Less aggressive pigs may be more susceptible to the emotional impact of victory and defeat but overall, more aggressive pigs express more negative emotionality at the start of agonistic encounters.

Increasing litter size after cross-fostering relative to the number of functional teats of the sow increased piglet preweaning mortality, and tended to decrease weaning weight.

The effects of different boars from the Duroc and Pietrain breeds on the prevalence of swine inflammation and necrosis syndrome in their offspring.

The aim of this study was to determine if enrichment ropes would entice neonatal piglets away from the sow and reduce preweaning mortality.

A high enrichment allowance reduced water usage and wastage.

Early socialised piglets may have better social skills when meeting familiar and unfamiliar conspecifics after weaning.

At lower risk levels, the provision of point-source objects and other less costly but relatively effective measures can play an important role.

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

Pig behavior continues to change for up to 9 wk after introduction into a new social group.

The presence of Salmonella in free-range pigs is directly related to the natural vegetation accessible, determining the composition of the intestinal microbiota.

A short-term music stimulus can reduce the stress response, whereas a long-term music stimulus can enhance immune responses in pigs.

Concentrate feeding level of gestating sows on pasture can be reduced without adverse effects on pasture vegetation cover.

Despite dexterity and visual constraints, pigs have the capacity to acquire a joystick-operated video-game task.

Injection of pGLP-2 microspheres can be a therapeutic strategy for compensatory growth in intrauterine growth restricted piglets with low birthweights.

Swine inflammation and necrosis syndrome is influenced by husbandry and quality of sow in suckling piglets, weaners, and fattening pigs.

After playing with toys, pigs seemed to be less fearful and in a more positive emotional state.

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

Increasing the weaning age can be an effective strategy to improve the overall performance in a commercial system. Results of this study imply that 25 d is the optimal weaning age.

Piglet performances were not improved nor impaired when split-suckling was applied during the first day of life. However growth was impaired when litters were intensively split-suckled during first three days of life.

Following tailor-made implementation of alternative measures, a substantial reduction of antimicrobial use in pig production was achievable without jeopardizing animal health.

Procaine, lidocaine, bupivacaine, and mepivacaine are highly effective at reducing signs of nociception during castration under light isoflurane anesthesia.

Structure, size and flavour should be considered when choosing enrichment material. Out of the materials tested, maize kernels in straw were the most attractive for pigs.

Adding ramps to nursery pig housing is a simple way to speed loading of market hogs, while providing benefits to efficiency and behavior in the nursery.

Pigs exposed to carbon dioxide made more escape attempts but fewer squeals than pigs exposed to nitrous oxide.
