Veterinarians have obligations towards both the animals they treat and their clients, the owners of the animals. Veterinarians have complicated, and often conflicting, relationships with both groups. In this article, Q-methodology was used as a method for discourse analysis to determine how Dutch large animal practitioners conceptualize animals and their owners and their professional responsibilities towards both. The article focuses on four different perspectives that Dutch veterinarians have of their animal patients and their owners, and of their professional duties and responsibilities. 相似文献

Cat owners commonly consider their pets to be members of their families, and many factors contribute to a high level of owner attachment to their cats. Suppression of a cat's emotional needs in favour of the emotional requirements of the owner may produce a less satisfactory relationship for the owner, and usually for the cat as well. Owners' failure to comprehend their cat's true demands of life, and their false expectation of their ability to fulfil human psychological demands lies at the heart of many feline behaviour problems. 相似文献

Students in animal science and veterinary science at the University of Queensland (UQ) have similar introductory courses in animal handling in year 1 of their degree programs. Veterinary students take animal-handling instruction in farm and companion animals, whereas animal science students are instructed in handling farm animals, horses, and rodents. Veterinary students are introduced to rodents, and animal science students to dogs and cats, in subsequent years of the curriculum. Both cohorts receive additional training, with clinical emphasis for veterinary students in years 3, 4, and 5 of their five-year curriculum. The introductory course is well received by students; both student cohorts appreciate the opportunity provided and the effort that goes into the animal-handling classes. Undergraduates realize that acquiring animal-handling skills will increase their proficiency in their subsequent careers; veterinary graduates recognize that their handling prowess will give their clients confidence in their abilities. Most clients cannot judge the competence of a veterinarian's diagnosis or treatment but will judge their ability based on their handling skills. Ongoing practice allows students to become competent in animal handling. 相似文献

与男生相比,女大学生的人际交往有其自身的特点,主要表现在交往动机理想化、交往圈子生活化和交往行为技巧化三个方面。这三个特点决定了女大学生的人际关系状况对其心理上的影响要比男生更为强烈。 相似文献

本文分析比较了165头超排荷斯坦母牛及其184头女儿的超排反应。从所有母女的整体看,在不同超排反应组,有一种趋势,即在不同反应分组中,母亲与女儿之间,似乎存在一种弱相关(r=0.20)。但在母女不同超排反应的组间,并没有这种相关,即在同一超排反应的母亲组,其相应的女儿组并不存在这种趋势。同一头母亲的2头或3头女儿,似乎母亲超排效果差,女儿的超排效果反而好,而母亲超排反应好,女儿的反应却有降低的趋势。由此得出结论,不能将母亲的超排反应结果作为选择其女儿超排反应的依据。 相似文献

The behaviour and personality of 102 pet rabbits and their interactions with their owners were assessed in their home environment. Information was obtained by interviews with the owner and by direct observation, and the owners were asked to describe the personality of their rabbit. A 10-minute assessment of the rabbit's behaviour in its normal environment was then carried out. Owners who were confident in handling their rabbit handled them more frequently and rabbits that were handled more frequently struggled less when they were being handled. Rabbits observed with a companion spent the largest proportion of their time engaged in social behaviour, and rabbits observed out of a hutch spent significantly more time grazing, hopping and playing. Owners used a wide range of adjectives to describe their rabbits' personalities with the most common term being ;friendly'. 相似文献

The 2001 epidemic of foot-and-mouth disease disrupted the teaching of practical farm animal work for much of that year. Many students in their clinical years in the Faculty of Veterinary Science at the University of Liverpool, went to help to control the disease, both in place of some normal term-time activities and as part of their extramural studies out of term time. This paper, which is based on a questionnaire survey of the students, describes their experiences, the types of work they did, the skills they acquired and their views on the effects of the epidemic on their studies. The vast majority of students felt they had benefited from their experiences and had contributed to combating the epidemic. 相似文献
