  3. Good keeper-elephant relationships in North American zoos are mutually beneficial to welfare

    Contributor(s):: Carlstead, Kathy, Paris, Stephen, Brown, Janine L.

    Relationships between animals and their human caretakers can have profound impacts on animal welfare in farms, laboratories and zoos, while human attitudes are important predictors of caretaker behavior towards livestock. In this study, we examined the impact of keeper attitudes about working...

  4. Early socialisation as a strategy to increase piglets’ social skills in intensive farming conditions

    Contributor(s):: Salazar, Laura C., Ko, Heng-Lun, Yang, Chung-Hsuan, Llonch, Lourdes, Manteca, Xavier, Camerlink, Irene, Llonch, Pol

    Socialisation is a process in which animals interact with unfamiliar conspecifics, that allows them to develop their social abilities. Socialisation has been proposed as a method in pig husbandry to increase piglets’ social skills and reduce conspecific aggression, which is a major welfare issue...

  5. Pre-weaning environmental enrichment increases piglets’ object play behaviour on a large scale commercial pig farm

    Contributor(s):: Yang, Chung-Hsuan, Ko, Heng-Lun, Salazar, Laura C., Llonch, Lourdes, Manteca, Xavier, Camerlink, Irene, Llonch, Pol

    Environmental enrichment is a legal requirement for European pig farms. The suitability of enrichment materials for neonatal pigs is understudied and has not been tested in commercial settings. This study investigates the effect of hanging objects and substrate as two enrichment strategies...

  6. Indicators of stress in equitation

    Contributor(s):: König v. Borstel, U., Visser, E. K., Hall, C.

    Stress is a generic concept describing the body’s reaction to external stimuli, including both physiological and psychological factors. Therefore, by definition, the assessment of psychological stress in the exercising horse encompasses the problem of teasing apart the psychological and...

  7. Preliminary evaluation on the effectiveness of varying doses of supplemental tryptophan as a calmative in horses

    Contributor(s):: Davis, Brittany P., Engle, Terry E., Ransom, Jason I., Grandin, Temple

    Tryptophan (Trp), the amino acid precursor to serotonin, is a common ingredient in many commercial equine calming supplements. However, there is little scientific research to support the efficacy of tryptophan at modifying horse behavior. The objective of this study was to examine how various...

  8. Housing conditions do not alter cognitive bias but affect serum cortisol, qualitative behaviour assessment and wounds on the carcass in pigs

    Contributor(s):: Carreras, Ricard, Mainau, Eva, Arroyo, Laura, Moles, Xènia, González, Joel, Bassols, Anna, Dalmau, Antoni, Faucitano, Luigi, Manteca, Xavier, Velarde, Antonio

    Measures of animal emotions are essential to assess animal welfare. Recently, the cognitive bias technique has been proposed as a measure of animal affective state. This technique is based on the premise that subjects in negative affective states make more negative judgements about ambiguous...

  9. The effect of a pressure vest on the behaviour, salivary cortisol and urine oxytocin of noise phobic dogs in a controlled test

    Contributor(s):: Pekkin, Anne-Maria, Hänninen, Laura, Tiira, Katriina, Koskela, Aija, Pöytäkangas, Merja, Lohi, Hannes, Valros, Anna

    Fear of loud noises is a common welfare problem in pet dogs. Commercial treatment vests have been tested on dogs to relieve noise phobia, and peripheral oxytocin has been suggested to be one of the stress-relieving mediators. The effect of vests has not, however, been tested in a controlled...

  10. Relationships between temperament, feeding behaviour, social interactions, and stress in lambs adapting to a feedlot environment

    Contributor(s):: Rice, Maxine, Jongman, Ellen Caroline, Butler, Kym Lloyd, Hemsworth, Paul Hamilton

    The production of lamb meat is a large and important industry in Australia. Variability and seasonality of the climate and the demand for a consistent product (in terms of weight and age) have led to an increase in the use of feedlot systems for finishing lambs. While most lambs acclimatise to...

  11. Physiological stress coping and anxiety in greyhounds displaying inter-dog aggression

    Contributor(s):: Wormald, Dennis, Lawrence, Andrew J., Carter, Gabrielle, Fisher, Andrew D.

    Aggression is a relatively common behavioural problem in dogs that has both animal welfare and human safety considerations. Understanding the behavioural and physiological processes contributing to aggression is required for a better understanding of this issue. Previous studies have examined...

  12. Characterisation of Shy-feeding and Feeding lambs in the first week in a feedlot

    Contributor(s):: Rice, Maxine, Jongman, Ellen Caroline, Borg, Samantha, Butler, Kym Lloyd, Hemsworth, Paul Hamilton

    Up to 20% of lambs introduced to feedlots are prone to ‘Shy-feeding’ or inappetence. Factors considered to contribute to the condition of Shy-feeding include: neophobia (environment and concentrated feeds), disease and competition around feeding. However, little is known about the individual...

  13. Optimizing rearing and welfare in Senegalese sole (Solea senegalesensis) broodstock: Effect of ambient light intensity and handling time on stress response

    Contributor(s):: Figueiredo, Filipe, Aragão, Cláudia, Pinto, Wilson, Dinis, Maria Teresa, Oliveira, Catarina C. V.

    Broodstock rearing conditions and handling procedures should be optimized in aquaculture species in order to benefit fish welfare and guarantee optimal conditions for spawning. In teleosts, basal cortisol levels display daily rhythms, oscillating along the 24 h of the day. In this sense, handling...

  14. Physiological and behavioural evaluation of common anaesthesia practices in the rainbow trout

    Contributor(s):: Pounder, Kieran C., Mitchell, Jennifer L., Thomson, Jack S., Pottinger, Tom G., Sneddon, Lynne U.

    Anaesthetic drugs are commonly administered to fish in aquaculture, research and veterinary contexts. Anaesthesia causes temporary absence of consciousness and may reduce the stress and/or pain associated with handling and certain invasive procedures. The rainbow trout (Oncorhynchus mykiss) is a...

  15. Behavioural and physiological responses of therapy horses to mentally traumatized humans

    Contributor(s):: Merkies, Katrina, McKechnie, Marnie J., Zakrajsek, Emily

    The benefits to humans of equine-assisted therapy (EAT) have been well-researched, however few studies have analyzed the effects on the horse. Understanding how differing mental states of humans affect the behaviour and response of the horse can assist in providing optimal outcomes for both horse...

  16. Behavioral and cortisol responses of adult marmoset monkeys (Callithrix penicillata) to different home-cage social disruption intervals

    Contributor(s):: Duarte, Renata B., Maior, Rafael S., Barros, Marilia

    Social separation is an increasingly used strategy to experimentally assess psychogenic stress in nonhuman primates, yet it is also inherently required for captive management. Surprisingly, little is known on the effects of an individual left alone in a highly familiar place, compared to...

  17. Growing without a mother during rearing affects the response to stressors in rams

    Contributor(s):: Damián, Juan Pablo, Hötzel, Maria José, Banchero, Georgget, Ungerfeld, Rodolfo

    Early maternal care contributes to the normal development of the physiological, social and emotional functions of the offspring. As sheep are a strongly gregarious species, separation and isolation of an individual from the flock provokes fear and, consequently a stress response. The first aim of...

  18. The effects of green odour on domestic dogs: A pilot study

    Contributor(s):: Carlone, Beatrice, Gazzano, Angelo, Gutiérrez, Jara, Sighieri, Claudio, Mariti, Chiara

    Green odour (a mixture of cis-3-hexenol and trans-2-hexenal), similar to cut grass, has been demonstrated to appease subjects of various species (rats, cattle, humans etc.) subjected to different stressful stimuli. The aim of this study was to investigate whether green odour has a calming effect...
