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

Agribusiness Collection

Nest building behavior, induced with intramuscular injections of prostaglandin F2_a (PGF2_a), was studied in non-pregnant sows. Acute effects, which included salivation, scratching, vomiting, defaecation and ataxia, were also recorded. Sows (Large White x Landrace) were housed in two different environments; six sows in bare pens and six sows in pens provided with bedding material. In all cases except one (bare pen) nest building sequences of differing intensities were recorded. Welfare suggestions include questioning the justification of using a drug (PGF2_a) in pig husbandry, which has unpleasant acute effects, and the suggestion that the provision of …

The Economics Of Farm Animal Welfare, A. J. F. Webster

Agribusiness Collection

The number of ways that one can be nice or nasty to animals are legion. This article will consider only one very specific aspect of farm animal welfare, namely, those systems of intensive animal production in which the system itself, irrespective of the quality of the stockmanship within the system, appears to restrict the normal behavior of farm animals to an unacceptable degree. The systems that were considered by the House of Commons Select Committee on Agriculure (1981) include egg production from hens in battery cages, production of veal from calves deprived of solid food and isolated in wooden crates, …

Farm Animal Welfare: Some Economic Considerations, Frances Turner, John Strak

International Journal for the Study of Animal Problems

There has been increasing public concern in the U.K. and other European countries about some of the intensive methods of livestock production used in modern agriculture. The battery system of egg production, which produces almost all of the eggs consumed in Britain, has aroused particular opposition, but there is also strong feeling about housing systems that effectively immobilize their inhabitants, such as certain types of veal calf and pig rearing units. In a recent test case in West Germany, an egg producer was charged with "continuous cruelty" to his 60,000-strong battery flock. A high court decided it was cruel to …

Farm Animal Welfare: Some Opinions, Michael W. Fox

International Journal for the Study of Animal Problems

The subject of farm animal welfare has evoked a wide range of responses from those involved in the livestock industry and those concerned about the humaneness of intensive husbandry farming practices. Books have been published

on the subject (Harrison, 1964; Mason & Singer, 1980; Dawkins, 1980, and Fox, 1980 and 1981), as well as many articles in professional and popular magazines. Three international symposia dealing with animal rights have

been held in the last two years (Lehman, 1980; Miller, 1981; Paterson and Ryder, 1980), and a major European conference dealing with farm animal welfare and involving veterinarians, farmers, animal scientists, …

Farm Animal Welfare: Some Economic Considerations, Frances Turner, John Strak

Agribusiness Collection

Farmers, just like other businessmen, attempt to produce a saleable product at the least possible cost to themselves. In this way they hope to assure themselves of some profit, and hence to earn a living. In itself this profit motive cannot be criticized, but in attempting to maintain their profits, farmers have adopted more intensive systems of animal production. In turn, the benefits from farmers using these new techniques have accrued to consumers in the form of relatively less expensive food. Clearly, by restricting the use of factory farming methods (which are associated with lower unit costs of production) there …

Euthanasia Of Day-Old Male Chicks In The Poultry Industry, Walter Jaksch

Agribusiness Collection

Humane killing of animals implies a painless death (euthanasia). This depends on the rapidity with which unconsciousness is achieved and the maintenance of this state until death occurs. Euthanasia methods for day-old chicks must also be economical and should not interfere with the use of the carcasses for animal food or fertilizer. Manual decapitation or dislocation of the neck are the best available manual methods of euthanasia. For larger numbers of birds, the literature recommends homogenization in a crusher. In the author's own experiments, the destruction of day-old chicks was most effectively carried out by poisoning with carbon dioxide (CO …

One Answer To The Confinement Pig Problem, Arthur Nehring

Human Health Collection

A new design for an intensive hog finishing operation is presented. The "maze deconfinement" system consists of a series of 4-walled concrete pens arranged in a T-maze within a confinement building that is designed to utilize solar energy. In addition to low cost and efficient use of energy, the system has the following advantages: higher feed conversion rate; less fighting among and injuries to hogs; some freedom for hogs to exercise and explore; decreased labor. The system has been in use on the author's farm since the end of 1976.

The Buller-Steer Syndrome, Richard Ulbrich

Ethology Collection

Bulling among steers is an abnormal behavioral trait and is a common health and economic problem in feedlot operations. Factors associated with the buller-steer syndrome are hormonal implantation, seasonality and environmental conditions, stress, overcrowding, and social interaction between individuals. Research has examined relationships between these and other factors and buller occurrence. Boredom of feedlot cattle may contribute to buller occurrence and other undesirable behavior more than we might suspect. Research is needed to determine the feasibility of enriching the environment of penned livestock in general, the goal of which would be, in theory, the elimination of undesirable behavior as well …

Productivity And Farm Animal Welfare, Michael W. Fox

Agribusiness Collection

In the search for and debate over objective indices of farm animal welfare, productivity is regarded by many animal scientists and others in the livestock industry as the most reliable measure of an animal's overall well-being and adaptability. On the surface, this would seem to be so, as productivity--in terms of growth rate, milk yield, feed-conversion and egg production--can be easily quantified. However, there are serious flaws in this assumption.

Behavior And Weight Loss Of Feeder Calves In A Railcar Modified For Feeding And Watering In Transit, T. H. Friend, M. R. Irwin, A. J. Sharp, B. H. Ashby, G. B. Thompson, W. A. Bailey

Agribusiness Collection

The behavior of 164kg Angus and Hereford calves was studied in a double deck 26m x 2.6m "jumbo" railcar equipped with feed and water. A 4,180 liter water tank positioned in the center of each deck divided the car into four compartments. Fifty head were loaded into the lower and upper forward compartment (252kg/m²floor space], each containing 675kg of hay in racks. The two rear compartments served as quarters for equipment and researchers. Two video cameras were mounted in the upper forward compartment containing calves. Behavior of the calves was monitored, with portions video taped during rail transport …

The Involvement Of The Farm Animal Veterinarian In Animal Welfare, David G. Llewellyn

Veterinary Science and Medicine Collection

The farm animal practitioner has always played a dual role. The primary role is humanitarian, concerned with the well-being of the livestock, and the secondary role relates to the economics of the enterprise.

Livestock Behavior As Related To Handling Facilities Design, Temple Grandin

Agribusiness Collection

A knowledge of the behavior of different species of livestock as well as different breeds within a particular species is essential to the proper planning of a handling facility. An optimal facility should incorporate features which minimize stress on the animal and maximize the efficiency of movement from holding pen to slaughter area. Handler awareness of the animals' perception of critical distance flight zone and personal space requirements also reduces problems with balking and alarm behavior. Many improvements can be made with relative ease, thus enabling already existing facilities to upgrade their operations.

Bruises And Carcass Damage, Temple Grandin

Agribusiness Collection

Bruising and carcass damage is a major source of financial loss to slaughterhouses in the United States, approximately $46 million per annum. The absence of easily administered tests to determine where and/or when bruising occurs results in the slaughter plant absorbing carcass damage costs. Rough, abusive handling of livestock accounts for over half of all bruising. Injuries occur through overuse of persuaders, careless transport methods, and faulty equipment. Other elements relevant to carcass loss include branding cattle, abscesses, spreader and crippling injuries, sickness and death during extreme weather conditions, and carcass shrink. The 1979 regulations under the Humane Methods of …

The Ministry Of Agriculture's Involvement With Animal Welfare, Roy Moss

Agribusiness Collection

Keeping livestock healthy is primarily the responsibility of owners. Indeed, if they did not do so they would certainly not make a profit. Advice on the prevention, treatment and possible cure of disease is the responsibility of the veterinary surgeon. Prevention of physical damage to animals and their adoption of abnormal behavior caused by confinement which prevents them from exercising their inherited behavioral patterns is the joint responsibility of the ethologist, the technologist who designs the confinement system and ancillary equipment, the livestock husbandry specialist, the veterinary surgeon and the owner. If society also decides that there is a need …

Mechanical, Electrical And Anesthetic Stunning Methods For Livestock, Temple Grandin

Agribusiness Collection

A good stunning method must render an animal unable to experience pain and sensation prior to hoisting and slaughter. The three basic types of stunning methods which are classified as being humane (i.e., painless) in the United States, Europe and other foreign countries are captive bolt (penetrating and nonpenetrating), electrical, and C02 (carbon dioxide) gas anesthesia.

The physiological mechanisms of stress are the same before and after the onset of unconsciousness. The release of epinephrine as a result of stress inducers has an effect on the quality of the meat and it is therefore desirable to use a stunning method …

The Psychological Relationship Between Dairy Cows And Dairy Cowmen And Its Implications For Animal Welfare, Martin F. Seabrook

Human and Animal Bonding Collection

While no one could ever say that the conditions for animals and people were ideal in the days of hand milking, the question of animal welfare was less pressing as man was at ease and in balance and harmony with nature. Only as units became larger, and machine milking took the place of the cowman's or dairy maid's hand, did we have to worry about whether man was exploiting this animal species.

The Effect Of Stress On Livestock And Meat Quality Prior To And During Slaughter, Temple Grandin

Agribusiness Collection

The effects of stress on cattle, pigs and sheep prior to slaughter are reviewed. Long-term preslaughter stress, such as fighting, cold weather, fasting and transit, which occurs 12 to 48 hours prior to slaughter depletes muscle glycogen, resulting in meat which has a higher pH, darker color, and is drier. Short-term acute stress, such as excitement or fighting immediately prior to slaughter, produced lactic acid from the breakdown of glycogen. This results in meat which has a lower pH, lighter color, reduced water binding capacity, and is possibly tougher. Psychological stressors, such as excitement and fighting, will often have a …

Problems With Kosher Slaughter, Temple Grandin

Agribusiness Collection

Ritual slaughter to produce kosher meat is rooted in the teachings and writings of the Talmud. However, the preslaughter handling features of modern systems, particularly the shackling and hoisting of large steers, contravene the basic message of humaneness included in the teachings. The throat-cutting of a live, conscious animal is relatively pain-free, provided that certain precautions are followed, but U.S. kosher plants need to install newly developed conveyor-restrainer systems to eliminate the abuses of shackling and hoisting. Conveyor-restrainer systems for large and small animals are discussed.
