Enriched housing from birth reduced disease severity to co-infection with PRRSV and A. pleuropneumoniae.

ASFV-G-ΔI177L is not genetically stable and, therefore not safe for use in ASF vaccines. ASF vaccine candidates should be tested for safety in pregnant animals.

Phytogenic feed additive supplementation to piglets challenged with F4-fimbriated enterotoxigenic Escherichia coli reduced the prevalence of fecal E. coli excretion and improved jejunal histomorphology.

Piglets genetically less likely to present swine inflammation and necrosis syndrome signs are also more unlikely to suffer combined skin damage after weaning.

Under the current conditions, the model estimated that an inactivation level (log-kill) of 7.0, 7.2, and 7.3 log must be achieved to manufacture a 10-, 15-, and 20-tons batch size, respectively.

Results suggest great potential of tonsil-oral scraping as a novel, practical, and rapid tool for PRRSV RNA detection in sows to assess sow herd status.

Virus-like particles are a potential clinical candidate for porcine deltacoronavirus vaccination.

Pluck-pools can be valuable diagnostic material.

The study confirmed the biological mechanisms through immunological expression patterns according to stocking density.

Time and temperature combinations effectively decrease the concentration of PRRSV and PEDV on different surfaces.

The average aerosol mass concentration in the test area was over 50% lower than in the control area.

The study suggests lavender essential oil may improve the welfare of growing pigs. Inhalation of lavendar reduced the nasal microbiome diversity.

This study brings compelling evidence of the presence of the most common synanthropic flies near domestic pig farms carrying ASFV DNA.

Maternal flavor conditioning may improve the acceptance and efficacy of iron-supplemented creep feed as an alternative to iron injections in piglets.

This study confirmed the hematogenous transmission of African Swine Fever virus between pigs through needle-sharing.

Sampling guidelines proposed in this study can be used for verification of M. hyopneumoniae infection of gilts following exposure to determine Day 0 of herd closure.

Changes in gut microbial composition significantly altered the functional capacity of steroid hormone biosynthesis in the gut microbiome.

Models provide daily infection probabilities that can be used as a benchmark to more timely support preventive and control strategies on farms.

This study provides insights into the frequency of detection, tissue distribution, and genetic characteristics of PCV4 in the US.

A new classification of ASFV based on comparisons performed considering the entire encoded proteome.

Ear-vein blood swabs, nasal swabs, and oral swabs can be used as surveillance samples for detecting PRRSV RNA by RT-qPCR in weaning-age pigs.

The results here will help inform decisions intended to mitigate the impact of ASF in the Philippines and will contribute to the understanding of the epidemiological dynamics.

The composting process can be an efficient strategy for mitigating the spread of antibiotic resistance in the environment.

Data demonstrate for the first time the protective efficacy of spike-based subunit vaccine, which could be a candidate vaccine against PDCoV.
