The Structure Of Equine Personality, Rachel Etta Kristiansen

Dissertations

The current study was designed to investigate the structure of equine personality. Two personality questionnaires were replicated from previous studies and implemented simultaneously to test the theory that different questionnaires may extract different personality structures. Breed and sex differences were also hypothesized to be significantly different for some personality dimensions. A total of 827 horses were rated on a 90-item personality questionnaire. Participants were recruited online via email and completed the survey at their own convenience. An additional 121 respondents rated a horse that had already been rated; these results were used to calculate inter-rater reliability.

After data collection was …

Assortative Mating In Fallow Deer Reduces The Strength Of Sexual Selection, Mary E. Farrell, Elodie Briefer, Alan G. Mcelligott

Veterinary Science and Medicine Collection

Background: Assortative mating can help explain how genetic variation for male quality is maintained even in highly polygynous species. Here, we present a longitudinal study examining how female and male ages, as well as male social dominance, affect assortative mating in fallow deer (Dama dama) over 10 years. Assortative mating could help explain the substantial proportion of females that do not mate with prime-aged, high ranking males, despite very high mating skew. We investigated the temporal pattern of female and male matings, and the relationship between female age and the age and dominance of their mates.

Results: The peak of …

Molecular Correlates Of Social Dominance: A Novel Role For Ependymin In Aggression, Lynne U. Sneddon, Rupert Schmidt, Yongxiang Fang, Andrew R. Cossins

Ethology Collection

Theoretical and empirical studies have sought to explain the formation and maintenance of social relationships within groups. The resulting dominance hierarchies have significant fitness and survival consequences dependent upon social status. We hypothesised that each position or rank within a group has a distinctive brain gene expression profile that correlates with behavioural phenotype. Furthermore, transitions in rank position should determine which genes shift in expression concurrent with the new dominance status. We used a custom cDNA microarray to profile brain transcript expression in a model species, the rainbow trout, which forms tractable linear hierarchies. Dominant, subdominant and submissive individuals had …

Cognitive Relatives Yet Moral Strangers?, Judith Benz-Scharzberg, Andrew Knight

Animal Welfare Collection

This article provides an empirically based, interdisciplinary approach to the following two questions: Do animals possess behavioral and cognitive characteristics such as culture, language, and a theory of mind? And if so, what are the implications, when long-standing criteria used to justify differences in moral consideration between humans and animals are no longer considered indisputable? One basic implication is that the psychological needs of captive animals should be adequately catered for. However, for species such as great apes and dolphins with whom we share major characteristics of personhood, welfare considerations alone may not suffice, and consideration of basic rights may …

Companion Animals as Laboratory Research Subjects Collection

Dogs are sometimes referred to as “man’s best friend” and with the increase in urbanization and lifestyle changes, dogs are seen by their owners as family members. Society expresses specific concerns about the experimental use of dogs, as they are sometimes perceived to have a special status for humans. This may appear somewhat conflicting with the idea that the intrinsic value of all animals is the same, and that also several other animal species are used in biomedical research and toxicology. This aspect and many others are discussed in an introductory chapter dealing with ethical considerations on the use of …

The workshop participants -- experts from academia, regulatory authorities, a scientific animal welfare organization, and the fish vaccine …

Integrating Values And Ethics Into Wildlife Policy And Management—Lessons From North America, Camilla H. Fox, Marc Bekoff

Conservation Collection

Few animals provoke as wide a range of emotions as wolves. Some see wolves as icons of a lost wilderness; others see them as intruders. As the battle continues between wolf proponents and opponents, finding solutions that resolve conflicts while supporting the integrity of nature is challenging. In this essay we argue that we need to make room for wolves and other native carnivores who are re-colonizing areas from which they were extirpated. Strategies that foster coexistence are necessary and wildlife agencies must consider all stakeholders and invest adequate resources to inform the public about how to mitigate conflicts between …

Effect Of The Prolactin-Release Inhibitor Quinagolide On Lactating Dairy Cows, P. Lacasse, V. Lollivier, R. Bruckmaier, Y. R. Boisclair, G. F. Wagner, M. Boutinaud

Farm Animal Husbandry Collection

In most mammals, prolactin (PRL) is essential for maintaining lactation, and yet the short-term suppression of PRL during established lactation by bromocriptine has produced inconsistent effects on milk yield in cows and goats. To assess the effect of the long-term inhibition of PRL release in lactating dairy cows, 5 Holstein cows in early lactation received daily intramuscular injections of 1 mg of the PRL-release inhibitor quinagolide for 9 wk. Four control cows received the vehicle (water) only. During the last week of the treatments, one udder half was milked once a day (1×) and the other twice a day …

Animal Rights As A Mainstream Phenomenon, Bernard E. Rollin

Animal Rights Movement Collection

Businesses and professions must stay in accord with social ethics, or risk losing their autonomy. A major social ethical issue that has emerged in the past four decades is the treatment of animals in various areas of human use. Society’s moral concern has outgrown the traditional ethic of animal cruelty that began in biblical times and is encoded in the laws of all civilized societies. There are five major reasons for this new social concern, most importantly, the replacement of husbandry-based agriculture with industrial agriculture. This loss of husbandry to industry has threatened the traditional fair contract between humans and …

Animal Welfare In Multipurpose Cattle Production Systems And Its Implications On Beef Quality, Saymore P. Ndou, Voster Muchenje, Michael Chimonyo

Farm Animal Welfare Collection

Animal welfare and its influence on beef production are major considerations in many developed countries. In the developing world, where food insecurity and poverty are prevalent, the welfare of animals receives low priority due to factors such as traditional customs and beliefs, lack of knowledge in animal handling and sub standard handling facilities. This is worsened by the fact that cattle are used for several purposes, such as meat production, milk production, draught power and traditional ceremonies. Research on animal welfare and how it relates to animal production have been done in the developed world. The objective of this study …

An Investigation Of Racing Performance And Whip Use By Jockeys In Thoroughbred Races, David Evans, Paul Mcgreevy

Competitive Animal Racing Collection

Concerns have been expressed concerning animal-welfare issues associated with whip use during Thoroughbred races. However, there have been no studies of relationships between performance and use of whips in Thoroughbred racing. Our aim was to describe whip use and the horses' performance during races, and to investigate associations between whip use and racing performance. Under the Australian Racing Board (ARB) rules, only horses that are in contention can be whipped, so we expected that whippings would be associated with superior performance, and those superior performances would be explained by an effect of whipping on horse velocities in the final 400 …

Scientific Opinion Concerning The Welfare Of Animals During Transport, Efsa Panel On Animal Health And Welfare (Ahaw)

Transport of Farm Animals Collection

The Scientific Opinion on the welfare of animals during transport reviewed the most recent scientific information concerning the main farm species. New scientific evidence and consequent conclusions and recommendations were arranged following the structure of Annex I of EC Regulation 1/2005 . On fitness for transport, recommendations for cattle and poultry were focused on repeated humane handling and careful inspection prior to transport. On the means of transport, use of partitions in horse transport, compulsory fasting of pigs with provision of water at stops, and temperature limits for poultry were major recommendations. Maintaining stability of animal groups was recommended as …

Interpersonal Trauma, Posttraumatic Stress And Depression, Brennan J. Young

Electronic Theses and Dissertations

Dating aggression is common among emerging adults, and women who experience aggression from a dating partner are at risk for elevated depression and posttraumatic stress (Dutton et al., 2006). Although some women end their relationships as a result of aggression, other women remain committed to their partner, and aggression tends to escalate over time. The current study explored the role that depression and posttraumatic stress play in ending aggressive dating relationships as well as changes in these symptoms after ending such a relationship. The current study also sought to identify factors predictive of individual differences in emerging adults' commitment to …

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 …
