Abstract333 Emerging Voices - Impact of nest covers on welfare and performance of temporarily crated sows and their piglets during lactation
This work supports the use of temporary crating as a viable alternative to conventional farrowing crates. Final thesis at the Department of Animal and Food Science of the Faculty of Veterinary Medicine, UAB, Spain, advised by Pol Llonch Obiols.
Effects of stocking density and illuminance in lairage of fattening pigs in different temperatures
Stocking at too-high density at high temperatures and stocking of too-low density at low temperatures affect meat quality and animal welfare.
Genetic parameters for image-based estimations of swine feet and leg conformation traits
The current study presents an algorithm that extracts novel, objective structural conformation traits and reports corresponding genetic and phenotypic parameters.
Integrating computer vision algorithms and RFID system for identification and tracking of group-housed animals
The proposed framework enabled reliable tracking of group-housed pigs for extended periods, offering a promising alternative to the independent use of image or RFID approaches alone.

Ad libitum feeding systems for lactating sows: effects on productivity and welfare of sows and piglets
Data suggest that sows fed ad libitum eat what they need and can convert feed more efficiently into the piglets’ growth without additional weight loss.
Influence of deep-litter bedding materials on environmental and welfare-related factors in boar studs
Trial runs were conducted in winter and summer to compare five deep-litter bedding materials.
Cooking loss estimation of semispinalis capitis muscle of pork butt using a deep neural network on hyperspectral data
Nondestructive prediction of the quality properties of pork butts can be achieved using hyperspectral images obtained from the semispinalis capitis muscle.
Online feeding behavior monitoring of individual group-housed grow-finish pigs using a low-frequency RFID electronic feeding system
A framework for monitoring feeding behavior of grow-finish pigs in real time, using a low-frequency radio frequency identification system.
Automated oestrous detection in sows using a robotic imaging system
Combining vulva volume features with days from weaning could be a suitable method to detect the onset of oestrous in sows.
Enrichment for growing pigs - Impact on behavior and skin lesions
Findings suggest that the choice of point enrichment object can influence the level of interaction, level of interest over time, activity level, and skin lesions in growing pigs.

Sound feeding signal for gestating sows: Evaluation of an individual learning strategy and its beneficial effects in groups
This study investigates the potential of teaching gestating sows an individual sound signal to reduce aggression resulting from competition for feed access.
Long-term measurement of lying behavior in crates and free-farrowing pens using 3D accelerometers
This study proves the accuracy of accelerometer-based sow lying behavior classification and shows that free-farrowing systems benefit lactating sows.
Added aroma changes pig behaviour in novel situation aimed for stunning
An added aroma increased pigs’ exploration behaviour towards the foam, and thus could serve as a distraction when inside a confined foam box.
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.
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.
