Fast-growing breeds have long been criticised by animal welfare groups because their rapid growth can cause severe health and mobility problems. Norway will become the first country to eliminate fast-growing chicken breeds entirely under the industry transition.

The decision affects a sector producing around 70 million chickens for meat each year, and around 60 percent of chickens currently raised in Norway are fast-growing breeds. Animal welfare campaign group Anima International spent five years campaigning for the transition. The decision has intensified pressure on poultry producers and retailers in other countries to adopt similar welfare standards.
