An Hsi Report: The Economics Of Adopting Alternatives To Gestation Crate Confinement Of Sows, Humane Society International

HSI REPORTS

There are a number of significant animal welfare concerns associated with gestation crates for sows, including tangible physical and psychological consequences. Studies document a decrease in muscle weight, bone density, and bone strength due to movement restriction and lack of exercise. Unable to engage in natural rooting and foraging behavior, crated sows often engage in “stereotypic” bar-biting, an abnormal behavior characterized by repeated mouthing movements on the metal rails of the crate. Crated sows also suffer from health problems associated with confinement including a higher rate of urinary tract infections as compared to uncrated sows. Continuous close confinement is a …

An Hsi Report: The Impact Of Industrial Farm Animal Production On Food Security In The Developing World, Humane Society International

HSI REPORTS

Food security is often incorrectly used as a justification for the inhumane confinement of animals on industrial farm animal production facilities, while in reality, the industrialization of animal agriculture jeopardizes food security by degrading the environment, threatening human health, and diminishing income-earning opportunities in rural areas. Support from governments and international agencies for more humane and sustainable agricultural systems can ensure adequate food consumption and nutrition throughout the developing world.

Hsus Investigates: New York Puppy Stores, The Humane Society Of The United States

PUPPY MILL INFORMATION

In response to concerns about the sources of puppies in New York pet stores, The HSUS’s Investigations unit conducted a hidden-camera investigation of 11 New York pet stores, visited many of their puppy suppliers, and studied interstate puppy shipping documents for more than 100 New York pet stores in all. Our investigation concluded that, regardless of what pet stores’ sales staff tell shoppers about their puppy sources, all of the stores investigated were buying from inhumane mass-breeding facilities known as puppy mills -- including some of the worst known puppy mills in Missouri and other top puppy mill states.

Update Report: Missouri’S Dirty Dozen, The Humane Society Of The United States

PUPPY MILL INFORMATION

Late last year, researchers at The Humane Society of the United States (HSUS) spent weeks poring over state and federal inspection reports, investigators’ photographs, and enforcement records to compile a list of some of the worst puppy mills in Missouri, known as “Missouri’s Dirty Dozen.” The report included direct quotes detailing horrific care violations documented in the facilities’ federal and/or state kennel inspection reports. The violations included thin-coated breeds like Italian greyhounds found shivering in the cold in temperatures as low as 9 degrees, dogs with open, oozing or bleeding sores, underweight dogs with their entire skeletal structures showing, and …

Examining The Regulatory Value Of Multi-Route Mammalian Acute Systemic Toxicity Studies, Troy Seidle, Pilar Prieto, Anna Bulgheroni

Experimentation Collection

Regulatory information requirements for pesticides call for submission of acute systemic toxicity data for up to three different exposure routes (oral, dermal, inhalation) for both active ingredients and formulated products. Similar multi-route testing is required in the European Union and elsewhere for industrial chemicals. To determine the value of acute toxicity testing by more than one route, oral-dermal and oralinhalation concordances among regulatory classifications were examined for large data sets of chemicals and pesticide active ingredients. Across all sectors examined, oral acute toxicity classifications for pure active substances were more severe than those derived from dermal data in more than …

The Plight Of “Big Black Dogs” In American Animal Shelters: Color-Based Canine Discrimination, Amanda Leonard

Attitudes Towards Animals Collection

The paper begins by describing Big Black Dog Syndrome and its effects in shelters across the United States. I then discuss the physical and environmental factors that contribute to BBD Syndrome; Western symbolism associated with the color black, historical examples of black dogs as negative entities in Western culture, and the concept of “unconscious background checking,” which negatively impacts the adoption rates of BBDs. Lastly, I offer some suggestions as to how shelters in the United States can ameliorate the negative effects of BBD Syndrome.

The Harmful, Nontherapeutic Use Of Animals In Research Is Morally Wrong, Nathan Nobis

Experimentation Collection

It is argued that using animals in research is morally wrong when the research is nontherapeutic and harmful to the animals. This article discusses methods of moral reasoning and discusses how arguments on this and other bioethical issues might be defended and critiqued. A basic method of moral argument analysis is presented and used to show that common objections to the view that “animal research is morally wrong” fail: ie, common arguments for the view that “animal research is morally permissible” are demonstrably unsound or in need of defense. It is argued that the best explanations why harmful, nontherapeutic research …

Physiological And Genetic Correlates Of Boldness: Characterising The Mechanisms Of Behavioural Variation In Rainbow Trout, Oncorhynchus Mykiss, Jack S. Thomson, Phillip C. Watts, Tom G. Pottinger, Lynne U. Sneddon

Aquaculture Collection

Bold, risk-taking animals have previously been putatively linked with a proactive stress coping style whereas it is suggested shyer, risk-averse animals exhibit a reactive coping style. The aim of this study was to investigate whether differences in the expression of bold-type behaviour were evident within and between two lines of rainbow trout, Oncorhynchus mykiss, selectively bred for a low (LR) or high (HR) endocrine response to stress, and to link boldness and stress responsiveness with the expression of related candidate genes. Boldness was determined in individual fish over two trials by measuring the latency to approach a novel object. Differences …

Beyond Anthropomorphism: Attributing Psychological Properties To Animals, Kristin Andrews

Attitudes Towards Animals Collection

In the context of animal cognitive research, “anthropomorphism” is defined as the attribution of uniquely human mental characteristics to non-human animals. Those who worry about anthropomorphism in research are confronted with the question of which properties are uniquely human. As animals, humans and non-human animals1 share a number of biological, morphological, relational, and spatial properties. In addition, it is widely accepted and humans and animals share some psychological properties such as the ability to fear or desire. These claims about the properties animals share with humans are often the products of empirical work.

Cetaceans And Primates: Convergence In Intelligence And Self-Awareness, Lori Marino

Sentience Collection

Cetaceans (dolphins, porpoises and whales) have been of greatest interest to the astrobiology community and to those interested in consciousness and selfawareness in animals. This interest has grown primarily from knowledge of the intelligence, language and large complex brains that many cetaceans possess. The study of cetacean and primate brain evolution and cognition can inform us about the contingencies and parameters associated with the evolution of complex intelligence in general, and, the evolution of consciousness. Striking differences in cortical organization in the brains of cetaceans and primates along with shared cognitive capacities such as self-awareness, culture, and symbolic concept comprehension, …

Pantomime In Great Apes: Evidence And Implications, Ann E. Russon, Kristin Andrews

Sentience Collection

We recently demonstrated, by mining observational data, that forest-living orangutans can communicate using gestures that qualify as Pantomime. Pantomimes, like other iconic gestures, physically resemble their referents. More elaborately, pantomimes involve enacting their referents. Holding thumb and finger together at the lips and blowing between them to mean balloon is one example. Here we sketch evidence of pantomime in other great apes, methodological concerns, and sophisticated cognitive capabilities that great ape pantomimes suggest.

Sentience Collection

The social milieus of animals can be complex, ranging from almost completely asocial to monogamous pairs (no mean feat) to entire societies. To adapt to a constantly shifting environment of individuals striving toward their own goals, animals appear to have evolved specialized cognitive abilities. As appealing and intuitive as the idea of social cognition is, just defi ning it is diffi cult. We attempted to delineate social cognition, speculate on its adaptive value, and come to an understanding of what we mean when we talk about complexity. Transitive inference was often brought up as an example of a cognitive ability …

Physiological And Genetic Correlates Of Boldness: Characterising The Mechanisms Of Behavioural Variation In Rainbow Trout, Oncorhynchus Mykiss, Jack S. Thomson, Phillip C. Watts, T. G. Pottinger, Lynne U. Sneddon

Pain Perception In Fish: Evidence And Implications For The Use Of Fish, Lynne U. Sneddon

Veterinary Science and Medicine Collection

Pain assessment in fish is particularly challenging due to their evolutionary distance from humans, their lack of audible vocalization, and apparently expressionless demeanour. However, there are criteria that can be used to gauge whether pain perception occurs using carefully executed scientific approaches. Here, the standards for pain in fish are discussed and can be considered in three ways: neural detection and processing of pain; adverse responses to pain; and consciously experiencing pain. Many procedures that we subject fish to cause tissue damage and may give rise to the sensation of pain. Fish are popular as pets, in animal exhibits, and …

Microclimate Preferences Of The Grey-Headed Flying Fox (Pteropus Poliocephalus) In The Sydney Region, Stephanie T. Snoyman, Culum Brown

Sentience Collection

The population size of the grey-headed flying fox (Pteropus poliocephalus) has decreased dramatically as a result of a variety of threatening processes. This species spends a great proportion of time in roosting large social aggregations in urban areas, causing conflict between wildlife and humans. Little is known about why these bats choose to roost in some locations in preference to others. Roost selection by cave-dwelling bats can be greatly influenced by microclimatic variables; however, far less is known about microclimate selection in tree-roosting species despite the direct management implications. This study aimed to determine the microclimate characteristics of P. poliocephalus …

Qualitative Behavioural Assessment And Quantitative Physiological Measurement Of Cattle Naïve And Habituated To Road Transport, C. A. Stockman, T. Collins, A. L. Barnes, D. Miller, S. L. Wickham, D. T. Beatty, D. Blache, F. Wemelsfelder, P. A. Fleming

Veterinary Science and Medicine Collection

The present study examined whether observers could distinguish between cattle that are naïve to road transport and the same cattle after becoming more habituated to transport. The behavioural expression of cattle was assessed through the method of qualitative behavioural assessment (QBA), and these assessments were correlated with various physiological parameters. Fourteen Angus steers were assessed during their first road trip and then again on their ninth trip, 15 days later. Blood samples were collected immediately before and after transport, and heart rate and core body temperature were measured continuously throughout each trip. Video footage recorded during each trip was edited …

Environmental Challenge And Animal Agency, Marek Špinka, Françoise Wemelsfelder

Sentience Collection

Challenges are there to be overcome – seen usually as problems to avoid rather than as opportunities to enjoy. However, for humans a life without challenge would be likely to be dull and boring, lacking the enthusiasm and satisfaction that come with individual development. Could this also be true for animals? This chapter looks at the positive value of engaging with environmental challenges for animal welfare, proposing that this value lies in an animal’s expression of agency and the enhanced functional competence that it gains through this. It explores the different facets of agency, and provides more detailed discussion of …

A Kenyan Perspective On The Use Of Animals In Science Education And Scientific Research In Africa And Prospects For Improvement, Charles Kimwele, Duncan Matheka, Hope Ferdowsian

Experimentation Collection

Introduction: Animal experimentation is common in Africa, a region that accords little priority on animal protection in comparison to economic and social development. The current study aimed at investigating the prevalence of animal experimentation in Kenya, and to review shortfalls in policy, legislation, implementation and enforcement that result in inadequate animal care in Kenya and other African nations. Methods: Data was collected using questionnaires, administered at 39 highly ranked academic and research institutions aiming to identify those that used animals, their sources of animals, and application of the three Rs. Perceived challenges to the use of non-animal alternatives and common …

Signs Of Mood And Anxiety Disorders In Chimpanzees, Hope Ferdowsian, Debra Durham, Charles Kimwele, Godelieve Kranendonk, Emily Otali, Timothy Akugizibwe, J. B. Mulcahy, Lilly Ajarova, Cassie Meré Johnson

Sentience Collection

Background: In humans, traumatic experiences are sometimes followed by psychiatric disorders. In chimpanzees, studies have demonstrated an association between traumatic events and the emergence of behavioral disturbances resembling posttraumatic stress disorder (PTSD) and depression. We addressed the following central question: Do chimpanzees develop posttraumatic symptoms, in the form of abnormal behaviors, which cluster into syndromes similar to those described in human mood and anxiety disorders?

Methodology/Principal Findings: In phase 1 of this study, we accessed case reports of chimpanzees who had been reportedly subjected to traumatic events, such as maternal separation, social isolation, experimentation, or similar experiences. We applied and …

Self-Harm In Laboratory-Housed Primates: Where Is The Evidence That The Animal Welfare Act Amendment Has Worked?, Jonathan Balcombe, Hope Ferdowsian, Debra Durham

Animal Welfare Collection

The 1985 amendment to the United States Animal Welfare Act (AWA) to promote psychological well being of primates in the laboratory represents an acknowledgment of an important welfare problem concerning nonhuman animals. How effective has this amendment been? Perhaps the best-known contributor to psychological distress in primates in the laboratory is nonsocial housing; yet, available analyses suggest that little progress has been made in avoiding single-caging of these animals. Another way to assess psychological well being is to examine rates of self-abusive behavior in laboratory primates. If the AWA has been effective, then post-AWA self-harm rates might be lower than …

Microdialect And Group Signature In The Song Of The Skylark Alauda Arvensis, Elodie Briefer, Fanny Rybak, Thierry Aubin

Sentience Collection

The Skylark Alauda arvensis is a territorial species of open landscape in which pairs settle in stable and adjacent territories during the breeding season. Due to the heterogeneity of the habitat, territories are gathered in patches spaced by a few kilometres, in which each male produces very long and complex flight songs as a part of the territorial behaviour. We showed that, in a given patch, all the males (neighbours) share some particular sequences of syllables in their songs, whereas males settled in different patches (strangers) have almost no sequences in common. Such a phenomenon is known as microdialect. To …

Resisting The Globalization Of Speciesism: Vegan Abolitionism As A Site For Consumer-Based Social Change, Corey Lee Wrenn

Globalization and Social Movements Collection

Globalization has exacerbated speciesism both socially and economically. Veganism and its subsequent labeling schemes have arisen as an important political site of resistance to growing non-human animal inequality. This paper explores globalization‘s impact on non-human animals, veganism and vegan labeling, as well as important divides within the modern non-human animal rights movement in regards to utopian and pragmatic approaches to alleviating growing speciesism.

Population Survey (Census) Of Stray Dog Population In Ahmedabad, Gujarat, Rahul Sehgal, Sunil Chawla, Jack Reece

Stray and Feral Animal Populations Collection

Ahmadabad, the biggest city of Gujarat with a human population of approximately, 6 million. The rapidly expanding population of Ahmadabad means that the metropolitan region extends far outside from the confines of the old city. However, the development is rapid but uncontrolled. Therefore, there are a large number of areas that are prone to stray dogs and these areas are constantly increasing. The old methods of population control by strychnine poisoning or electrocution employed by the municipal corporations have not proved effective in controlling street dog populations, as new dogs soon migrate into the areas, where the local dog population …

Haemato-Biochemical Changes In Natural Cases Of Canine Babesiosis, Showkat Ahmad Shah, Naresh Kumar Sood, Srinivasa Rao Tumati

Biochemistry Collection

Incidence of severe anemia due to babesiosis in dogs resulting in death in a short time of illness is on the increase in Punjab, during last few decades due to introduction of exotic breeds like Grey Hound, German shepherd, Doberman, Labrador and others. In the present study the hematological and biochemical changes in blood samples obtained from 4 dogs naturally infected with Babesia were evaluated. The dogs were presented to the Department of Veterinary Clinical Services Complex, GADVASU, Ludhiana from August 2008 to April 2009. The evaluation included Hemoglobin (Hb), Red Blood Cell count (RBC), Packed Cell Volume (PCV), Mean …

Biochemical Methane Potential Of Different Organic Wastes And Energy Crops From Estonia, M. Luna-Derisco, A. Normak, K. Orupõld

Biochemistry Collection

The biochemical methane potential (BMP) of different Estonian substrates as alternative sources for biogas production was studied. For this purpose, the BMP test was carried out in batch mode at mesophilic temperature (36°C). Substrates were divided into 2 groups: agricultural substrates (silage, hay, cattle and pig slurry) and food industry residues (milk, brewery and cereal industry residues). Methane yields obtained were between 286–319 L kgVS^-1 for silage and hay, 238–317 L kgVS^-1 for animal slurry and 272–714 L kgVS^-1 for agro-industrial wastes. The highest methane yield was obtained from sour cream (714 L kgVS^-1), the …
