The metal hut appears to be the best compromise considering thermal environment, behavior, and litter survival.

Results may explain the success of previous studies in classifying tail damage pens from pens without tail damage using sensor data on drinker use.

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.

Cool cell pads improved pig well-being by providing more cooling than sprinklers but pig performance was unaffected.

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 models can be considered for implementation into automatic feeder systems for real-time prediction of tail biting events.

The LiDAR camera has the potential as a non-invasive tool to help identify the sow's estrus.

Infectious ASF virus particles were rapidly destroyed at day 3.

This study observed impacts of both proximity to weaning and transport duration on piglet welfare indicators.

Results suggest that water disappearance from nipple drinkers was greater than for cup drinkers.

Results suggest that orbital tightening and ear position may be reliable facial action units for the piglet grimace scale.

For this trial, dry disinfectant was the most efficacious in reducing the viral RNA on both boots and subsequent surfaces.

Illuminance could be used to divide the pens into functional areas and, thus, help in meeting pigs’ behavioural needs.

These results suggest no benefit in piglet performance from increasing the width of farrowing pens.

Thermography coupled with Artificial Intelligence systems can help identify and orient the diagnosis of symptomatic animals to prompt adequate reaction at the earliest time.

These results suggest electric-heated mats and heat lamps were comparable in maintaining the performance and postural behaviors of piglets.

Mixing and reducing SID Lys:NE ratio had a more marked impact on performance than reducing space allowance.

Viral pathogens of pigs can survive in representative volumes of feed and feed ingredients during long-distance commercial transport across the continental United States.

The proposed equations can be used for modeling ammonia concentrations and to improve animal welfare and productivity.

Results suggest that an automated recognition system can be developed to monitor pig welfare on-farm.

This study investigated the effects of using acidic substrates on the humification and/or P migration as well as on microbial succession during swine manure composting.

Cooled floor pads combined with chilled drinking water did not affect sow behavior, but did alleviate heat stress partially.

The choice of a feature extraction strategy is a trade-off between the amount of chemical information that is preserved, and the computational effort required to generate the data models.

Mixing had a considerable effect on growth performance and there were a high number of body lesions in the lower space allowance.
