Ld50: A Cruel Waste Of Animals

Close Up Reports

Imagine a test in which up to 100 animals are forced to consume a toxic substance in an amount high enough to kill half of them. Then imagine that the explicit purpose of the test is to kill those animals. Incredibly, such a test not only exists but each year also claims the lives of from two to four million animals.

The test is the lethal dose 50, or LD50 as it's commonly called. Its purpose is to measure the toxicity of a substance by determining how much of that substance will kill half of a group of some 60-100 …

International Journal for the Study of Animal Problems

Fox reviews two books. The first is a collection of papers from the First Conference on Scientific Perspectives in Animal Welfare organized by the Scientists Center for Animal Welfare. The second book is All that Dwell Therein. Animal Rights and Environmental Ethics by Tom Regan.

Thoughtful Use Of Animals, Hyram Kitchen

Experimentation Collection

As part of a symposium held in Cincinnati entitled, "Ethical Issues Related to the Use of Research Animals," I was asked by the program director to consider whether further legislation regarding the use of animals might be necessary to ensure more thoughtful use of animals at universities. The following is my response.

Psychology And Its Animal Subjects, Kenneth J. Shapiro

Experimentation Collection

By way of introducing Psychologists for the Ethical Treatment of Animals (PsyETA) to readers of the journal, I have been asked to make some comments about the organization and, from a personal point of view, to suggest some of my own positions and views.

A Survey Of Animal Behavior-Related Research And Teaching Activities In North American Agricultural And Veterinary Medical Colleges, W. R. Stricklin

Ethology Collection

A letter questionnaire was used to survey animal behavior-related research and teaching efforts in U.S.A. and Canadian university animal sciences departments (agriculture) and veterinary medical colleges. The objectives of the eleven questions of the survey were to identify behavior workers and to determine the current and planned levels of emphasis on research and teaching activities in domestic animal behavior. During 1981, questionnaires were mailed to 162 deans and chairmen, and 102 were answered and returned. Twenty-three persons were identified as having appointments specifically or primarily in animal behavior, and 99 persons were identified as having appointments that had some responsibilities …

The Ld50--The Beginning Of The End, Andrew N. Rowan

Experimentation Collection

Measurement is very important in science. Early lessons in the science classroom involve teaching students to measure lengths, volumes, weights, specific gravities and anything else within the mental and economic compass of the teacher. At the same time, the question of significance is drummed into the students' heads. Thus, if one has a meter-rule which is subdivided into centimeters (but not millimeters), one is taught that the measurement of its length to one decimal point (for example, 10.3 em) is acceptable, but that the addition of any more figures (for example, 10.325 em) is mere braggadocio. The eye can only …

Vivisection And Misanthropy, George P. Cave

Experimentation Collection

Goodman recognizes that it is reasonable to question whether all experiments performed on animals really contribute to human welfare, and he even concedes that the use of animals in laboratories "could no doubt be reduced further without harm to humankind." On the other hand, it is quite clear that he is completely unaware of the sheer quantity of absolutely worthless experiments currently being conducted, ,and that he subscribes to the popular misconception, deliberately perpetrated by the research establishment, that animal experimentation is coextensive with biomedical research, thereby contributing directly to human welfare through the conquering of disease. Furthermore, Goodman seems …

The Potential Role Of Local Ethical Committees In The Moderation Of Experiments On Animals In Britain, D. P. Britt

Experimentation Collection

Scientists working with laboratory animals in Britain are made aware forcibly that a serious ethical dilemma surrounds the use of animals in experiments. Certain vociferous sections of the community press the issue on the attention of the general public and media sources tend to propagate views expressed by the most extreme parties, while neglecting coverage of mature, rational opinion. It is, perhaps no bad thing for the scientific community to be frequently reminded to take a responsible attitude to the use of animals but recent overt, even illegal, activity on the part of extremist animal protectionist groups has encouraged a …
