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.

ASF virus became widely distributed throughout the facility with only minor changes in detection frequency as subsequent batches of feed were produced.

Multiple drinkers provided more frequent and longer water access along with decreased aggression near the water source.

After a 7-wk composting period, Salmonella spp. and vaccine strains of Bovine herpesvirus-1 and Bovine viral diarrhea virus were inactivated using the composting system.

Visit duration of an animal at the single-space feeder was influenced by both direct and social effects when the replacement time between visits was less than 1 minute.

The developed algorithm based on video data has potential to be used for contactless heart rate measurement.

Certain pen modifications resulted in fewer tail damaged pigs and a better overall welfare assessment, despite a tendency for more tail-directed behaviour.

A motion monitoring system based on artificial vision may be used indoors to trigger suspicions of fever.

The air heat pump system has great potential to reduce energy consumption and greenhouse gas emissions.

Two-level systems may reduce aggressive behaviour and social stress in pigs.

Method capable of monitoring feeding behaviour of pigs, without the need for additional sensors or individual marking.
