A Comparison Of The Welfare Of Hens In Battery Cages And Alternative Systems, Sara Shields, Ian J.H. Duncan

Sara Shields, PhD

Housing systems for egg-laying hens range from small, pasture-based flocks to large, commercial-scale operations that intensively confine tens of thousands of hens indoors. The overwhelming majority of laying hens used for commercial egg production in the United States are confined in battery cages and provided 432.3 cm2 (67 in2) of space per bird. Cages prevent hens from performing the bulk of their natural behavior, including nesting, perching, dustbathing, scratching, foraging, exercising, running, jumping, flying, stretching, wingflapping, and freely walking. Cages also lead to severe disuse osteoporosis due to lack of exercise. Alternative, cage-free systems allow hens to move freely through …

An Hsi Report: The Economics Of Adopting Alternatives To Gestation Crate Confinement Of Sows, Humane Society International

HSI REPORTS

There are a number of significant animal welfare concerns associated with gestation crates for sows, including tangible physical and psychological consequences. Studies document a decrease in muscle weight, bone density, and bone strength due to movement restriction and lack of exercise. Unable to engage in natural rooting and foraging behavior, crated sows often engage in “stereotypic” bar-biting, an abnormal behavior characterized by repeated mouthing movements on the metal rails of the crate. Crated sows also suffer from health problems associated with confinement including a higher rate of urinary tract infections as compared to uncrated sows. Continuous close confinement is a …

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.

An Hsi Report: Adopting A Cage-Free Production Policy For Animal Products In Brazil, Humane Society International

HSI REPORTS

Farm animal welfare is becoming an important concern for governments, producers, and consumers worldwide. In particular, intensive confinement systems, such as battery cages and gestation crates, have been acknowledged as severely impairing to the physical comfort and expression of natural behaviors of animals. The European Union and select states in the United States have already passed bills eliminating these housing systems over the next several years. Numerous international retail and food production companies, including Burger King (North America), Smithfield Foods, and McDonald’s (Europe) are committed to gradually eliminating the use and sale of eggs and pork produced via intensive confinement …

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 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 …

Evils Of Modern Stables, James Irvine Lupton

Equines Collection

Portions of veterinarian James Irvine Lupton's book on horse management that deal with the problems of confinement husbandry practices have been selected as a significant historical record of humane concerns that were documented one hundred years ago. While the author's descriptive prose may lack scientific "objectivity," it does express a common sense morality and the subjective and intuitive observations and conclusions of an experienced veterinarian who clearly respects and understands the horse. His words bespeak of a bygone era where the care or husbandry of animals was both an art and a science, a discipline based upon empathy, compassion and …

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

Ethology Collection

The behavior of 12 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 that were performed and the amount of time spent doing each are outlined. Circadian rhythms were controlled largely by feeding time, although there was a difference between diurnal and nocturnal behavior. Individual calves vaned tn how they adapted to the restricted environment. Individual personality profiles and data on the ontogeny of behavior under these conditions are presented.

No Need To Be Boxed In: Group Pens And Grain For Veal Calves, Michael S. Mosner

Agribusiness Collection

My family has been in the wholesale veal business for 30 years. The basis of this business has been various breeds of female beef calves that are slaughtered at less than 500 lb. These calves are allowed to suck from cows and graze until they are ready for market. Beef calves, however, tend to vary in quality and quantity depending on the tjme of the year that they are purchased and raised. Generally, calves become scarce in the spring, when feeders are buying calves to put out on pasture. Then, in the summer and fall, large numbers of calves usually …

Hsus Veal Campaign Takes Off

Close Up Reports

Through our action packet, which includes a fact sheet describing how veal calves are raised in this country, an action sheet showing what you can do to help, and bright yellow cards to leave when you dine out explaining why you didn't choose veal, you can help get the word out.

It is clear that our efforts to reform milk-fed veal production methods in the U.S. are already producing results. Shortly after our New York Times ad appeared, a large farm group paid to have its own ad published in response. Agricultural trade papers have warned their readers against our …

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, …
