Intradermal needle-free injection prevents ASF transmission, while intramuscular needle injection does not
This study confirmed the hematogenous transmission of African Swine Fever virus between pigs through needle-sharing.

Infection prediction in swine populations with machine learning
Models provide daily infection probabilities that can be used as a benchmark to more timely support preventive and control strategies on farms.
Reclassification of ASFV into 7 biotypes using unsupervised machine learning
A new classification of ASFV based on comparisons performed considering the entire encoded proteome.
Disasters, population trends, and their impact on the U.S. pork packing sector
Findings suggest physical capacity is not the only factor influencing processing rates and highlight existing vulnerabilities to labor shortages.
Pig manure treatment strategies for mitigating the spread of antibiotic resistance
The composting process can be an efficient strategy for mitigating the spread of antibiotic resistance in the environment.
Effects over time of different types of sounds on gestating sows’ behavior
Frequent emission of short sounds can reduce time spent sleeping and cause behavior changes. However, gestating sows can habituate to the sound stimuli and return to normal behavior.

At #CAHE, we officially ..Welfare and performance of sows and piglets in farrowing pens with temporary crating system
Results suggested that farrowing pens with temporary crating facilitated mother-young interactions and showed a higher crushing rate.
Effects of providing sensory attractants to suckling pigs during lactation and after weaning on post-weaning growth performance
Environmental enrichment with cubes appears to have the greatest effect when applied post-weaning whereas flavor attractants appear to have the greatest effect when applied both pre- and post-weaning.
Effect of slurry funnels with partial pit ventilation on emissions from pig houses
The funnel slurry system can lower emissions of both ammonia, odour and methane.
Survival of a surrogate ASF virus-like algal virus in feed matrices using a 23-day commercial United States truck transport model
Results demonstrate that ASFV-like nucleocytoplasmic large DNA viruses can retain viability in swine feed matrices during long-term transport across the continental United States.
Novel trailer types for transportation of pigs to slaughter
Effects on trailer microclimate, pig behaviour, physiological response, and meat quality under Canadian summer conditions.
Self-administration of a Salmonella vaccine by domestic pigs
This technology could benefit commercial pig production while providing an enriched behavioral environment.

Effects of jute nesting material and enriched piglet mats on sow welfare and piglet survival
The jute material and piglet nests positively impacted sow welfare and piglet measures but did not translate into improved piglet survival.
Effects of pen size, design, bedding, rooting material on cleanliness and air quality in fattening pig houses
Physical and ambient conditions affecting pen and pig cleanliness and air quality.
Automated detection of behavioral changes associated with the post-weaning transition in pigs
The approach is capable of automatically monitoring several different behaviors of a group of pigs at the same time.
Effects of farrowing hut design on maternal and thermoregulatory behavior in outdoor housed sows and piglets
The metal hut appears to be the best compromise considering thermal environment, behavior, and litter survival.
Use of drinkers by finisher pigs depends on drinker location, pig age, time of day, stocking density and tail damage
Results may explain the success of previous studies in classifying tail damage pens from pens without tail damage using sensor data on drinker use.
Analysis of image-based sow activity patterns reveals associations with piglet survival and early growth
The live-born piglets of sows that were more active the day before farrowing, standing and in other activity than drinking and eating, had higher survival rates.

Impacts of evaporative pad cooling on finishing pig performance
Cool cell pads improved pig well-being by providing more cooling than sprinklers but pig performance was unaffected.
The effect of lift crates on piglet survival rate and sow stress level during farrowing
Lift crate sows evidenced an increase in hair cortisol values along with the benefit of the higher survival rate of piglets before weaning.
Machine learning algorithms can predict tail biting outbreaks in pigs using feeding behaviour record
Machine learning models can be considered for implementation into automatic feeder systems for real-time prediction of tail biting events.
