Only knowledge generated by the human species was considered until multidisciplinary teams demonstrated the interest of studying other self-medication animal models. Etho-Phytology™ A new discovery model Zoopharmacognosy: animal self-medication using plants1. Etho-Phytology™: a new discovery model based on zoopharmacognosy cases. Material & Method Valid conditions for new cases of “Etho-Phytology™”: • Unusual feeding behavior: the plant is not part of the animal’s traditional diet • Occasional uses: new seasonal eating habits generally limited in time and space • Physiological condition: an animal in poor health making an effort to access a plant • Biological properties: effects already documented for a plant Topical uses of plants Plant ingestion From protection… Among Capuchin Monkeys (Cebus capucinus), in order to prevent certain Diversity of plant elements ingested among primates with therapeutic topical diseases, the plants below are chewed, coated with saliva and rolled purposes : using the hands before being applied directly to the fur2 : • Bitter stems • fruits of the genus Citrus Chimpanzees consumption of the very bitter stem of Vernonia • leaves of Piper marginatum and Clematis dioica amygdalina3 coinciding with the rainy season, which can increase • pods of Sloanea terniflora susceptibility to infections. • Barks Albizia grandibracteata bark consumed by chimpanzees suffering … to socialization from digestive disorders4.

Animal Behaviour, Animal Welfare and the Scientific Study of Affect David Fraser University of British Columbia KEYWORDS animal behaviour, animal welfare, affect, emotion, qualitative research ABSTRACT Many questions about animal welfare involve the affective states of animals (pain, fear, distress) and people look to science to clarify these issues as a basis for practices, policies and standards. However, the science of the mid twentieth century tended to be silent on matters of animal affect for both philosophical and methodological reasons. Philosophically, under the influence of Positivism many scientists considered that the affective states of animals fall outside the scope of science. Certain methodological features of the research also favoured explanations that did not involve affect. The features included the tendency to rely on abstract, quantitative measures rather than description, to use controlled experiments more than naturalistic observation, and to focus on measures of central tendency (means, medians) rather than individual differences.

The discussion has incorporated important areas such as brain anatomy and function, physiological Received in revised form and behavioural responses, and the cognitive abilities that fish possess. Little attention has however, been 10 September 2013 directed towards what functional aspects emotions ought to have in fish. If fish have emotions – why? Accepted 11 September 2013 The elucidation of this question and an assessment of the scientific evidences of emotions in fish in an evolutionary and functional framework would represent a valuable contribution in the discussion on Keywords: whether fish are emotional creatures. Here parts of the vast amount of literature from both biology and Emotions Behaviour psychology relating to the scientific field of emotions, animal emotion, and the functional aspects that Cognition emotions fulfil in the lives of humans and animals are reviewed. Subsequently, by viewing fish behaviour, Psychology physiology and cognitive abilities in the light of this functional framework it is possible to infer what Fish functions emotions may serve in fish. This approach may contribute to the vital running discussion on Evolution the subject of emotions in fish. In fact, if it can be substantiated that emotions are likely to serve a function in fish similar to that of other higher vertebrate species, the notion that fish do have emotions will be strengthened.

  • What You Will Learn in This Course
    What you will learn in this course In this course you will learn how to use the various substances such as essential oils, minerals and macerated oils. You will learn how to offer them to the animals and how to read their responses. At a theoretical level you will learn about the world of plants and how they have used essential oils for millennia. Then you will see how animals have evolved to make use of these substances which the plants secrete for their own purposes. You will learn the basic science of essential oils and the compounds they contain. The next major component is pharmacology, learning how the constituents of plants work in the body to achieve the desired effects. Of course our animals are not concerned with pharmacology. They will simply select what they need, but it is helpful for us to understand how these oils interact with the various organs. Finally you will learn a little about the processes of producing the various substances that we normally use. It is important to understand that the list of oils and other substances explored in this course is not exhaustive or exclusive. There are many therapeutic plants on this planet which may vary from one geographical region to another, but this is a starting point. Later, once you have assimilated the nucleus of the work, you may find that you wish to experiment further including other plants in your kit. How the Course Works This is essentially a home study course so you will work through the various modules at your own pace.

One of these thematic routes is the recently developing Herbs and Spices Network, led by Zánka Herb Valley Visitor and Training Centre based on the collection, cultivation and processing of medicinal plants, herbs and spices. The place of herbs and spices in the diet needs to be considered in reviewing health benefits, including definitions of the food category and the way in which benefits might be viewed, and therefore researched. Here we describe the already established system of the Zánka Herb Valley Visitor and Training Centre, the potential of the Balaton Region in the development of herbal medicine illustrated by the scientific presentation of the 30 most collected herbs in the region and examples of other herbal centres, which are intended to become a part of the network.

    Dr. John Miller (University of Sheffield) Animals, Capital, Literature and the Victorians: Writing the Fur Trade The difference between what we think of as ‘animal’ and what we think of as ‘human’ is routinely conceptualised as a fullness on the side of the human against a poverty on the side of the animal. In response, animal studies, in its emergence over the last twenty years or so, has set about dismantling this crude logic and broadening the scope of humanities research to include the nonhuman. Although at this juncture of the twenty first century, animal studies has the status of an emerging field of study, many of its central concerns are significant ingredients of nineteenth-century thought. Evolutionary theory radically destabilised entrenched ideas of human–animal difference; animal advocacy flowered, through the work of the RSPCA, the vegetarian society and the humanitarian League amongst others; the connections of discourses of species to discourses of race, class and gender became increasingly clear, and increasingly subject to debate, as the century progressed. At the same time, the use of animal bodies in a developing commodity culture accelerated to a remarkable degree, marking the Victorian period, in particular, as an era of extraordinary violence. This paper explores one of the most disturbing examples of this objectification of animal life: the global fur trade. I am interested especially in the ways in which literary fiction both bolstered and contested the conceptions of value behind the fur trade’s commodifying processes. How, I ask, do literature and capital entwine in the imagining of animals as resources to be consumed?

  • Ingestion and Nutrient Utilization
    INGESTION AND NUTRIENT UTILIZATION 9·1 VARIATIONS IN NUTRIENT INTAKE There is a continuous flow of nutrients through the metabolic pathways in an animal-range relationship. There is variation in both the ingestion rate and the turnover rate of different forages as the food is processed by the animal. A time lag also occurs in the conversion of forage to metabolically useful energy for activity and tissue synthesis. An analysis of the characteristics associated with ingestion and the subsequent use of food material provides an understanding of the chemical communication between the animal and its range at a fundamental life-support level. SEASONAL VARIATIONS. Wild ruminants exhibit seasonal differences in the rate of ingestion of different forages. The general pattern observed by many investi­ gators shows a marked drop in consumption that begins ~ n the fall and continues through the winter, with a reversal in the trend in the spring and summer. Males show a greater reduction than females. Silver (unpublished data) reports a 60% decline in intake from September through March for penned adult white-tailed deer on a pelleted diet of grains and alfalfa. Fowler, Newsom, and Short (1967) observed a decline in food consumption of white-tailed deer in Louisiana during the winter, accompanied by a 10% weight loss in bucks and a 3% weight loss in does. A decline in both feeding activity and cedar consumption was recorded for penned animals at the Cusino Wildlife Research Station in Upper Michigan during January and February (Ozoga and Verme 1970). 164 9·1 VAR IATIONS IN NUTRIENT INTAKE 165 Nordan, Cowan, and Wood (1968) have studied the intake of black-tailed deer through several annual cycles, and they observed a very obvious decline in feed intake that begins when male deer exhibit rutting behavior.
