Comparative effects of furnished and battery cages on egg production and physiological parameters in White Leghorn hens.
Laboratory animal well-being can be improved by housing the animals in species-specific natural or near-to-natural environments. An enriched environment may have a similar effect on chickens. The purpose of this study was to examine if housing environment (furnished cages vs. battery cages) effects the well-being of laying hens. One hundred ninety-two 1-d-old non-beak-trimmed White Leghorn W-36...
متن کاملAn HSUS Report: A Comparison of the Welfare of Hens in Battery Cages and Alternative Systems
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 cm 2 (67 in 2 ) of space per bird. Cages prevent hens from performing the bulk...
متن کاملThe long-term productivity of hens housed in battery cages and an aviary.
This study examined the long-term effects of housing system on several aspects of laying hen production. At 19 wks of age, 336 White Leghorn hens were placed, 3 birds per cage, into battery cages; 437 birds were assigned to an aviary with communal nests, ambulation areas, and three raised tiers with feeders and drinkers. Family groups were split between the two housing systems. The hens were ho...
متن کاملFurnished cage system and hen well-being: Comparative effects of furnished cages and battery cages on behavioral exhibitions in White Leghorn chickens.
The battery cage system is being banned in the European Union before or by 2012, and the furnished cage system will be the only cage system allowed after 2012. This study was conducted to examine the different effects of caging systems, furnished cages vs. battery cages, on bird behaviors. One hundred ninety-two 1-d-old non-beak-trimmed Hy-Line W-36 White Leghorn chicks were reared using standa...
