Mineral-Deficient Diets And The Pig’S Attraction To Blood: Implications For Tail-Biting, David Fraser

Abnormal Behavior Collection

In two experiments, individually penned growing pigs were exposed daily to two "tail models” (lengths of cotton cord about the size of a pig's tail), one of which had been impregnated with pigs' blood. When fed a balanced "control" diet, the pigs chewed significantly more on the blood-covered model than on the plain one, but with Iarge individual differences between animals. Four weeks of receiving a diet lacking all mineral supplements (iodized salt, dicalcium phosphate, limestone, iron, zinc, manganese, copper, and selenium) caused a pronounced increase in chewing the blood-covered model, and 4 wk of recovery on the control diet …

Attraction To Blood As A Factor In Tail-Biting By Pigs, David Fraser

Abnormal Behavior Collection

Canvas models, about the size of a pig's tail, were impregnated with pigs' blood or left plain, and were presented to pigs for 12 days in a 2-choice preference test. The pigs showed large, consistent, individual differences in response: some pigs chewed the models continuously while others chewed only slightly; some chewed much more on the blood-covered model, while others showed no preference. On average, the pigs chewed considerably more on the blood-covered model than on the plain one. In a second experiment, pigs presented with a choice test involving a blood-covered and a plain model showed a significant increase …

The Movement Action Plan: A Strategic Framework Describing The Eight Stages Of Successful Social Movements, Bill Moyer

Strategy and Social Movements Collection

Social movements are collective actions in which the populace is alerted, educated, and mobilized, over years and decades, to challenge the powerholders and the whole society to redress social problems or grievances and restore critical social values. By involving the populace directly in the political process, social movements also foster the concept of government of, by, and for the people. The power of movements is directly proportional to the forcefulness with which the grassroots exert their discontent and demand change. The central issue of social movements, therefore, is the struggle between the movement and the powerholders to win the hearts …

Cardiac Correlates Of Individual Recognition In The Chimpanzee (Pan Troglodytes), Sarah T. Boysen, Gary G. Berntson

Sentience Collection

The ability of a chimpanzee to recognize individuals depicted in photographs was evaluated through the use of heart rate measures. Heart rate was recorded before and during photographic projections of human caregivers, familiar individuals, strangers, and blank control slides. In the absence of explicit training or reinforcement, the chimpanzee displayed a differential pattern of heart rate response to the stimulus categories. Although heart rate responses to all stimuli were predominantly deceleratory, the photographs of caregivers yielded consistently larger responses than other stimuli. Results indicate that the chimpanzee is able to recognize individual humans from novel photographic representations and that heart …

Dogfighters On The Run: The Hsus Spurs Police Crackdown

Close Up Reports

How can anyone derive satisfaction from watching two dogs tear each other apart? How can anyone sit for hours, not only watching but cheering every wound, every broken leg or mangled eye?

We can only guess the answers to such questions. What we do know is that every weekend, hundreds of men, women, and children attend dogfights, enjoying the blood and excitement of dogs matched to the death and even wagering on the outcome. Virtually anyplace--a vacant garage, warehouse, apartment building basement, or city park--can house a dog pit. A picturesque farmhouse or barn may hold hundreds of spectators brought …

Variation In Piglet Weights: Development Of Within-Litter Variation Over A 5-Week Lactation And Effect Of Farrowing Crate Design, B. K. Thompson, D. Fraser

Ontogeny Collection

Piglets from 51 litters were weighed weekly over a 5-wk lactation in an experiment that studied the effects of farrowing crate design and other factors on variation in piglet weight. Of two farrowing crates used, one had low horizontal bars that tended to impede access to the upper row of teats, while the other had angled vertical bars which permitted freer access. Fourteen-day weights were more uniform in the vertical-bar crates than in the horizontal-bar crates (P < 0.025), but the difference waned by day 35 (P > 0.05). There were no significant differences in mean body weight owing to crate type (P < 0.05) for any of the weekly measurements but, by day 14, there was a significant linear trend (P < 0.05) at decreasing main body weight with increasing litter size. The interaction between crate type and litter size was significant at the later ages (P < 0.01 at day 35) because the linear trend was more pronounced for horizontal-bar crates than for vertical. Litters differed greatly in the uniformity of their body weights. Much of the variation became established in the first and, to a lesser extent, the second week after birth. In those weeks, weight gains were highly variable and were not closely related to weight at the beginning of the week. Thereafter, the established differences tended to be perpetuated to 35 d, because weight gains were largely proportional to body weight. Within-litter competition appeared to influence weight gain considerably.

Trapping Agony Continues: The Hsus Fights To End The Anguish

Close Up Reports

Despite the fact that the steel-jaw leghold trap has been outlawed in dozens of civilized nations, each year in the United States, its vicious jaws maim and kill an estimated 15 million animals. For wild creatures that have no owners awaiting their return, their cries of anguish go unheard and unanswered.

Variation In Piglet Weights: Relationship To Suckling Behavior, Parity Number And Farrowing Crate Design, David Fraser, B. K. Thompson

Ontogeny Collection

Suckling behavior and weight change of piglets were studied during the first 2 wk after birth. Thirty-six litters comprised a balanced comparison of parity number (first or second), litter size (8, 10 or 12), and two farrowing crate designs, one of which had a low horizontal bar that tended to impede the piglets' access to the udder. Piglets showed the expected preference for the anterior teats although the preference was more apparent in the second parity than in the first. Teat fidelity was most pronounced at the two ends of the udder; piglets occupying the middle positions did more fighting …

A Case Against Animal Rights, Jan Narveson

Animal Welfare Collection

Down through the past decade and more, no philosophical writer has taken a greater interest in the issues of how we ought to act in relation to animals, nor pressed more strongly the case for according them rights, than has Tom Regan, in many articles, reviews, and exchanges at scholarly conferences and in print. It is a pleasure to join him on this symposium, to explore this interesting and important set of issues.

I shall begin by outlining, as fairly as I can, Regan's view of the matter, and then sketch my alternative. Regan has in fact criticized certain aspects …

The Case Against The Use Of Animals In Science, Donald J. Barnes

Experimentation Collection

As a scientist long committed to the understanding, prediction, and control of biological, physiological, and behavioral events, I have no objection to the animal as a legitimate focus of science. As a parent, a son, a sibling, and the proud recipient of unconditional positive regard from a few special people, I am vitally interested in matters of health and in the most ethically efficient use of available resources. As a member of a species which has evolved sufficiently to allow the relatively broad perspective of a "web of life" and at least a rudimentary concept of altruism, I have laboriously …

The Case For The Use Of Animals In Science, James A. Will

Experimentation Collection

Animals are now used extensively in research and teaching, and the appropriateness of their use appears to be questioned. Some people believe that we are in a new era where the animal activists have become much more influential, and that the antagonism between the scientists and these groups is worse than it ever has been. This does not appear to be the case. The preeminence of various influences seems rather cyclic, even perhaps influenced by such things as economic conditions or wars. At present, the question is often asked, "Should we continue to use animals in science?" The real question …

The Case For The Use Of Animals In Medicine, Gary F. Merrill

Experimentation Collection

The use of animals in medical research and teaching, and the public concern this has generated is not a new issue (Visscher 1969). Ever since scientists began using animals to investigate the function of the body in health and disease, there have been those who opposed their work (Fishman and Richards 1982). Whether this controversy is cyclic is not known, but most concerned biomedical investigators agree that the opposition is here to stay. The author shares this opinion, and thus maintains that it is in the best interest of all parties to be properly educated on the issues. Only through …

The Case For Hunting On National Wildlife Refuges, Harvey K. Nelson

Hunting Collection

Public land management agencies are faced with greater challenges today than ever before in responding to the recreational needs of society. As Will Rogers so aptly stated, "Land, they make so little of it nowadays" (Steinhart 1986). The U.S. Fish and Wildlife Service (FWS) also must face these challenges in management of national wildlife refuges (NWRs). There is a growing demand by the American people to utilize and enjoy NWRs in a variety of ways. Managers are faced with the dilemma of determining how much and what kind of management and utilization of natural resources is appropriate without compromising the …

Contribution To A Concept Of Behavioral Abnormality In Farm Animals Under Confinement, U. A. Luescher, J. F. Hurnik

Agribusiness Collection

Farm animals housed in close confinement often engage in activities that do not occur with animals maintained in traditional and more complex environments. Many of these activities consist of species-typical motor patterns directed towards unsuited or inappropriate objects, or performed as vacuum activities. For example, piglets fed from a trough from day 2 to day 21 after parturition display much nosing. of penmates and ear sucking (DeBoer and Hurnik 1984). Similarly, confined veal calves in crates may lick their pelage excessively, or, when housed in groups, may suck the naval area of penmates; laying hens and broilers often engage in …

Providing Humane Stewardship For Wildlife: The Case Against Sport Hunting, John W. Grandy

Hunting Collection

Sport hunting has no place on the National Wildlife Refuges of this nation. To even consider it is an affront to the concept of a Refuge, the right of wild animals to safe haven, and the wishes of society The question of sport hunting in society at large is slightly more complex because society, its thoughts and values, are evolving. Thankfully, we are moving more and more to a view that wildlife should be treated with the same dignity, respect, and freedom from avoidable cruelty that we would ask for ourselves. That process can be moved miles ahead if we …

The Case For Hunting, William L. Robinson

Hunting Collection

My purpose at this symposium is to present the case for hunting. I am a wildlife ecologist by training and profession, and I am also a hunter. As a hunter, I am sensitive to criticisms of this pursuit, as any hunter should be. Some people question how, with knowledge of the nature and functioning of ecological systems, I can go out with a gun and kill grouse, ducks, and deer. I respond that, indeed, my understanding of ecology and the nature of man enhances my enjoyment of hunting.

The Case For Intensive Farming Of Food Animals, Stanley E. Curtis

Agribusiness Collection

Our world is still a hungry place. At the same time, the number of people worldwide who grow food for themselves continues to dwindle. Most U.S. citizens have never set foot on a farm or harvested one mouthful-let alone a lifetime's worth-of daily bread. Yet our farmlands and climates and our agricultural and food industries are this nation's ultimate resources. By increasing productivity, our farmers and the scientific and business endeavors that support our nation's food production, processing, and distribution have proved to be able and reliable husbands of these precious resources. But make no mistake: The challenge to increase …

Effects Of Early Experience Upon Adaptiveness Of Horses, J. C. Heird, R. W. Bell, S. G. Brazier

Equines Collection

Experimentation with laboratory animals, encompassing the range of usual species (mice, rats, cats, clogs, and primates), has conclusively demonstrated that handling by humans during early life facilitates subsequent development in terms of health and viability, reduced emotional reactivity, more adaptive responses to a variety of stressors (both biological and behavioral adaptations), and increased ability to adapt to changing circumstances as exemplified by increased ability to learn and solve problems (seeM. Bornstein 1985, for recent review).

Two studies (described below) (Heircl et a!. 1981; Whitaker 1982) conducted at Texas Tech University (TTU) have extended these findings regarding the beneficial effects of …

Human/Farm Animal Relationships, Jack L. Albright

Agribusiness Collection

There are various combinations of human beings and farm animals. This paper attempts to evaluate those few studies of humans handling farm animals within a prescribed environment. Personality traits of dairy farmers and livestock people as determined by the Eysenck Personality Inventory (Eysenck 1977) need further study (Seabrook 1974; Arave and Brown 1979). Seabrook's sample size was small (20 herds) and these herds were criticized for having low yields while Arave and Brown's questionnaire did not go far enough.

The Case Against Intensive Farming Of Food Animals, Linda D. Mickley, Michael W. Fox

Agribusiness Collection

The well-being of American agriculture is indeed a complex subject, fraught with interrelationships, predictions, recriminations, and at times, high emotionalism. In this paper, we will be concentrating on several aspects of the entire picture that we feel are fundamental to the issue of animal welfare in modern agriculture. First, we will take a brief look at two farm animal species maintained in very restrictive systems, that is, battery-caged laying hens and tethered and/or crated brood sows.

Next, the human costs in terms of occupational diseases and consumer health hazards will be considered. Finally, some humane alternatives to the factory systems …

Horsebreakers, Tamers, And Trainers: An Historical, Psychological, And Social Review, Sharon E. Cregier

Equines Collection

To my knowledge, there has been no organized synthesis describing the historical development of horse handling, management, lore, and training. This discussion offers, in capsule form, some of the historical, psychological, and social considerations which might be taken into account when evaluating horse-handling skills.

First, I would like to describe the natures of the emotional and psychological bonds between man and horse. I will also look at the consequences of various types of bonding on horsemanship or management. We can increase our understanding of the role of the horse in our history and lives by thus seeing how the animal …

Wildlife And Nature Liberation, Michael W. Fox

Conservation Collection

Humane ethics--animal welfare--and animal rights are not incompatible with ecologically sound wildlife stewardship. They are an integral part of it, from treating wildlife for necessary research purposes humanely, to finding humane ways to control the populations of species that are out of balance and thus threatening the viability of other species and the diversity and integrity of the ecosystem. That mistakes may be made in stewardshipmanagement policies is inevitable. It is, for instance, difficult to know if the sudden abundance of one or more species and the dwindling of others is part of the natural process of succession and should …
