩展资料(1)提高猪舍温度(重点要提高仔猪腹部温度),搞好环境卫生,定期消毒,有效地消灭环境中的病原微生物是防止仔猪腹泻的关键。(2)科学饲养管理好母猪。对有寄生虫病的地区做好定期驱虫,防止通过母猪传染虫体。(3)做好母猪分娩前后的护理与防病。母猪于产前40天和15天各接种一次大肠杆菌苗。对有流行性腹泻或传染性胃肠炎发生的地区,可于产前20~30天注射流行性腹泻和传染性胃肠炎二联灭活苗一次。母猪进产房前,必须对产圈彻底清扫、冲洗和认真消毒;母猪做一次驱虫。母猪进入产房后和临产中,用温热的高锰酸钾液擦洗母猪的阴户、乳房。仔猪吃初乳前挤掉头两把奶,辅助初生仔猪尽早吃上吃好初乳,也是防止母猪乳房炎和仔猪腹泻的重要措施。(4)补充铁制剂。仔猪出生后3周内生长较快,每头仔猪每天约需3毫克铁,而母乳仅能提供1毫克铁,给出生3天和10天的仔猪人工补给含钴、硒的铁制剂,可防止仔猪缺铁性贫血造成的生长不良,增强仔猪体质,减少拉稀的发生。(5)提早补料。早补料可刺激胃肠发育,加强胃肠机能,有利于仔猪消化,提高饲料消化率,减少胃肠病。(6)猪抓好断奶关。仔猪断奶尽量减少刺激,断奶后7~10天仍保持用哺乳料,以后逐渐换料。(7)采取全进全出饲养方式,消除带菌猪,彻底消毒圈舍,净化养殖环境,有利于预防仔猪拉稀的发生。(8)药物预防。仔猪出生后用链霉素、庆大霉素、氟哌酸滴入2滴,1小时后再喂初乳,以消炎制菌,减少和防止仔猪的拉稀。

翻滚的小鱼人

猪拉稀的原因昨天,我们从猪的生理构造讲了猪为什么会拉稀。最近猪场猪仔拉稀腹泻的很多,今天我们就来聊聊遇到猪拉稀该怎么治?很多养殖户,现在越来越明白,养猪治病要先懂得猪为什么会生病,只有了解病因对症下药才能有效治愈,也更好的避免病情的反复。引起猪拉稀外部原因养殖户都知道:引起拉稀的外部原因是寒冷、潮湿、不卫生。1、寒冷刺激会诱发肠蠕动增加,导致猪非感染性腹泻。2、潮湿是一种变向的寒冷,因为猪接触水,水在蒸发时会吸收猪身体的热量,使猪局部变冷,从面引起拉稀。3、不卫生是因为猪容易吃进有害细菌,损害胃肠粘膜,从而引起拉稀。其实更为重要的原因可能是母猪奶水有毒,比如说脂肪性下痢,是因为奶水中有大量不能消化吸收的脂肪;母猪发生乳房炎时,奶水也是有毒的。引起猪拉稀内部原因引起拉稀的内部原因有以下几点。一是缺乏消化酶或激活的成分这主要是指哺乳仔猪断奶时的表现,这时的仔猪体内只有消化奶水的酶而没有消化固体饲料的酶,由奶水变成固体饲料,无法消化就会拉稀。第二种情况是胃肠道受损当猪胃肠道受损时,造成消化能力下降,饲料消化不彻底,也会引起拉稀第三种情况是炎症刺激,会加快排粪速度,吸收时间不足,也会拉稀。当猪发生胃溃疡,一定会伤到神经,肚子会疼,大脑认为是胃里的东西刺激的,就会下达命令,赶快把这些东西赶走,胃肠肌肉运动,营养来不及吸收就排出去了。遇到猪拉稀后怎么办?小猪拉稀造成的死亡率是相当高的,发现问题后必须马上采取措施。但关键是采取什么样的措施才能控制住,减少死亡。许多猪场拉稀死猪并不是他们不重视,而是方法不对。当遇到猪群拉稀时,先查病因,再对症治疗。如果是外界环境刺激,使猪发生应激可先改善猪舍内温度,卫生,保持干燥环境,然后用注射用头孢配合恩诺沙星注射液进行使用。遇到严重的拉稀,这时猪随时都会出现死亡,先要给猪补液,可以采用口服补液盐水的办法,必要的时候腹腔注射糖盐水,等猪稳定后,再进行下一步治疗。

一、选题选题是论文写作关键的第一步,直接关系论文的质量。常言说:“题好文一半”。对于临床护理人员来说,选择论文题目要注意以下几点:(1)要结合学习与工作实际,根据自己所熟悉的专业和研究兴趣,适当选择有理论和实践意义的课题;(2)论文写作选题宜小不宜大,只要在学术的某一领域或某一点上,有自己的一得之见,或成功的经验.或失败的教训,或新的观点和认识,言之有物,读之有益,就可以作为选题;(3)论文写作选题时要查看文献资料,既可了解别人对这个问题的研究达到什么程度,也可以借鉴人家对这个问题的研究成果。需要指出,论文写作选题与论文的标题既有关系又不是一回事。标题是在选题基础上拟定的,是选题的高度概括,但选题及写作不应受标题的限制,有时在写作过程中,选题未变,标题却几经修改变动。二、设计设计是在论文写作选题确定之后,进一步提出问题并计划出解决问题的初步方案,以便使科研和写作顺利进行。护理论文设计应包括以下几方面:(1)专业设计:是根据选题的需要及现有的技术条件所提出的研究方案;(2)统计学设计:是运用卫生统计学的方法所提出的统计学处理方案,这种设计对含有实验对比样本的护理论文的写作尤为重要;(3)写作设计:是为拟定提纲与执笔写作所考虑的初步方案。总之,设计是护理科研和论文写作的蓝图,没有“蓝图”就无法工作。
