猪无名高热即“猪高热综合征”，是一种发病率和死亡率均较高的疾病，主要发生于育成猪和部分母猪。病猪临床主要表现为体温升高、精神沉郁、食欲不振或废绝、呼吸困难、喘气，部分病猪伴有皮肤发红、变紫等症状，少数病猪毛孔有出血点。 相似文献

为探讨猪常见高热性传染病的治疗效果。方法 选取2022年7月～2023年1月某猪养殖场78头感染猪流感的病猪展开研究，运用随机数字法将研究样本分为两组，分别为常规组（n=39）与联合组（n=39），常规组病猪给予西药治疗，联合组在西药基础上联合中药展开治疗，对比两组病猪各症状消失时间。结果中，联合组病猪呼吸恢复正常时间为（1.42±0.25）d、食欲恢复时间为（3.17±0.58）d、关节酸痛症状消失时间为（3.12±0.58）d、咳嗽消失时间为（3.01±0.26）d、体温恢复正常时间为（2.47±0.23）d，均明显短于常规组，差异具有统计学意义（P <0.05）。得出结论，在猪养殖过程中，各种高热性传染病均较为常见，养殖人员应明确各种高热性传染病的病因、症状及预防方式，在猪感染高热性传染病后可采用中西药联合方式对病猪进行治疗，缩短病猪症状消失时间，促进病猪康复，保障养殖效益。 相似文献

集约化养殖户与个体养殖户的猪群,一旦发生疑似猪瘟、猪丹毒、猪胃肠炎、猪流行性腹泻、猪肺疫、猪伪狂犬病、猪蓝耳病等多种瘟疫时,往往表现高热症状,但因这些疫病在临床上很难通过肉眼分辨清楚,即使将病猪待检病料送往动物传染病诊断化验室,也需3～30天才能检测出可能是哪几种传染病原的疑似结果,等搞清病原,病猪群有可能存亡难卜,应用猪用抗多病免疫球蛋白能解决燃眉之急,但在临床上还要了解免疫球蛋白的治疗机理,使用合理时才能真正发挥免疫球蛋白的可靠性能。同时也要掌握如何才能使病猪血液中的免疫球蛋白在48小时左右保持最高浓度。… 相似文献

＂猪无名高热＂即猪高热综合征,是一种发病率和死亡率均较高的疾病,主要发生在育成期猪和部分母猪。病猪临床主要表现为体温升高、精神沉郁、食欲不振或废绝,呼吸困难、喘气,部分猪伴有皮肤发红变紫等症状,少数毛孔有出血点。猪的无名高热病在现代养猪业中发生频繁、该病单纯用西医的治疗方法治愈率很低。笔者用中西医结合的方法治疗发病猪46头,治愈44头,治疗效果理想。 相似文献

近年来,猪高热病在东北地区不断发生,由于养殖户对本病缺乏了解,为了减轻经济损失,常在治疗2次效果不佳后把病猪淘汰.其实高热性病的致死率并不高,只要方法得当多数病猪都能医治.
1发病情况
据调查,2006年以来,黑龙江省部分地区陆续发现猪高热病,患猪共同特征是持续高热,发病猪年龄大小不一,1月龄以内猪发病率最高,死亡率为80%～90%;2～3月龄病猪死亡率为50%～60%;4月龄以上的死亡率为14%;母猪也有发生,但应用大量抗生素治疗,并紧急接种疫苗,90%病猪有可能康复. 相似文献

Efficacy of tulathromycin injectable solution for the treatment of naturally occurring Swine respiratory disease 总被引：4，自引：0，他引：4
Nutsch RG Hart FJ Rooney KA Weigel DJ Kilgore WR Skogerboe TL 《Veterinary therapeutics : research in applied veterinary medicine》2005,6(2):214-224
Tulathromycin, a novel triamilide antimicrobial, was evaluated for treatment of swine respiratory disease (SRD) in field efficacy studies involving 720 pigs in six North American swine herds. In each study, feeder pigs with clinical SRD were randomly assigned in equal numbers to a group treated with tulathromycin given as a single injection at 2.5 mg/kg of body weight or to a saline-treated control group. Four of the studies included a third group treated with ceftiofur sodium for 3 consecutive days at 3 mg/kg of body weight. Pigs were treated on day 0 and evaluated for treatment response on day 7. In each study, 10 or more nontreated pigs and saline-treated pigs that did not respond to treatment underwent necropsies to obtain lung samples that were evaluated for SRD pathogens. The overall cure rate was 46.4% for saline-treated pigs, 71.1% for tulathromycin-treated pigs, and 63.1% for ceftiofur-treated pigs. The cure rate for tulathromycin-treated pigs was significantly higher than for saline-treated pigs (P = .0116). Mortality from SRD occurred in 24 control pigs, seven tulathromycin-treated pigs, and one ceftiofur-treated pig. The mortality rate was significantly lower for both the tulathromycin- and ceftiofur-treated pigs compared with those treated with saline (P = .0148 and P = .0195, respectively). Actinobacillus pleuropneumoniae, Pasteurella multocida, Haemophilus parasuis, and Mycoplasma hyopneumoniae, bacteria commonly associated with SRD, were isolated from SRD-affected pigs. Under field conditions, tulathromycin injectable solution given as a single IM dose of 2.5 mg/kg of body weight was safe and effective in the treatment of SRD. 相似文献

规模化种猪场猪瘟免疫情况调研 总被引：3，自引：0，他引：3
猪瘟是由猪瘟病毒引起的一种以高热、出血为主要特征的烈性、高度接触性传染病,至今仍在中国广泛流行。接种疫苗是防控该病发生的最根本的方法,为了查清山西省规模化种猪场猪瘟疫苗免疫情况,课题组采用ELISA试剂盒,对8个地市42个规模化种猪场465头哺乳猪、456头保育猪、436头育肥猪、419头母猪进行了猪瘟免疫抗体检测。查明了哺乳猪抗体阳性率平均为70.11%,保育猪抗体阳性率平均为40.57%,育肥猪抗体阳性率平均为50.22%,母猪抗体阳性率平均为69.69%,证明被检猪群免疫抗体不理想,尤其是保育猪抗体水平较低。同时对12个规模化种猪场,4类不同免疫方法免疫猪瘟疫苗的133头哺乳猪、110头保育猪、105头育肥猪、135头母猪进行了免疫抗体检测。结果表明:乳猪在吃奶前超免猪瘟高效细胞苗6头份,21日龄时二免猪瘟高效细胞苗4头份,60日龄三免猪瘟高效细胞苗2头份,母猪产后21 d跟胎免疫效果最好,使保育猪免疫抗体阳性率达到89.29%,有些猪场使用该方法免疫后,使保育猪的死亡率有了明显的降低,生长发育逐渐走向正常;而采用仔猪在断奶后28日龄至35日龄时首免猪瘟普通细胞苗4头份,60日龄二免猪瘟普通细胞苗2头份,母猪产后28 d跟胎免疫的方法效果最差,不宜推广应用。通过对山西一些规模化种猪场猪瘟免疫情况的调研,基本查清了规模化种猪场猪瘟免疫效果和最佳免疫方法,可为养猪场防控猪瘟提供依据。 相似文献

A cohort of 53 swine seronegative to Aujeszky's disease virus (ADV) was monitored in a 1 year study of a chronically infected commercial Swedish weaner pig producing herd. Serum samples were acquired from all 134 adult swine and analyzed by enzyme-linked immmunosorbent assay (ELISA). Animals testing negative, along with introduced replacement gilts, were followed serologically every second month. Movements of animals were recorded for 319 days and exposure to seropositive animals was calculated for each seronegative pig in the cohort. The accumulated daily pig contact between the 53 ADV-non-infected swine and 43 infected swine was 35 660 days and the median number of days in contact for the non-infected swine with infected was 222. Despite the frequent contact with seropositive pigs, no seronegative animals seroconverted during the first 11 months of observation. Forty-six of 53 pigs seroconverted after a clinical outbreak during the twelfth month of observation. 相似文献

重组白细胞介素-2提高PRRS抗体阳性猪的猪瘟疫苗免疫效果试验 总被引：6，自引：2，他引：6
观察了重组白细胞介素-2（IL-2）对健康成年猪和PRRS抗体阳性猪的猪瘟疫苗免疫效果的影响。结果显示,重组IL-2和猪瘟疫苗一起免疫健康猪,20d后间接血凝抗体滴度达到1∶64的猪的比例为87.5％,而不注射IL-2的对照组抗体滴度可以达到这一水平的比例只有25％。给经2次猪瘟疫苗免疫但抗体滴度在1∶32以下的PRRS抗体阳性猪单独注射IL-2,20d后,注射前检测不到抗体的猪都检测到了抗体,注射前抗体滴度在1∶8～1∶16之间的猪的抗体滴度提高到1∶32～1∶64。再次用猪瘟疫苗和IL-2共同免疫,可使抗体滴度提高4倍以上。而不注射的对照组抗体滴度则略有下降。说明重组IL-2可以减轻PRRS感染所引起的免疫抑制,提高猪瘟疫苗的免疫效果。 相似文献

The efficacy of a Bordetella bronchiseptica bacterin was evaluated in 2 commercial swine herds affected with mild and severe enzootic atrophic rhinitis (AR). In the 1st herd study, (mild AR), the degree of clinical AR, nasal turbinate evaluation, blood serum titer to B bronchiseptica antigen, and adjusted days from birth to 100 kg were determined for individual pigs. Bacterin inoculation reduced the incidence and severity of gross turbinate atrophy 57% and reduced clinical AR over 93%. Inoculated swine had an average blood serum-agglutinating titer greater than 1:2,793 and noninoculated (control) swine had an average titer of 1:112. Increased serum titer significantly (P less than 0.05) correlated with decreased degree of nasal turbinate atrophy. Inoculated and control pigs reached 100 kg in an average of 171 and 178 days after birth, respectively. In the 2nd study (severe enzootic AR), inoculated and control pigs were individually evaluated for clinical AR and total average daily weight gain. Inoculation reduced clinical AR over 90%. The total average daily gain for the inoculated and control pits was 435.84 g and 340.50 g, respectively. Inoculated pigs and control pigs reached 100-kg market weight in 184 and 238 days, respectively. 相似文献

During 3 trials, using affected pigs of various ages, tiamulin was evaluated for treatment of experimentally induced mycoplasmal pneumonia. Pneumonia was induced in respiratory tract disease-free swine by intratracheal inoculation of a lung homogenate containing Mycoplasma hyopneumoniae. Eleven days after inoculation, when more than 20% of pigs were coughing, pigs were allotted to 3 or 4 groups (n = 8 pigs each) and were given regimens of no medication or 60 mg, 120 mg, or 180 mg of tiamulin/L of drinking water for 10 days. Twenty-one days after cessation of medication, pigs were euthanatized and then were necropsied. Results obtained from the 3 trials did not indicate significant difference among treatment groups in severity of macroscopic or microscopic lesions induced by M hyopneumoniae or in detection of M hyopneumoniae by use of immunofluorescent technique. Clinical evaluations, daily gain, and feed efficiency did not differ significantly among treatment groups. In this study, tiamulin administration did not have beneficial effects in swine with mycoplasmal pneumonia. 相似文献

This study characterizes the clinical response and colonization pattern of caesarean-derived, colostrum-deprived swine exposed to a delta cya/delta crp mutant (chi 4233) of S. typhimurium and challenged with the wild-type parent strain. chi 4233 was mildly virulent in swine and induced transient fever and soft stools. Chi 4233 colonized the ileum, cecum, liver, spleen, tonsils, and mandibular and ileocolic lymph nodes of swine in a manner similar to the parental wild-type, but the numbers of S. typhimurium (chi 4233) in the ileum were 100- to 1000-fold less than those of pigs exposed to the parental wild-type. Pigs exposed to chi 4233 21 days before parental wild-type challenge demonstrated a milder clinical response to challenge than did pigs that did not receive chi 4233. The wild-type populations in the ilea of chi 4233-exposed pigs after challenge were 100- to 10,000-fold less than those in pigs not receiving chi 4233. The liver, spleen, and ileocolic lymph nodes were cleared of wild-type S. typhimurium more quickly after challenge in chi 4233-exposed pigs. The populations of chi 4233 in the ilea of exposed pigs after wild-type challenge were also less than would have been expected in unchallenged pigs. Thus, exposure of swine to a delta cya/delta crp mutant of S. typhimurium modulated the subsequent response to parental wild-type challenge and reduced carrier populations of wild-type S. typhimurium in infected swine. 相似文献
