Concise summaries of published swine health and production research, organized for quick discovery.
In a Quebec-tailored life-cycle assessment, precision feeding reduced modeled climate, acidification, and eutrophication impacts compared with conventional three-phase feeding.
PPV2 was common in lungs from Colombian pigs, but coinfections predominated and direct localization in lesions was uncommon, so detection did not establish causation.
Across three commercial farms, a bivalent PCV2d–M. hyopneumoniae vaccine improved ADG and several health indicators compared with unvaccinated controls.
Landrace pig T-lymphoblasts were more permissive to PCV2 than Piétrain cells, with endolysosomal trafficking differences that may contribute to cellular susceptibility.
In an experimental trial involving ten SPF miniature pigs, a PCV2d virus-like-particle vaccine markedly reduced viral detection after challenge, but farm effectiveness remains unproven.
Among apparently healthy slaughter pigs in Thailand, S. suis was common and genetically diverse, but molecular markers did not perfectly distinguish commensal from pathogenic strains.
Genomic and phenotypic analysis of S. suis serotype 4 found potentially pathogenic lineages and extensive multidrug resistance, without implying equal risk from every isolate.
In a mouse model of S. suis, T-cell-dependent IgM played a major role in bacterial clearance, a mechanism that still requires translation to pigs.
A multiserotype autogenous vaccine in gilts improved maternal antibody transfer to about five weeks of age but did not reduce shedding or demonstrate clinical protection.
The German ASP-Risikoampel allowed thousands of holdings to self-assess ASF biosecurity, but voluntary results should not be treated as representative of all farms.
Across 18 Hong Kong pig farms, biosecurity scores were modest and several major swine viruses were detected, but the cross-sectional design does not establish causality.
A review of 18 North American studies found that biosecurity adoption is influenced by risk perception, farm size, costs, and behavioral factors.
