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.
Exploring the effect of play on heart rate variability as a measure of positive emotional states in pigs
Engaging in play increases heart rate variability, with this effect persisting into the period immediately after play.
Environmental enrichment affects immunity and reduces disease severity in pigs after co-infection, with stronger effects when applied from birth than from weaning
Enriched housing from birth reduced disease severity to co-infection with PRRSV and A. pleuropneumoniae.
The promotion of play behaviour in grow-finish pigs: The relationship between behaviours indicating positive experience and physiological measures
Play was successfully promoted and sustained until the finishing period and equally expressed regardless of extra space.
Osteomyelitis in pig carcasses at a Portuguese slaughterhouse: association with tail-biting and teeth resection
Meat inspection data were collected from 100,489 finishing pigs slaughtered in a northern Portuguese abattoir.

The Practical Abstracts on Swine Husbandry ..Effects of space allowance, roughage supplement, and enrichment provision on growth, carcass weight and meat quality in conventional pig husbandry
CONVERSION FROM WARNER-BRATZLER SHEAR FORCE (WBSF) TO SLICE SHEAR FORCE (SSF) TO CLASSIFY PORK LOIN TENDERNESS
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.
Less experienced observers assess piglet castration-induced acute pain differently than experienced observers: A pilot study
The present pilot study supports the enhancement and implementation of UPAPS on farm and laboratory settings by minimally qualified observers.
Breeding for resilience in finishing pigs can decrease tail biting, lameness and mortality
Breeding for resilience traits based on deviations in longitudinal weight data can decrease pigs’ tail biting wounds, lameness and mortality while improving uniformity at the pen level.
Influences on the decision to euthanize a compromised pig
The two most salient reasons outlined for the delay of timely euthanasia were uncertainty and misinterpretation of the chance for healing.
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.
Comparison between intramuscular and intranasal administration of sedative drugs used for piglet castration
Intranasal application showed longer induction times, shorter recovery times and higher scores for defence and vocalisation.
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.
Blood transcriptomic differences in the immune response under stressful environmental according to stocking density
The study confirmed the biological mechanisms through immunological expression patterns according to stocking density.
Split weaning improves pregnancy rate and embryo survival in sows mated in lactation
Weaning a portion of the litter prior to mating in lactation improved pregnancy rates and embryo survival.
Effect of sex and birth weight on the performance, microbiome, immune response and colostrum intake of piglets
Females had a higher rate of permanence in the production system and low birth weight piglets had lower colostrum intake.
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.
Can environmental nebulization of lavender essential oil improve welfare and modulate nasal microbiota of growing pigs?
The study suggests lavender essential oil may improve the welfare of growing pigs. Inhalation of lavendar reduced the nasal microbiome diversity.
Hourly feeding of lactating sows: Enhancing performance and welfare in smart farm-based systems
An hourly feeding regime could optimize sow productive performance, body condition, milk yield, welfare, and piglet growth in swine production.
Effects of space allowance during gestation and socialization training during growing period on the productivity and welfare of primiparous sows
Primiparous sow aggression may be reduced by increasing space allowance during gestation with social training during the growing period.
A second iron injection administered to piglets during lactation improves hemoglobin concentration, growth performance, and carcass characteristics at slaughter
Administering a second iron injection resulted in greater hemoglobin at weaning and the end of the nursery as well as improved growth performance from weaning to the end of study weight and increased carcass weight at slaughter.
Factors associated with farrowing assistance in hyperprolific sows
The frequency of farrowing assistance in sows varied among herds and was influenced by parity number.
Genetic and phenotypic time trends of litter size, piglet mortality, and birth weight in pigs
The increases in litter size and piglet survival rates due to balanced breeding policies lead to reduced total numbers of dead piglets coinciding with a certain pig production volume.
Effect of postpartum meloxicam administration to sows and split-suckling
Postpartum administration of meloxicam to sows reduced clinical cases of disease, increased ADG in pigs, and increased carcass weight at slaughter.
