Farm Animal Welfare And Human Health, Alan M. Goldberg

Agribusiness Collection

The paper examines the relationship between farm animal welfare, industrial farm animal production, and human health consequences. The data suggest that when the animal welfare of land-based farm animals is compromised, there are resulting significant negative human health consequences due to environmental degradation, the use of non-therapeutic levels of antibiotics for growth promotion, and the consequences of intensification. This paper accepts that even if meat and fish consumption is reduced, meat and fish will be part of the diet of the future. Industrial production modified from the current intensified systems will still be required to feed the world in 2050 …

Understanding Mortality Rates Of Laying Hens In Cage-Free Egg Production Systems, The Humane Society Of The United States

Agribusiness Collection

In cage-free egg production systems, concerns have been raised over hen mortality rates. High mortality is an obvious indicator of poor welfare, and problems should be addressed without delay. It is important to note, however, that mortality can vary substantially between hen flocks, and that some cage-free systems have healthy flocks that do not suffer substantial death losses. These systems can serve as models for the rest of the industry, since mortality is not inherent to any particular system, but a consequence of how well the system is managed.

Global Farm Animal Production And Global Warming: Impacting And Mitigating Climate Change, Gowri Koneswaran, Danielle Nierenberg

Agribusiness Collection

BACKGROUND: The farm animal sector is the single largest anthropogenic user of land, contributing to many environmental problems, including global warming and climate change.

OBJECTIVES: The aim of this study was to synthesize and expand upon existing data on the contribution of farm animal production to climate change.

METHODS: We analyzed the scientific literature on farm animal production and documented greenhouse gas (GHG) emissions, as well as various mitigation strategies.

DISCUSSIONS: An analysis of meat, egg, and milk production encompasses not only the direct rearing and slaughtering of animals, but also grain and fertilizer production for animal feed, waste storage …

The Long Haul: Risks Associated With Livestock Transport, Michael Greger

Agribusiness Collection

The Food and Agriculture Organization (FAO) of the United Nations describes live animal transport as “ideally suited for spreading disease,” given that animals may originate from different herds or flocks and are “confined together for long periods in a poorly ventilated stressful environment.” Given the associated “serious animal and public health problems,” the Federation of Veterinarians of Europe has called for the replacement of the long-distance transportation of live animals for slaughter as much as possible to a “carcass-only trade.”

In the United States, more than 50 million live cattle, sheep, and pigs and an unknown number of the more …

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 …

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 …

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 …

The Attainment Of Humane Housing For Farm Livestock, D.G.M. Wood-Gush

Agribusiness Collection

In discussing animal welfare it is very easy for the discussion to become bogged down by misunderstandings. Commonly the first misunderstanding arises over the definition of animal welfare. In the content of this article we will take it for granted that any definition includes the physical well-being of the animal as well as ensuring that the animal can fulfill much of its genetically controlled behavioral repertoire. The second misunderstanding arises when the political and scientific assessments of the subject are meshed together. In a scientific assessment, the aim should be to examine welfare problems strictly from what we know about …

Cardiac Arrest Stunning Of Livestock And Poultry, Temple Grandin

Agribusiness Collection

A stunning method that will reliably render an animal insensible to pain and sensation prior to hoisting and bleeding is essential to prevent suffering. Cardiac arrest stunning is more effective than conventional electric stunning. In cardiac arrest stunning, an electric current is passed through both the brain and the heart to produce permanent insensibility. Since the animal is killed by the electricity it cannot revive during hoisting, bleeding, or slaughtering procedures. In contrast, conventional electrical stunning induces reversible insensibility for a short period of time.

The Definition, Current Knowledge And Implementation Of Welfare For Farm Animals--A Personal View, Ron Kilgour

Agribusiness Collection

Being humane to farm animals (welfare) must include (1) having a sound knowledge of their normal and anomalous behavior responses in a farm context and heeding this in a practical way and (2) adopting handling procedures which elicit minimal distress in the species concerned. Building up an ethogram of predictable responses and recording the patterns of behavior during key events, mating, birth, and care of the young are essential. There are still gaps in the recorded ethograms offarm animals. Objective measurements of distress, including an index of its seriousness, are also a priority.

The results from animal preference tests can …

Stereotype Behaviour In Sows And Gilts Housed In Stalls, Tethers, And Groups, Judith K. Blackshaw, J. F. Mcveigh

Agribusiness Collection

Observations of sows and gilts in tethers, stalls, and groups showed two distinct types of behaviour: pre-feed behaviour when pigs were anticipating food, and after-feed behaviour. Sows and gilts tethered for the first time do not show pre-feed excitement, but this develops in 42 days which suggests that pre-feed behaviour is not stereotype, as suggested by the literature, but is a conditioned reflex.

The question of the importance of after-feeding behaviours which are often called stereotypies is examined. The total time occupied by these behaviours over 24 hours by tethered sows is 14.5 to 29.0%, by tethered gilts 1.4 to …

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

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 …

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 …

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 …

Farm Animal Welfare: Some Opinions, Michael W. Fox

Agribusiness Collection

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 as well as a large number of articles in professional and popular magazines. Three international symposia dealing with animal rights have been held in the last two years and a major European conference dealing with farm animal welfare and involving veterinarians, farmers, animal scientists and animal welfare groups was held in Amsterdam in 1979.

In the U.K., a governmental Farm Animal Welfare …

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.

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 …

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 …

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.

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.
