The process of spontaneous learning in an automatic food dispenser by a group of domestic female pigs was studied when one of the animals of the group had an aversive experience. Restraining a gilt in the dispenser without access to food resulted in later avoidance of the system by other gilts, especially when the reactions of the restrained animal had been especially violent and associated with urination. The hypothesis of a delayed transmission of an unpleasant experience was tested. The food… 
Emotions on the loose: emotional contagion and the role of oxytocin in pigs
TLDR
A role for oxytocin in pig communication, which merits further research, is suggested, as behavioral differences found between the positive andnegative treatments show that the treatments induced a positive and negative emotional state in the training pigs, respectively.
Sources of stress in captivity
Young female pigs can discriminate individual differences in odours from conspecific urine
TLDR
Investigation of whether 10-week-old female pigs are able to discriminate between urinary odours from similar-aged conspecifics that were unfamiliar indicates that young pigs could use urinary cues to discriminate other individuals.
Use of a putative maternal pheromone during transport and the effect of trailer temperatures on pig losses and welfare
The efficacy of a maternal pheromone (MP) to reduce transport stress was evaluated in a field study. In addition, we determined the appropriate field sample sizes for measures of death rate and the
Temporary inactivation of the anterior part of the bed nucleus of the stria terminalis blocks alarm pheromone-induced defensive behavior in rats
TLDR
The data indicate that the aBNST plays an important role in the mediation of the alarm pheromone-induced defensive behavior in rats, and that local microinjections of the GABAA receptor-agonist muscimol modulates alarm phersomone -induced defensive behaviors.
Identification of a pheromone that increases anxiety in rats
TLDR
This study discovered that a combination of two molecules, 4-methylpentanal and hexanal, increased anxiety in rats and concluded that the mixture is a pheromone in rats that can increase anxiety in conspecifics.

Discrimination of the Odor of Stressed Rats
TLDR
Albino rats can reliably distinguish between the odors of stressed and unstressed rats, and the discrimination does not seem to depend on recognition of odor of individual rats.
Mechanisms mediating the stimulatory effects of the boar on gilt reproduction.
TLDR
The prepubertal gilt is used as the model for response of female pigs to boar stimuli, as most of the research data is to be found in this area and a tentative mechanism of action of the boar effect is postulated.
The sources of odors from stressed rats
Chemocommunication among prey and predator species
TLDR
Experiments indicated that stressed gerbils produce blood odors that stimulate physiological arousal and cause conspecifics to avoid areas contaminated with these odors, which are ecologically important in the interaction between prey and predator.
