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 …

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 …

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 …

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 …
