Welfare Assessment: Correlations And Integration Between A Qualitative Behavioural Assessment And A Clinical/Health Protocol Applied In Veal Calves Farms, Marta Brscic, Françoise Wemelsfelder, Elena Tessitore, Flaviana Gottardo, Giulio Cozzi, Cornelis G. Van Reenen Jun 2016

Welfare Assessment: Correlations And Integration Between A Qualitative Behavioural Assessment And A Clinical/Health Protocol Applied In Veal Calves Farms, Marta Brscic, Françoise Wemelsfelder, Elena Tessitore, Flaviana Gottardo, Giulio Cozzi, Cornelis G. Van Reenen

Françoise Wemelsfelder, PhD

This study is aimed at finding correlations and possible integration among Qualitative Behavioural assessment (QBA) and a specific protocol of clinical/health evaluation. Both welfare assessment methods were based on direct animal observation and were applied in 24 Italian veal calves farms at 3 weeks (wks) of rearing. Principal component analysis (PCA) summarized 20 QBA descriptors on two main components (PC1 and PC2) with eigenvalues above 4 and explaining 29.6 and 20.3% of the variation respectively. PCA on residuals obtained after correcting for housing condition yielded highly similar results, indicating that the rearing environment of the calves was not an important …


Assessing The ‘Whole Animal’: A Free Choice Profiling Approach, Françoise Wemelsfelder, Tony E.A. Hunter, Michael T. Mendl, Alistair B. Lawrence Jun 2016

Assessing The ‘Whole Animal’: A Free Choice Profiling Approach, Françoise Wemelsfelder, Tony E.A. Hunter, Michael T. Mendl, Alistair B. Lawrence

Françoise Wemelsfelder, PhD

The qualitative assessment of animal behaviour summarizes the different aspects of an animal’s dynamic style of interaction with the environment, using descriptors such as ‘confident’, ‘nervous’, ‘calm’ or ‘excitable’. Scientists frequently use such terms in studies of animal personality and temperament, but, wary of anthropomorphism, are reluctant to do so in studies of animal welfare. We hypothesize that qualitative behaviour assessment, in describing behaviour as an expressive process, may have a stronger observational foundation than is currently recognized, and may be of use as an integrative welfare assessment tool. To test this hypothesis, we investigated the inter- and intraobserver reliability …


Applying Ethological And Health Indicators To Practical Animal Welfare Assessment, F. Wemelsfelder, S. Mullan Jun 2016

Applying Ethological And Health Indicators To Practical Animal Welfare Assessment, F. Wemelsfelder, S. Mullan

Françoise Wemelsfelder, PhD

There is a growing effort worldwide to develop objective indicators for animal welfare assessment, which provide information on an animal’s quality of life, are scientifically trustworthy, and can readily be used in practice by professionals. Animals are sentient beings capable of positive and negative emotion, and so these indicators should be sensitive not only to their physical health, but also to their experience of the conditions in which they live. This paper provides an outline of ethological research aimed at developing practical welfare assessment protocols. The first section focuses on the development and validation of welfare indicators generally, in terms …


Recognition Of Distress In Animals – A Philosophical Prolegomenon, Bernard E. Rollin Jun 2016

Recognition Of Distress In Animals – A Philosophical Prolegomenon, Bernard E. Rollin

Bernard Rollin, PhD

For those who continue to doubt the studiability of distress or suffering or misery in all of its forms in animals, consider the following thought experiment: If the government were to come up with a billion dollars in research funding for animal distress, would that money go a-begging? We can study these states just as we studied pain—excellent work on boredom by Franciose Wemelsfelder in a volume on laboratory animal welfare I co-edited made the methodology for such study quite explicit. (Wemelsfelder, 1990) And when the ideological scales fall from our eyes, we realize that the work of scientists like …


Influence Of Rock-Pool Characteristics On The Distribution And Abundance Of Inter-Tidal Fishes, Gemma E. White, Grant C. Hose, Culum Brown May 2016

Influence Of Rock-Pool Characteristics On The Distribution And Abundance Of Inter-Tidal Fishes, Gemma E. White, Grant C. Hose, Culum Brown

Culum Brown, PhD

Rock pools can be found in inter-tidal marine environments worldwide; however, there have been few studies exploring what drives their, fish species composition, especially in Australia. The rock-pool environment is highly dynamic and offers a unique natural laboratory to study the habitat choices, physiological limitations and adaptations of inter-tidal fish species. In this study rock pools of the Sydney region were sampled to determine how the physical (volume, depth, rock cover and vertical position) and biological (algal cover and predator presence) parameters of pools influence fish distribution and abundance. A total of 27 fish species representing 14 families was observed …


Human–Wildlife Conflict And Coexistence, Philip J. Nyhus Dec 2015

Human–Wildlife Conflict And Coexistence, Philip J. Nyhus

Philip J. Nyhus

Human interactions with wildlife are a defining experience of human existence. These interactions can be positive or negative. People compete with wildlife for food and resources, and have eradicated dangerous species; co-opted and domesticated valuable species; and applied a wide range of social, behavioral, and technical approaches to reduce negative interactions with wildlife. This conflict has led to the extinction and reduction of numerous species and uncountable human deaths and economic losses. Recent advances in our understanding of conflict have led to a growing number of positive conservation and coexistence outcomes. I summarize and synthesize factors that contribute to conflict, …


Responses Of Four Arthropod Prey Species To Mechanosensory, Chemosensory And Visual Cues From An Arachnid Predator: A Comparative Approach, Scott Kight Dec 2015

Responses Of Four Arthropod Prey Species To Mechanosensory, Chemosensory And Visual Cues From An Arachnid Predator: A Comparative Approach, Scott Kight

Scott Kight

Comparisons of multiple invertebrate prey species to direct predator sensory cues are relatively uncommon. We compared prey responses to arachnid predators (Araneae: Lycosidae) of four species: Blattella germanica (Blattodea: Blattellidae), Acheta domesticus (Orthoptera: Gryllinae), Armadillidium vulgare (Oniscidea: Armadillidae), and Porcellio laevis (Oniscidea: Porcellionidae). Prey experienced combinations of direct mechanosensory, chemosensory or visual cues. All species responded to all cues, but response structure differed among species. Mechanosensory and chemosensory predator cues elicited frequent shifts between behaviors, whereas visual stimuli tended to diminish responses. Mechanosensory stimuli produced the most extreme responses, particularly in crickets and cockroaches, but responses to mechanosensory stimuli diminished …
