Temperament Behaviours in Individually Tested Sheep Are Not Related to Behaviours Expressed in the Presence of Conspecifics.

Individual behavioural testing in sheep is common; however, outcomes may be misleading as they are a highly gregarious species that is usually managed in groups. We investigated whether behaviour expressed by 3-4-month-old Merino lambs ( = 220) in social isolation was related to their behaviour towards the same stimuli when three other conspecifics were present, and if measures of temperament (vocalisations and locomotory behaviours) were repeatable across both social situations. Expression of all behaviours were reduced when conspecifics were present, and vocalisations were rarely performed in social groups, suggesting that this behaviour is a response to social isolation.

Animal welfare knowledge, attitudes, and practices among livestock holders in Ethiopia.

Improving animal welfare is a human responsibility and influenced by a person's values and experiences. Thus, it is critical to have an in-depth understanding of the knowledge, attitudes, and practices (KAP) of animal welfare among animal owners. For livestock in Ethiopia, the greatest proportion of livestock are reared by pastoral and mixed crop-livestock communities.

Exposure to humans after weaning does not reduce the behavioural reactivity of extensively reared Merino lambs.

Human-directed fear in extensively reared sheep is often high due to the aversive nature of common husbandry procedures and infrequent interactions with humans. This study investigated whether additional human exposure provided to weaned lambs reduced human-directed fear and behavioural reactivity. Ninety Merino lambs were either exposed to low or moderately stressful human exposure sessions, or had no additional human contact, and their fear responses and behavioural reactivity to humans, a startle stimulus and confinement were tested.

Behavioural reactivity testing in sheep indicates the presence of multiple temperament traits.

Temperament in sheep is commonly presented as unidimensional, with a 'nervous' temperament indicative of fear and reactivity towards humans and novel environments. However, temperament is multidimensional, with some traits expressed only under certain conditions (context-specific). There is evidence that a common temperament test in sheep, the isolation-box (IB), measures level of activity and not fearfulness as intended, and that behaviours measured in the IB test are indicative of different traits.

Cognitive Enrichment in Practice: A Survey of Factors Affecting Its Implementation in Zoos Globally.

Information on the practical use of cognitive enrichment in zoos is scarce. This survey aimed to identify where cognitive enrichment is being used while identifying factors that may limit its implementation and success. Distributed in eight languages to increase global range, responses to this survey ( = 177) show that while agreement on what constitutes cognitive enrichment is poor, it is universally perceived as very important for animal welfare.

Positive attitudes, positive outcomes: The relationship between farmer attitudes, management behaviour and sheep welfare.

This study examined the relationships between the attitudes and the management behaviour of the farmer and the on-farm welfare of their ewes. To our knowledge, this is the first study investigating these relationships in extensive sheep farming systems. Thirty-two sheep farmers and 6200 ewes were sampled across Victoria, Australia.

Evaluating the welfare of extensively managed sheep.

The aim of this study was to identify the main on-farm welfare issues likely to be encountered in extensive sheep farming systems. Thirty-two commercial sheep farms in Victoria, Australia were involved in this study. Of the 32 farms involved, 30 were visited twice (at mid-pregnancy and weaning), and 2 farms only once (both at weaning).

Animal-Based Welfare Assessment of Cattle and Water Buffalo in Bangladeshi Slaughterhouses.

This study quantified the welfare of 423 cattle and water buffalo in four Bangladeshi slaughterhouses to identify facility and species-specific factors that influence welfare. The majority of animals arrived at the slaughterhouse with injuries, signs of dehydration and oculo-nasal discharge. During slaughter, buffalo experienced more stabbing at the throat (21%), compared to local cattle (10%, P = 0.

Curious creatures: a multi-taxa investigation of responses to novelty in a zoo environment.

The personality trait of curiosity has been shown to increase welfare in humans. If this positive welfare effect is also true for non-humans, animals with high levels of curiosity may be able to cope better with stressful situations than their conspecifics. Before discoveries can be made regarding the effect of curiosity on an animal's ability to cope in their environment, a way of measuring curiosity across species in different environments must be created to standardise testing.

An assessment of African lion sociality via social network analysis: prerelease monitoring for an reintroduction program.

The wild population of the African lion continues to decline, requiring alternate conservation programs to be considered. One such program is ex situ reintroduction. Prior to release, long-term monitoring and assessment of behavior is required to determine whether prides and coalitions behave naturally and are sufficiently adapted to a wild environment.

Towards a more practical attention bias test to assess affective state in sheep.

Tests for attention bias potentially offer more rapid assessment of affective state in animals than existing cognitive methods. An attention bias test has previously been developed for sheep and validated as a measure of anxious states. The 3 minute test assessed behavioural responses of sheep in an enclosed arena after brief exposure to the threat of a dog.

Stakeholder Perceptions of Welfare Issues and Indicators for Extensively Managed Sheep in Australia.

An online survey was designed to form the basis of a framework for the welfare assessment of extensively managed sheep in Australia. The survey focused on welfare compromise and useful welfare indicators. A total of 952 people completed the survey in its entirety, representing four stakeholder groups: Public (53.

Temperament, age and weather predict social interaction in the sheep flock.

The aim of the current study was to investigate the social relationships between individual sheep, and factors that influence this, through the novel application of the statistical multiple membership multiple classification (MMMC) model. In study one 49 ewes (ranging between 1 and 8 years old) were fitted with data loggers, which recorded when pairs of sheep were within 4m or less of each other, within a social group, for a total of 6days. In study two proximity data were collected from 45 ewes over 17days, as were measures of ewe temperament, weight and weather.

Physiological and Behavioral Responses of Horses to Wither Scratching and Patting the Neck When Under Saddle.

Riding is considered to be an arousing activity for horses. It has been suggested that wither scratching may be a more useful tool for relaxation compared with the common practice of neck patting. In the current study, 18 horses were exposed to 3 treatments, including control or no interaction, neck patting, and wither scratching, for 1 min each following a short obstacle course.

Evaluating pharmacological models of high and low anxiety in sheep.

New tests of animal affect and welfare require validation in subjects experiencing putatively different states. Pharmacological manipulations of affective state are advantageous because they can be administered in a standardised fashion, and the duration of their action can be established and tailored to suit the length of a particular test. To this end, the current study aimed to evaluate a pharmacological model of high and low anxiety in an important agricultural and laboratory species, the sheep.

Physiological and nonphysiological indicators of body condition score in weaner pigs.

The aim of this study was to identify parameters that may be used as objective measures of wellbeing in weaner pigs on farm. Eighty-six weaner pigs were categorized into 3 groups based on their BCS: very compromised (VC, BCS = 1), moderately compromised (MC, BCS = 2), or healthy (HY, BCS ≥ 3). Nonphysiological and physiological measures were then collected from the pigs.

The influence of workplace learning on attitudes toward animal welfare in veterinary students.

Several studies suggest that veterinary students' empathy for animals declines during the years spent at university, yet the factors responsible for this change are not well understood. This study focused on the influence of workplace learning (WPL) on veterinary students' empathy for animals. WPL comprises off-campus placements and is common to all veterinary degree programs.

Measuring judgement bias and emotional reactivity in sheep following long-term exposure to unpredictable and aversive events.

Animal welfare research is now starting to measure the cognitive component of affective states in an effort to improve welfare assessments of animals. Twenty-six Romane ewe lambs were trained to a spatial location task previously demonstrated to test for judgement bias in sheep. This required a go/no-go response according to the location of a bucket in a pen, with one location being positively reinforced (with a feed reward) and the other negatively reinforced (with a fan-forced blower).

Determination of sheep learning responses to a directional audio cue.

There are scientific opinions that a nonhuman animal cannot feel emotions, and, hence, positive experiences, without being cognitive. Therefore, determining an animal's cognitive capacity can be useful in supporting the existence of emotions. Research shows that sheep can perform tasks based on olfactory and visual stimuli; however, little research exists on determining the ability of sheep to perform such tasks based on auditory cues.

Administration of serotonin inhibitor p-Chlorophenylalanine induces pessimistic-like judgement bias in sheep.

Judgement bias has potential as a measure of affective state in animals. The serotonergic system may be one mechanism involved with the formation of negative judgement biases. It was hypothesised that depletion of brain serotonin would induce negative judgement biases in sheep.

The effect of repeated testing on judgement biases in sheep.

Testing judgement biases of animals may provide insight into their affective states; however important questions about methodologies need to be answered. This experiment investigated the effect of repeated testing using unreinforced, ambiguous cues on the response of sheep to a go/no-go judgement bias test. Fifteen sheep were trained to differentiate between two locations, reinforced respectively with feed (positive) or with the presentation of a dog (negative).

The impact of early unilateral brain injury on perceptual organization and visual memory.

Studies of young children with early unilateral brain injury have suggested that while hemispheric differences in visuospatial processing appear to be present early in development, the young brain is better able to compensate for injury than when the injury occurs later, after networks have been established. The aim of this study was to determine if this pattern continues later in development when these children are given a challenging task: the Rey-Osterrieth Complex Figure. Experiment 1 included longitudinal data from ten children with early left hemisphere (LH) injury and nine children with early right hemisphere (RH) injury.
