Access to veterinary care: evaluating working definitions, barriers, and implications for animal welfare.

Humans have a moral obligation to meet the physical and mental needs of the animals in their care. This requires access to resources such as veterinary care, which is integral to achieving animal welfare. However, "access" to veterinary care is not always homogenous across communities and currently lacks a consistent definition.

The Behavioural Impact on Cats during a Transition from a Clay-Based Litter to a Plant-Based Litter.

Current guidelines recommend transitioning cats from one litter product to another over 6 days to minimize stress. The study objective was therefore to test these guidelines using 16 adult domestic cats (2 cohorts of 8) by observing behavioural changes associated with elimination throughout the litter transition. Cats were transitioned from a clay-based litter (CLAY) to a plant-based litter product (PLANT) over 6 days (period 1) via an incremental replacement of CLAY with PLANT.

Acquisition of a Joystick-Operated Video Task by Pigs ().

The ability of two Panepinto micro pigs and two Yorkshire pigs () to acquire a joystick-operated video-game task was investigated. Subjects were trained to manipulate a joystick that controlled movement of a cursor displayed on a computer monitor. The pigs were required to move the cursor to make contact with three-, two-, or one-walled targets randomly allocated for position on the monitor, and a reward was provided if the cursor collided with a target.

Changes in Behaviour and Voluntary Physical Activity Exhibited by Sled Dogs throughout Incremental Exercise Conditioning and Intermittent Rest Days.

Participation in repetitive endurance training decreases sled dogs' voluntary activity and locomotive behaviours; however, the changes in their voluntary physical activity over consecutive rest days has not been examined to assess exercise-recovery. The objective of this study was to examine the changes in behaviour and voluntary activity of sled dogs throughout repetitive incremental conditioning and intermittent rest days. Fourteen dogs (6 males, 8 females; age 3.

A critical review of advancement in scientific research on food animal welfare-related air pollution.

Air pollution generates hazardous pollutants that have resulted in safety, health, and other welfare issues of food animals. This paper reviewed scientific research advancement in food animal welfare-related air pollution based on 219 first-hand research publications in refereed journals (referred to as "RPs") over the past nine decades. Scientific studies in this area began in the 1930s.

Investigating the effects of incremental conditioning and supplemental dietary tryptophan on the voluntary activity and behaviour of mid-distance training sled dogs.

Serotonin is a neurotransmitter synthesized by the amino acid tryptophan, that has the potential to impact the behaviour and activity of dogs. The objective of this study was to assess the effects of supplemental tryptophan and a 12-week incremental training regimen on the voluntary activity and behaviour of client-owned Siberian Huskies. Sixteen dogs were blocked for age, BW and sex and then randomly allocated to either the control or treatment group.

Evaluating the validity and reliability of a visual dental scale for detection of periodontal disease (PD) in non-anesthetized dogs (Canis familiaris).

Periodontal disease is one of the most common conditions affecting companion dogs. The objectives of this cross-sectional study were: to determine 1) the agreement between visual assessments (VA) of periodontal disease (PD) performed on awake dogs and the reference standard (RS) of a dental examination and radiographs performed with the dog under general anesthesia, and 2) inter-rater reliability (IRR) for two individuals performing VAs of PD on the same dogs. One hundred and eight dogs were recruited from three veterinary practices.

US Residents' Perceptions of Dog Welfare Needs and Canine Welfare Information Sources.

The extent to which welfare needs of breeding dogs are met in commercial dog-breeding kennels is a potential point of controversy. This analysis sought to understand US residents' perceptions and priorities related to dog welfare : by investigating (a) perceptions of breeding-dog welfare needs and (b) perceptions of various nonhuman animal welfare information sources. Using best/worst-choice experiments conducted in an online survey, respondents' choices for most and least important breeding-dog welfare needs (n = 508) and most/least trusted canine welfare information sources (n = 508) were analyzed.

A cross-sectional study to estimate prevalence of periodontal disease in a population of dogs (Canis familiaris) in commercial breeding facilities in Indiana and Illinois.

The objectives of this cross-sectional study were: 1) to estimate the prevalence and characterize the severity of periodontal disease in a population of dogs housed in commercial breeding facilities; 2) to characterize PD preventive care utilized by facility owners; and 3) to assess inter-rater reliability of a visual scoring assessment tool. Adult dogs (N = 445) representing 42 breeds at 24 CB facilities in Indiana and Illinois were assessed. Periodontal disease was scored visually using the American Veterinary Dental Collage 0-IV scale.

Perceptions of Social Responsibility of Prominent Animal Welfare Groups.

Nonhuman animal welfare is an increasingly important component of consumer expectations of corporate social responsibility (CSR). The extent to which prominent animal welfare or protection organizations may influence people's perceptions of food industry CSR may be related to an organization's perceived social responsibility. Data from an online survey of 300 U.

Stated Preferences for Dog Characteristics and Sources of Acquisition.

People's preferences for where they acquire dogs and the characteristics they focus on may provide insight into their perceptions of socially responsible pet ownership, as acquiring a dog is the first step in dog ownership. An online survey of 1523 U.S.

Behavior and Welfare of Domestic Cats Housed in Cages Larger than U.S. Norm.

The effect of providing additional floor space on cat behavior and welfare is not well documented. This study involved replication of an investigation of cats' responses to enhanced cage and room environments using cages of 0.56 m with the same methodology but an increased space allowance of 1.

Management Practices of Cats Owned by Faculty, Staff, and Students at Two Midwest Veterinary Schools.

Understanding cat owners' housing, care, and management practices is important for promoting cat welfare. A survey study was conducted on the housing and management practices used for cats by students, faculty, and staff of The Ohio State University and Purdue University veterinary colleges. Subjects were 138 cat-owner dyads.

Environmental Aspects of Domestic Cat Care and Management: Implications for Cat Welfare.

Domestic cats () are the most commonly kept companion animals in the US with large populations of owned (86 million), free-roaming (70 million), research (13,000), and shelter (2-3 million) cats. Vast numbers of cats are maintained in homes and other facilities each year and are reliant on humans for all of their care. Understanding cat behavior and providing the highest quality environments possible, including positive human-cat interactions, based on research could help improve the outcomes of biomedical research, shelter adoptions, and veterinary care, as well as overall cat welfare.

Words matter: implications of semantics and imagery in framing animal-welfare issues.

As criticisms of contemporary farm-animal production escalate, scholars have begun to scrutinize the imagery and linguistic techniques used to frame animal issues and their implications. Pro-animal rights groups typically present animal use as unnecessary, oppressive, and exploitive and adopt themes of compassion and protection to engage the public. In contrast, anti-animal rights groups represent animal use as necessary for human benefit and often situate animal and human interests as being incompatible.

A comparison of veterinary students enrolled and not enrolled in an animal-welfare course.

An online survey was conducted to compare 46 veterinary students who previously enrolled in a discussion-based animal-welfare elective with 45 veterinary students who did not take the course. Students were asked a series of questions about their attitudes toward animal welfare and were presented with animal-use scenarios that had not previously been discussed in the elective course: greyhound racing, veal calf production, and the use of genetically engineered mice in research. For each scenario, students' actual knowledge was scored on the basis of open-ended factual questions.

Effects of rubberized flooring on Asian elephant behavior in captivity.

Six Asian elephants at the Oregon Zoo were observed to determine the effects of a poured rubber flooring substrate on captive Asian elephant behavior. Room utilization also was evaluated in seven rooms used for indoor housing, including Front and Back observation areas. Data were collected in three phases.
