Perches as Cooling Devices for Reducing Heat Stress in Caged Laying Hens: A Review

Jiaying Hu, Yijie Xiong, Richard S. Gates, Heng-Wei Cheng

Published in 2021

Scientific review presenting the results of a multi-year study on the capacity of perches containing a cooling circuit to reduce heat stress in laying hens. It demonstrates the effectiveness of this cooling system when combined with an enrichment element in reducing body heat and heat stress in laying hens.

L’agriculture bio garantit-elle un meilleur « bien-être » des animaux d’élevage ?

Eugénie Duval, Benjamin Lecorps

Published in 2021

Article demonstrating that the French organic label guarantees higher animal welfare standards than conventional farming, providing access to outdoors, banning cage rearing and tethered systems, allowing only exceptional authorisation of non-medical surgical interventions, and requiring more frequent checks and compulsory stunning before slaughter. However, the legislation on transport and slaughter is still inadequate, even in the case of organic farming.

Animal welfare: a shift from live to meat-and-carcass transport

Gediminas Vilkas

Published in 2021

Press release presenting the results of the European Parliament's Committee of Inquiry into the protection of animals during transport. The committee recognised that EU rules on the protection of animals during transport are not always respected and that the welfare needs of animals during transport are not always met. It recommends limiting and better monitoring the export of live animals, developing meat-and-carcass transport and banning the transport of very young animals.

Global Animal Partnership Releases Initial List of Eligible Broiler Breeds for Animal Welfare Certification

Robin Chwatko

Published in 2021

News item presenting the results of scientific work commissioned by the Global Animal Partnership to understand and measure the welfare levels of broiler chickens. This work has resulted in a list of breeds that have high genetic welfare levels and are therefore recommended for welfare-friendly breeding.

Centennial Review: A revisiting of hen welfare and egg safety consequences of mandatory outdoor access for organic egg production

Peter S. Holt

Published in 2021

A scientific review comparing the welfare of laying hens and the sanitary quality of their eggs in free-range and indoor systems. It concludes that diseases are more frequent and severe and that there is a greater risk of Salmonella infections and the contamination of eggs by toxic industrial by-products in hens with access to the outdoors.
