Psychological Aspects Of Slaughter: Reactions Of College Students To Killing And Butchering Cattle And Hogs, Harold A. Herzog, Sandy Mcgee

International Journal for the Study of Animal Problems

This study examined college students' reactions to slaughtering cattle and hogs as part of their jobs on a college work crew. The 27 students were surveyed on attitudes containing items toward slaughtering animals and toward different uses of animals. Nineteen were later interviewed. Some aspects of slaughtering were reported to be more bothersome than others. There was a relationship between the subjects' experience in slaughtering, general attitudes toward various uses of animals, and their responses to several of the items on the questionnaire. The perceived benefits of the slaughtering experience and the justification for killing domestic animals for food are …

The Behavior Of Confined Calves Raised For Veal: Are These Animals Distressed?, M. Kiley-Worthington

International Journal for the Study of Animal Problems

The behavior of twelve calves confined in crates was recorded at 1-minute intervals for 12-hour periods. These recordings were made at fortnightly intervals from approximately 2 to 16 weeks of age. In all, 864 hours of observations were recorded. The activities performed and the amount of time spent doing each are outlined. Circadian rhythms were mainly controlled by feeding time, although there was a difference between diurnal and nocturnal behavior. Individual calves varied in how they adapted to the restricted environment. Individual personality profiles and data on the ontogeny of behavior under these conditions are presented. At ten weeks of …

The Agricide Treadmill And Farm Animal Welfare, Michael W. Fox

International Journal for the Study of Animal Problems

The author cites publications that argue that agriculture in the United States is on a treadmill where farmers continually compete to reduce their food production costs. The consequence has been a reduction in farm animal welfare.

Prostaglandin F2a Induced Nest Building Behavior In The Non-Pregnant Sow, And Some Welfare Considerations, Judith K. Blackshaw

International Journal for the Study of Animal Problems

Nest-building behavior, induced with intramuscular injections of prostaglandin F2a (PGF2a), was studied in non-pregnant sows. Acute effects were also recorded, including salivation, scratching, vomiting, defecation, and ataxia. Sows (Large White x Landrace) were housed in two different environments; six in bare pens and six in pens provided with bedding material. All cases except one (bare pen) nest-building sequences of differing intensities were recorded. Welfare suggestions include questioning the justification of using a drug (PGF2a) in pig husbandry, which has unpleasant acute effects, and the suggestion that the provision of bedding material is not necessary for a nest-building sequence to occur.

Review Of Literature On Use Of T-61 As An Euthanasic Agent, Laaura Dalia Barocio

International Journal for the Study of Animal Problems

The available evidence indicates many questions about T-61 as a satisfactory euthanasia agent. The only controlled study of animal E EG's after T-61 administration showed that this compound could produce rapid unconsciousness. However, the drug was administered via an indwelling catheter which is not generally used in shelters euthanizing 10,000 to 20,000 animals a year. Furthermore, the investigator compared the T-61 results against the results obtained with a weak and marginally lethal dose of sodium pentobarbital.

Ethologic And Economic Examination Of Aviary Housing For Commercial Laying Flocks, D. W. Folsch, Chr. Dolf, T. Bleuler, H. Ehrbar

International Journal for the Study of Animal Problems

The authors report that the results of their research indicate that appropriate housing is necessary for intensively kept hens and that the housing has to correspond to the vital needs and natures of the animals.

Occlusion Of Vision In Old English Sheepdogs, Michael W. Fox

Veterinary Science and Medicine Collection

The show standards established for many breeds of dogs have been linked with a number of genetically related abnormalities that can result in unnecessary suffering. The facial skin folds and shortened face of bulldogs, which respectively lead to chronic dermatitis and respiratory difficulties, are two dramatic examples. Likewise, ear-cropping is an ethically questionable mutilation that conveys no benefit upon the dog. Another serious welfare concern relates to a practice that is common among owners of Old English sheepdogs and other breeds with long facial hair: allowing the hair to cover the animal's eyes. This feature is considered a desirable show …

Aquaculture--Now, Factory Fish Farming, Michael W. Fox

Aquaculture Collection

"Aquaculture 1983" was the title of a 5-day symposium and industry exhibit held in Washington, D.C., on january 9- 13,1983, sponsored by World Mariculture Society, Catfish Farmers of America, Fish Culture Section of the American Fisheries Society, U.S. Trout Farmers Association, Shellfish Institute of North America, and National Shellfisheries Association. While ecologists, economists, futurologists, and others have touted the virtues and potentials of intensive fish and shellfish farm- · ing, this growing industry in the U.S. may become blighted by the same problems that have come to afflict agribusiness' "factory farming" of crops, livestock, and poultry.

Too Much Of A Good Thing: Protein And A Dog's Diet, Dana H. Murphy

Pets Collection

Where the analysis done by Kronfeld on stress in dogs goes awry is in its implication that this conversion of protein reserves occurs during a mild or transient period of emotional turmoil. In point of fact, catabolism of proteins only begins after an extended duration of severe stress, as a consequence of an extreme condition like a long sled race or a bad infection. Therefore, a mildly stressed animal probably needs carbohydrates (and perhaps fats) far more than supplemental protein, since the former can be quickly and easily converted into bodily fuel. And in the case of the stress induced …

Genetic Adaptation And Welfare, J. Van Rooijen

Genetics Collection

Beilharz says: "The evolutionary processes, if they are not obstructed or misdirected, must lead to such a degree of adaptation that welfare will have to be taken for granted, just as we can do no better than to take for granted the welfare of any wild animal in its natural habitat." From this statement, one might conclude all we have to do is wait, and the animals will eventually adapt to intensive systems. Concerning animals put into new kinds of environments, he states that, if individuals do not have the capacity to adjust phenotypically, "adaptation of the population will require …

Selecting A Spay/Neuter Program For Animal Control In The City Of Charlotte, Diane Quisenberry, Mary Elizabeth Clapp

Hunting Collection

The City of Charlotte, NC, in attempting to determine the best kind of program for reducing its increasing populations of unwanted dogs and cats, examined a full range of possible options for limiting these populations. Five measures for population control were considered: spay/neuter surgery, euthanasia, physical restraint, mechanical contraception, and chemical contraception. It was concluded that a spay/neuter program that incorporated educational and legislative components would be the most effective means of large-scale population control, although other methods like euthanasia would still have to be used. Based on a survey of a number of cities with spay/neuter programs in place, …

Review Of Literature On Use Of T-61 As An Euthanasic Agent, Laura Dalia Barocio

Veterinary Science and Medicine Collection

The tools of evaluating the degree of distress in animals being killed include electroencephalography (EEG), electrocardiography (ECG), and measurement of blood pressure and respiration. Sound clinical and behavioral observations should also not be abandoned in the evaIuation process.

There are many methods which may be employed to reach the same end results, but the ideal method should satisfy several criteria: 1. It should be painless; 2. It should cause unconsciousness instantaneously and death within minutes; 3. It should not cause undue anxiety, alarm, fear, panic, behavior, struggling, vocalization, muscle spasms or clinical signs of automatic activation (e.g., convulsions) before unconsciousness; …

Report No 58 - 1982 - Review Of Rainfall And Wetlands In The South-West Of Western Australia, J. A.K. Lane, D. R. Munro

Fisheries Research Reports

An account is given of involved the biological principles in decisions concerning duck-shooting seasons in the south-west of western Australia.

Conditions for waterfowl during 1982 are described through the use of rainfall statistics and data obtained from the Department's wetland monitoring programme.

1982 was characterized by exceptionally high rainfall in January and well-below average from February to October.

1982 was the seventh consecutive year of below-average rainfall in all five Meteorological of the south-west. 1976 to 1982 has thus been the south-west's driest seven-year period for more than seventy years.

The record-breaking rains of January caused widespread flooding in the …

Furunculosis And Other Diseases Caused By Aeromonas Salmonicida, G. L. Bullock, R. C. Cipriano, S. F. Snieszko

United States Fish and Wildlife Service: Publications

Aeromonas salmonicida is a gram-negative bacterium that usually produces a water-soluble brown pigment. It was first described by Emmerich and Weibel (1890) as the cause of salmonid furunculosis in Germany. Although the disease was first considered to be limited to salmonids, studies by the Furunculosis Committee (Mackie et al. 1930, 1933, 1935) showed that A. salmonicida also infected other fish species. Present indications are that A. salmonicida or its variants also produce other diseases, such as ulcerative disease of goldfish (Carassius auratus), erythrodermatitis of common carp (Cyprinus carpio), ulcer disease of trout, and systemic infections among …

Infectious Pancreatic Necrosis (Ipn) Of Salmonid Fishes, Phillip E. Mcallister

United States Fish and Wildlife Service: Publications

Infectious pancreatic necrosis (IPN) is a viral disease principally associated with salmonids, although IPN and lPN-like viruses have been isolated from various nonsa1rnonid fish and marine invertebrates. Acute infection occurs in 1- to 4-month-old salmonids and can result in cumulative mortality approaching 100%. In contrast, fish 6 months old or older can undergo subclinical or inapparent infection, but experience no significant mortality. Survivors of the disease can become lifelong carriers of the virus. Epizootics of IPN have been reported worldwide, and several virus serotypes are recognized. The disease known as IPN was probably first described by M'Gonigle (1941) as acute …

Ubersicht Der Ergebnisse Der Ungarischen Zoologischen Expeditionen In Der Mongolischen Volksrepublik 1963-1968, Zoltan Kaszab

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Die Fauna der Mongolischen Volksrepublik war bis zu den 60er Jahren unseres Jahrhunderts fast unbekannt geblieben. Eine Ausnahme ist die Wirbeltierfauna, welche vor allem von russischen Zoologen gründlich erforscht und deren Resultate publiziert wurden. Dagegen hatten wir von den Wirbellosen nur spärliche Angaben in der Literatur, welche teils auf der Sammeltätigkeit russischer Forscher beruhen. Von ungarischer Seite war nur eine Expedition an der Jahrhundertwende (1898) von dem Grafen Eugen ZICHY durchgeführt worden, und während der kurzen Durchreise (3. bis 15. September) in der Mongolei hat sein Begleiter E. CSIKI, damaliger Kustos der Zoologischen Abteilung des Ungarischen Nationalmuseums, ein abwechslungsreiches zoologisches …

Cranes Of The World: 5. Comparative Reproductive Biology, Paul A. Johnsgard

Cranes of the World by Paul A. Johnsgard

The reproductive biologies of cranes are surprisingly similar. All crane species are strictly monogamous, have long pair bonds and a prolonged period of juvenile dependency, and are highly territorial during the breeding season. All cranes also have an extremely limited reproductive potential, resulting from their deferred sexual maturity, low clutch size, and limited renesting tendencies following the loss of a clutch or hatched young.

Then soare from ground not past a yard or two,
Till in their wings they gathered have the winde;
At last they mount the very cloudes unto,
Trianglewise according to their kind.

Cranes Of The World: 6. Aviculture And Hybridization, Paul A. Johnsgard

Cranes of the World by Paul A. Johnsgard

The keeping of cranes in captivity, either as pets or as animals to be fattened for the pot, is evidently a very old practice. Captive cranes are depicted on the walls of the Temple of Deir-el-Barari of the Nile Valley, where cranes are shown walking in stately fashion between slaves. Each crane's bill is tied down close to its neck, which would upset its balance and thus prevent it from flying away (Whymper, 1909). Armstrong (1979) noted that cranes were apparently domesticated in ancient Greece, and that Plutarch (c. A.D. 46-c. A.D. 120) mentions the nesting of tame cranes, presumably …

Cranes Of The World: 1. Classification And Evolution, Paul A. Johnsgard

Cranes of the World by Paul A. Johnsgard

Cranes and their relatives the limpkins and trumpeters are fairly closely related members of the order of birds (Gruiformes) that also includes rails, gallinules, coots, and other marsh-adapted birds. Cranes, limpkins, and trumpeters are usually included within a superfamily, Gruoidea, although at least one recent authority (Cracraft, 1973) has suggested that the three groups all be included within a single family, Gruidae. However, traditionally only the cranes have been included within the Gruidae, and only the cranes will be dealt with in detail in this book. Nevertheless, the limpkins and trumpeters must be considered if the evolution of cranes is …
