Abstract

Mycoplasma hyopneumoniae (MHP) infection occurs globally and contributes to economic losses. Acute infections occur in immunologically naive populations affecting pigs of all ages and causing clinical signs including fever, coughing, acute respiratory distress, and death. An acute MHP infection was investigated in a naive 4200-sow breed-to-wean herd. An increase in sow mortality (4.16%, 8.33%, and 3.89%) and preweaning mortality (10.45%, 12.38%, and 12.06%) occurred when comparing the naive, acute infection, and post-infection periods, respectively. Further production differences included 166.3, 158.3, and 164.2 kg weaned/sow/year and 29.43, 28.35, and 28.28 pigs weaned/mated female/year in naive, acute infection, and post-infection periods, respectively.

急性肺炎支原体感染在未出生的种猪到断奶的牛群

肺炎支原体(MHP)感染在全球范围内发生，并造成经济损失。急性感染发生在未免疫的猪群中，影响所有年龄的猪，并引起临床症状，包括发烧、咳嗽、急性呼吸窘迫和死亡。在一个4200头从种到断奶的母猪群中调查了急性MHP感染。与初感染期、急性感染期和感染后期相比，母猪死亡率分别增加了4.16%、8.33%和3.89%，断奶前死亡率分别增加了10.45%、12.38%和12.06%。在初感染期、急性感染期和感染后，每头母猪断奶体重分别为166.3、158.3和164.2公斤/年，每头交配母猪断奶体重分别为29.43、28.35和28.28公斤/年。

期刊介绍： The Journal of Swine Health & Production (JSHAP) is an open-access and peer-reviewed journal published by the American Association of Swine Veterinarians (AASV) since 1993. The aim of the journal is the timely publication of peer-reviewed papers with a scope that encompasses the many domains of applied swine health and production, including the diagnosis, treatment, management, prevention and eradication of swine diseases, welfare & behavior, nutrition, public health, epidemiology, food safety, biosecurity, pharmaceuticals, antimicrobial use and resistance, reproduction, growth, systems flow, economics, and facility design. The journal provides a platform for researchers, veterinary practitioners, academics, and students to share their work with an international audience. The journal publishes information that contains an applied and practical focus and presents scientific information that is accessible to the busy veterinary practitioner as well as to the research and academic community. Hence, manuscripts with an applied focus are considered for publication, and the journal publishes original research, brief communications, case reports/series, literature reviews, commentaries, diagnostic notes, production tools, and practice tips. All manuscripts submitted to the Journal of Swine Health & Production are peer-reviewed.
