  1. Improving the Welfare of a Zoo-Housed Male Drill (Mandrillus leucophaeus poensis) Aggressive Toward Visitors

    Contributor(s): Metailie, Georges

    Improving the welfare of nonhuman animals in captivity and maintaining behavioral competence for future conservation purposes is of the highest priority for zoos. The behavior of an aggressive male drill (Mandrillus leucophaeus poensis) was assessed in Barcelona Zoo. The 2-year study presented in...

  2. Relationship of Behavioral Interactions during an Animal-assisted Intervention in Assisted Living to Health-related Outcomes

    Contributor(s): Metailie, Georges

    In recent research involving assisted-living residents with mild to moderate cognitive impairment, a structured 12-week Pet Assisted Living (PAL) intervention led to improved physical activity (PA) and mood. Receipt of intervention is important to the efficacy of behavioral interventions. We...

  3. What is the relationship between level of infection and ‘sickness behaviour’ in cattle?

    Contributor(s): Metailie, Georges

    We hypothesised that a range of parasite doses that cause subclinical disease would lead to similar behavioural changes in cattle. This was tested by infecting bull calves with one of four different doses of the gastrointestinal parasite Ostertagia ostertagi: 0 (control), 75,000 (L), 150,000 (M)...

  4. Refuge use affects daily activity patterns in female Xenopus laevis

    Contributor(s): Metailie, Georges

    The African clawed frog (Xenopus laevis) is widely used for scientific research, but its ecology and behavior are poorly understood. In two experiments, the 24h activity patterns of female X. laevis were monitored. In the first, activity was determined both in the presence and absence of a...

  5. Locomotor activity of dairy cows in relation to season and lactation

    Contributor(s): Metailie, Georges

    All systems recording activity of cattle measure it independently of environmental and animal factors. Such recordings may hide differences in activity caused by extraneous interferences or may be inaccurately interpreted. The information produced by sensors could be more accurate, if behaviour...

  6. Individual distance during resting and feeding in age homogeneous vs. age heterogeneous groups of goats

    Contributor(s): Metailie, Georges

    The aim of this experiment was to investigate the individual distance during resting and feeding in homogenous and heterogeneous age groups of young and adult goats. Thirty-six young (3 years) were allotted into 6 groups of young goats (YOUNG), 6 groups of adult goats (ADULT) and 6 heterogeneous...

  7. How much is enough? The amount of straw necessary to satisfy pigs’ need to perform exploratory behaviour

    Contributor(s): Metailie, Georges

    Since 10 years, EU-legislation states that ‘pigs must have permanent access to sufficient quantity of material to enable proper investigation and manipulation activities’. While much research has focused on which materials ‘enable proper investigation and manipulation activities’, little has been...

  8. Fear responses to novelty in testing environments are related to day-to-day activity in the home environment in dairy cattle

    Contributor(s): Metailie, Georges

    Behavioural tests for cattle take time to perform and can be stressful for the animals but are currently the only way of assessing behavioural reactions to fear-causing stimuli in a standardised manner. It may be possible to use behavioural data collected remotely in the home pen environment...

  9. Water-site selection and behaviour of red-legged partridge Alectoris rufa evaluated using camera trapping

    Contributor(s): Metailie, Georges

    This paper explores watering patterns of wild red-legged partridges at water troughs (WT) during three consecutive summers on a farm-land area of Spain where drought periods are frequent. Camera trapping was used in order to assess climatic effects on weekly and daily watering patterns,...

  10. Validation of an algorithm for real-time measurement of sheep activity in confinement by recording movement within a commercial weighing crate

    Contributor(s): Metailie, Georges

    This study reports a method of measuring sheep activity in confinement based on recording movement of sheep during weighing. The aim was to show that an algorithm to analyse continuous weight records could be used to measure activity quickly and efficiently using commercial weighing equipment and...

  11. Sex influences rat personality more than geographical origin

    Contributor(s): Metailie, Georges

    The Norway rat is an indispensable model organism. Behavioral studies on rats usually concentrate on a single trait without considering how different behaviors are linked to each other and whether there are differences in this respect between rat strains or sexes. This study aims to describe the...

  12. Effects of enrichment items on activity and social interactions in domestic horses (Equus caballus)

    Contributor(s): Metailie, Georges

    The aim of this study was to investigate the use of items intended to provide enrichment during turnout, both for individual and group kept horses in an attempt to reduce the amount of passive behaviours. The study was divided into two parts, where study 1 involved eight horses rotated through...

  13. Behaviour around the time of calving in dairy cows

    Contributor(s): Metailie, Georges

    The aim of this study was to investigate behavioural changes before and after calving in dairy cows in order to describe behavioural signs of imminent calving and of cows’ recovery after calving. Thirty-two multiparous Danish Holstein Frisian cows with an unassisted calving were studied from 96h...

  14. Assessing inactivity in zoo gorillas using keeper ratings and behavioral data

    Contributor(s): Metailie, Georges

    One way to address the problem of small sample size in zoo research is to conduct a study involving multiple institutions. However, when conducting behavioral research, it can be difficult for one investigator to travel to each institution or for staff at individual institutions to find time to...

  15. Animal-Assisted Therapy in the Residential Treatment of Dual Pathology

    Contributor(s): Metailie, Georges

    Animal-assisted therapy (AAT) is a complementary intervention of therapy that has shown positive results in the treatment of various pathologies. This study assesses the viability of the implementation and the effectiveness of an AAT program in patients diagnosed with substance abuse disorder and...

  16. Animal-assisted therapy for dementia

    Contributor(s): Metailie, Georges

    BACKGROUND: Dementia is a chronic condition which progressively affects memory and other cognitive functions, social behaviour, and ability to carry out daily activities. To date, no treatment is clearly effective in preventing progression of the disease, and most treatments are symptomatic,...

  17. Assistance Dogs for Persons with Hearing Impairment: A Review

    Contributor(s): Metailie, Georges

  18. Behavioural syndromes in stereotypic striped mice

    Contributor(s): Metailie, Georges

    Stereotypical behaviours (SBs) are abnormal, repetitive behaviours often observed in captivity. SBs are linked to impoverished captive conditions, and stereotypic individuals show a particular set of behaviours (e.g. bolder personality, greater activity) indicating proactive coping. Yet, we do...

  19. Relationships between feeding behaviour, activity, dominance and feed efficiency in finishing beef steers

    Contributor(s): Metailie, Georges

    To increase the profitability and sustainability of beef production systems, the use of animals with high feed efficiency is preferred. Efficient animals eat less than their peers for the same or better growth. This efficiency can be measured using feed conversion ratios (FCR) and residual feed...

  20. A comparison of nocturnal primate behavior in exhibits illuminated with red and blue light

    Contributor(s): Metailie, Georges

    Over evolutionary time, light from the sun, moon, and stars has provided organisms with reliable information about the passage of time; but modern artificial lighting has drastically altered these cues. Evidence is accumulating that exposure to light at night—particularly blue wavelengths—from...
