Trait Selection And Welfare Of Genetically Engineered Animals In Agriculture, Michael Greger

Genetics Collection

The release of the Final Guidance from the US Food and Drug Administration on the commercialization of genetically engineered animals has sparked renewed discussion over the ethical, consumer, and regulatory implications of transgenesis in animal agriculture. Animal welfare critiques have focused on unexpected phenotypic effects in animals used in transgenic research, rather than on the health and welfare implications of the intended productivity enhancement. Unless breeding goals are redefined to reflect social concerns, the occurrence and magnitude of undesirable side effects may increase and consumer confidence in the nascent technology may be undermined.

Experimentation Collection

With the release of the landmark report Toxicity Testing in the 21st Century: A Vision and a Strategy, the U.S. National Academy of Sciences, in 2007, precipitated a major change in the way toxicity testing is conducted. It envisions increased efficiency in toxicity testing and decreased animal usage by transitioning from current expensive and lengthy in vivo testing with qualitative endpoints to in vitro toxicity pathway assays on human cells or cell lines using robotic high-throughput screening with mechanistic quantitative parameters. Risk assessment in the exposed human population would focus on avoiding significant perturbations in these toxicity pathways. Computational systems …

Hair Whorls In The Dog (Canisfamiliaris). I. Distribution, Lisa M. Tomkins, Paul Mcgreevy

Anatomy Collection

Hair whorl characteristics were assessed in the domestic dog (Canis familiaris) in the regions of cephalic, cervical (dorsal, ventral, and lateral), thoracic and brachial axillary regions, the chest, shoulders, elbows, ventral abdominal region, and on the caudal thighs (ischiatic). They were classified as simple or tufted, and their position was recorded as the distance between their centers and bony landmarks within each region. The distribution of whorls was explored in a cohort of domestic dogs (N = 120) comprising a variety of breeds and cross‐breeds, sourced from shelters (N = 60) and the general public (N = 60). …

Understanding Mortality Rates Of Laying Hens In Cage-Free Egg Production Systems, The Humane Society Of The United States

Agribusiness Collection

In cage-free egg production systems, concerns have been raised over hen mortality rates. High mortality is an obvious indicator of poor welfare, and problems should be addressed without delay. It is important to note, however, that mortality can vary substantially between hen flocks, and that some cage-free systems have healthy flocks that do not suffer substantial death losses. These systems can serve as models for the rest of the industry, since mortality is not inherent to any particular system, but a consequence of how well the system is managed.

About Fish, Humane Society Institute For Science And Policy

Aquaculture Collection

Although a number of fish species have been studied in their freshwater life stages, further research on the behavior and habitat requirements of ocean-going fish is required. While fishes have historically been regarded as more “primitive” than other vertebrate groups, Rodriguez et al concluded that several memory and learning systems of bony fishes are noticeably similar to those of reptiles, birds, and mammals. When animals as small and under appreciated as fish display complex mating systems, parental care, and demonstrate the ability to traverse significant distances using olfactory and celestial cues, it is clear that previously established definitions of intelligence …

About Turkeys, The Humane Society Of The United States

Agribusiness Collection

John James Audubon, a well-known bird expert and nature enthusiast, described wild turkeys as birds of great beauty. The history and origin of wild turkeys is uncertain, yet many share Audubon’s sentiment that the wild turkey is “one of the most interesting of the birds indigenous to the United States of America.” Today, wild turkeys can be found throughout the nation. Following the selection of the bald eagle as the American symbol, Benjamin Franklin remarked that the turkey was more “respectable”, and a “true original native”.

Hsi Fact Sheet: The Impact Of Animal Agriculture On The Environment And Climate Change In Brazil, Humane Society International

HSI FACT SHEETS

The intensification of farm animal production in industrialized agricultural systems, or factory farms, compromises animal welfare and degrades the environment. Animal agriculture inefficiently consumes natural resources, contributes to deforestation, and produces immense quantities of animal waste, threatening water and air quality and contributing to climate change. The Food and Agriculture Organization (FAO) of the United Nations estimated in 2006 that animal agriculture was responsible for 18% of global, anthropogenic, or human-induced, greenhouse gas emissions and was ―by far the single largest anthropogenic user of land.

About Chickens, The Humane Society Of The United States

Agribusiness Collection

The chicken is the world’s most numerous domesticated bird, with over 52 billion farmed worldwide in 2008, rivaling the dog as the most ubiquitous domestic animal globally. These birds have fascinated scholars and researchers since the dawn of Western civilization, and recent studies are beginning to reveal the depths of their complexity and cognitive ability. According to Andrew F. Fraser, professor of veterinary surgery at Memorial University of Newfoundland, and Donald M. Broom, professor of animal welfare at University of Cambridge: “Those who have studied the behaviour of the domestic fowl in detail…, especially those who have looked at feral …

An Hsi Report: Adopting A Cage-Free Production Policy For Animal Products In Brazil, Humane Society International

HSI REPORTS

Farm animal welfare is becoming an important concern for governments, producers, and consumers worldwide. In particular, intensive confinement systems, such as battery cages and gestation crates, have been acknowledged as severely impairing to the physical comfort and expression of natural behaviors of animals. The European Union and select states in the United States have already passed bills eliminating these housing systems over the next several years. Numerous international retail and food production companies, including Burger King (North America), Smithfield Foods, and McDonald’s (Europe) are committed to gradually eliminating the use and sale of eggs and pork produced via intensive confinement …

An Hsi Report: Food Safety And Cage Egg Production, Humane Society International

HSI REPORTS

Governments have begun legislating against cage egg production and a growing number of major food retailers, restaurant chains, and foodservice providers worldwide are switching to cage-free eggs. Extensive scientific evidence strongly suggests this trend will improve food safety. All fifteen scientific studies published in the last five years comparing Salmonella contamination between caged and cage-free operations found that those confining hens in cages had higher rates of Salmonella, a leading cause of food poisoning worldwide. This has led prominent consumer advocacy organizations, such as the Center for Food Safety, to oppose the use of cages to confine egg-laying hens.

The Public Health Impacts Of Concentrated Animal Feeding Operations On Local Communities, Michael Greger, Gowri Koneswaran

Environment Collection

Large-scale farm animal production facilities, also known as concentrated animal feeding operations (CAFOs), release a significant amount of contaminants into the air and water. Adverse health effects related to exposure to these contaminants among CAFO workers have been welldocumented; however, less is known about their impact on the health of residents in nearby communities. Epidemiological research in this area suggests that neighboring residents are at increased risk of developing neurobehavioral symptoms and respiratory illnesses, including asthma. Additional research is needed to better understand community-scale exposures and health outcomes related to the management practices and emissions of CAFOs.

Laboratory Rodent Welfare: Thinking Outside The Cage, Jonathan P. Balcombe

Laboratory Experiments Collection

This commentary presents the case against housing rats and mice in laboratory cages; the commentary bases its case on their sentience, natural history, and the varied detriments of laboratory conditions. The commentary gives 5 arguments to support this position: (a) rats and mice have a high degree of sentience and can suffer, (b) laboratory environments cause suffering, (c) rats and mice in the wild have discrete behavioral needs, (d) rats and mice bred for many generations in the laboratory retain these needs, and (e) these needs are not met in laboratory cages.

Toward Genuine Rodent Welfare: Response To Reviewer Comments, Jonathan P. Balcombe

Laboratory Experiments Collection

I’m grateful to the editors for soliciting critiques of my commentary and for the opportunity to respond. Because one of the respondents (Patterson-Kane, 2010/this issue) does not take issue with the main points of my article, whereas the other (Blanchard, 2010/this issue) does, I focus my remarks here mostly on Blanchard’s critique.

Problems With Grid Flooring In Dog Kennels, The Humane Society Of The United States

PUPPY MILL REPORTS

Gridded, strand, or wire flooring in dog kennels does not promote either proper sanitation or adequate comfort and safety for dogs and puppies. Grid-style or wire flooring frequently leads to entrapment or injury, as dogs and puppies’ feet become wedged in openings intended for feces. Grid flooring is designed to allow feces to pass through, but unfortunately any gap large enough for fecal matter is large enough to entrap an animal’s foot or toe.

Facts About Cage Stacking, The Humane Society Of The United States

PUPPY MILL REPORTS

One of the most troubling conditions seen at puppy mills is overcrowding, which can lead to sanitation problems, stress, and disease. Puppy mills commonly use stacked cages to house more animals than a given space should reasonably hold.

Missouri’S Dirty Dozen: A Report On Some Of The Worst Puppy Mills In Missouri, The Humane Society Of The United States

PUPPY MILL INFORMATION

The purpose of the report is to demonstrate current problems that could be addressed by the passage of Proposition B, which Missouri citizens will vote on in November. Under Proposition B, the Puppy Mill Cruelty Prevention Act, many of these dealers’ horrific violations would be backed by stronger enforcement opportunities.

All of the puppy mills on the Dirty Dozen list are licensed by the USDA, the state, or both, according to the most recently available records reviewed by HSUS researchers. Some sell puppies to pet stores and others over the Internet. One thing they have in common is atrocious violations …

Noncompliance With Public Health Service (Phs) Policy On Humane Care And Use Of Laboratory Animals: An Exploratory Analysis, Leah M. Gomez, Kathleen Conlee, Martin Stephens

Laboratory Experiments Collection

The National Institutes of Health (NIH) is a major biomedical research-funding body in the United States. Approximately 40% of NIH-funded research involves experimentation on nonhuman animals (Monastersky, 2008). Institutions that conduct animal research with NIH funds must adhere to the Public Health Service (PHS) care and use standards of the Office of Laboratory Animal Welfare (OLAW, 2002a). Institutions deviating significantly from the PHS’s animal care and use standards must report these incidents to the NIH’s OLAW. This study is an exploratory analysis of all the significant deviations reported by animal-research facilities to OLAW during a 3-month period. The study identifies …

A Critical Review Of Electrical Water-Bath Stun Systems For Poultry Slaughter And Recent Developments In Alternative Technologies, Sara J. Shields, A. B. M. Raj

Agribusiness Collection

Prior to slaughter, most farmed birds move through a constant-voltage, multiple- bird, electrical water-bath stun system. Using this system subjects live birds to stressful and painful shackling, and the potential exists for them to receive prestun electric shocks and induction of seizures while still conscious. The existing elec- trical water-bath stunner settings, particularly those used in U.S. slaughter plants, are not necessarily based on sound scientific data that they produce a consistent, immediate stun, and research indicates that they are not effective in all birds. Further, in multiple-bird, electrical water-bath systems, birds may miss the stunner completely. Evidence suggests that …

Do Zoos And Aquariums Promote Attitude Change In Visitors? A Critical Evaluation Of The American Zoo And Aquarium Study, Lori Marino, Scott O. Lilienfeld, Randy Malamud, Nathan Nobis, Ron Broglio

Zoos and Aquariums Collection

Modern-day zoos and aquariums market themselves as places of education and conservation. A recent study conducted by the American Zoo and Aquarium Association (AZA) (Falk et al., 2007) is being widely heralded as the first direct evidence that visits to zoos and aquariums produce long-term positive effects on people’s attitudes toward other animals. In this paper, we address whether this conclusion is warranted by analyzing the study’s methodological soundness. We conclude that Falk et al. (2007) contains at least six major threats to methodological validity that undermine the authors’ conclusions. There remains no compelling evidence for the claim that zoos …

Integrated Pest Management (Ipm) For Vertebrates: Do We Need To Broaden This Concept?, John Hadidian

Ecology Collection

The concepts and practices of Integrated Pest Management (IPM) are historically grounded in programs aimed at insects and disease-causing organisms affecting agriculture. When applied to vertebrates, IPM concepts have most often been used in rodent control programs. Still, IPM is a powerful model that arguably can, and should, apply to conflicts with any “pest” or problem-causing organism. It may be time to examine contemporary IPM approaches and their relation to traditional vertebrate pest control more closely. Vertebrate IPM should encompass not only the development of sound and practical steps to shape decision-making and actions, but a dialogue about ethics as …

The State Of Human-Animal Studies, Kenneth Shapiro, Margo Demello

Attitudes Towards Animals Collection

The growth of human-animal studies (HAS) over the past twenty years can be seen in the explosion of new books, journals, conferences, organizations, college programs, listserves, and courses, both in the United States and throughout Europe, Australia, New Zealand, and Canada. We look as well at trends in the field, including the increasing popularity of animal-assisted therapy programs, the rise of new fields like trans-species psychology and critical animal studies, and the importance of animal welfare science. We also discuss the problems continuing to face the field, including the conservative culture of universities, the interdisciplinary nature of the field, the …

Ignoring Nature: Why We Do It, The Dire Consequences, And The Need For A Paradigm Shift To Save Animals, Habitats, And Ourselves, Marc Bekoff, Sarah Bexell

Ecology Collection

The article discusses the importance of biodiversity and on how people protect animals and habitats. It describes the conservation psychology and conservation social work. It suggests that there will be fewer people who will actually be able to make a positive difference in the relationships with animals and ecosystems.

Becoming Rabbit: Living With And Knowing Rabbits, Margo Demello

Human and Animal Bonding Collection

Rabbits, like all animals (human and non-human), have rich internal lives, as people who live intimately with rabbits can attest.1 Living with house rabbits—where rabbits live indoors, without a cage or with minimal caging, as part of the human family—is, to me, the best way to gain some understanding of the rabbit psyche. In addition,

living closely with rabbits opens up the possibilities of the humanrabbit relationship—a relationship which, until very recently, was one-sided and based on exploitation. Today, however, with the rise of the house rabbit movement, the subjectivity of rabbits has been exposed, leading to the possibility of …

Octopuses (Enteroctopus Dofleini) Recognize Individual Humans, Roland C. Anderson, Jennifer A. Mather, Mathieu Q. Monette, Stephanie R.M. Zimsen

Sentience Collection

This study exposed 8 Enteroctopus dofleini separately to 2 unfamiliar individual humans over a 2-week period under differing circumstances. One person consistently fed the octopuses and the other touched them with a bristly stick. Each human recorded octopus body patterns, behaviors, and respiration rates directly after each treatment. At the end of 2 weeks, a body pattern (a dark Eyebar) and 2 behaviors (reaching arms toward or away from the tester and funnel direction) were significantly different in response to the 2 humans. The respiration rate of the 4 larger octopuses changed significantly in response to the 2 treatments; …

Squid Dances: An Ethogram Of Postures And Actions Of Sepioteuthis Sepioidea Squid With A Muscular Hydrostatic System, Jennifer A. Mather, Ulrike Griebel, Ruth A. Byrne

Sentience Collection

A taxonomy of the movement possibilities for any species, within the constraints of its neural and skeletal systems, should be one of the foundations of the study of its behaviour. Caribbean reef squid, Sepioteuthis sepioidea, appear to have many degrees of freedom in their movement as they live in a three-dimensional habitat and have no fixed skeleton but rather a muscular hydrostatic one. Within this apparent lack of constraints, there are regularities and patterns of common occurrences that allow this article to describe an ethogram of the movements, postures and positions of squid. Squid have a combination of bent, …

Vigilance And Antipredator Responses Of Caribbean Reef Squid, Jennifer A. Mather

Sentience Collection

Antipredator responses, especially those of open-ocean squid, have been seldom studied in the natural environment. Sepioteuthis sepioidea, observed by snorkellers near the shore in early morning/late afternoon, produced an average of eight moves of over 1m per hour, apparently mostly antipredator behaviours. Close approaches by herbivorous parrotfish elicited no response in 74% of encounters; otherwise, squid produced agonistic zebra stripes or startle-mantle-dots skin patterns. Predatory bar jack fish caused flight but not zebra displays, and squid usually paled and fled quickly (66%) from snapper. The speed of approach was the best predictor for flight and display responses to snapper, …

Male Territoriality In A Social Sciurid, Cynomys Gunnisoni: What Do Patterns Of Paternity Tell Us?, J. L. Verdolin, C. N. Slobodchikoff

Veterinary Science and Medicine Collection

In many social sciurids, male territoriality confers significant mating advantages. We evaluated resident male paternity in Gunnison’s prairie dogs (Cynomys gunnisoni), a colonial ground-dwelling sciurid, where males and females cooperatively defend territories. Contrary to findings reported for other social sciurids, our results show that territorial resident males do not gain significant reproductive advantages. Resident males sired the majority of offspring from their respective territories only 10.5% of the time. A single non-resident male sired equal or greater number of offspring than any single resident male 71.2% of the time. While adult males were more likely to sire a greater number …

Behavior Of A Solitary Sociable Female Bottlenose Dolphin (Tursiops Truncatus) Off The Coast Of Kent, Southeast England, Sonja Eisfeld, Mark P. Simmonds, Laura R. Stansfield

Ethology Collection

This article provides a report of the behavior of a solitary sociable dolphin studied on the southeast coast of England in 2007. This is the first study of its kind in which behavior of such a nonhuman animal was systematically studied. By the time of this study, this young female was highly interactive with people in the water. People accompanied the dolphin for 18.4% of the 100 hr of observation, and their presence changed her behavior. The study recorded 39 different behaviors; feeding and resting behaviors declined in frequency in the presence of people. In addition, the dolphin exhibited behavior …
