Welfare of broiler chickens [PDF]

Italian Journal of Animal Science, 2009
Broiler chickens have been selected for their rapid growth rate as well as for high carcass yields, with particular regard to the breast, and reared in intensive systems at high stocking density ranging from 30 to 40 kg live weight/m2. These conditions lead to a worsening of the welfare status of birds. In Europe a specific directive for the protection
