With nearly 370 billion animals confined behind bars each year, battery farming remained, in 2017, widely acclaimed by European breeders. Described by animal defense associations for decades, cages, which, it should be remembered, do not meet the physiological needs of rabbits, ducks, quails and other pregnant sows, but are no longer popular.

In addition to surveys, which regularly show consumer opposition to these farming methods, several European countries have for example banned certain battery production methods. This is the case of Luxembourg, Austria and Germany which banned the raising of laying hens in battery from 2020 and 2025 in the wake of the big retailers - but not France; or Sweden and the United Kingdom which ended the gestation cages - or even parturition - for sows.
