The prestarter feed includes selected ingredients with antioxidant and anti-inflammatory properties and has been designed for piglets having high levels of oxidative stress. Oxidative stress, often occurring during weaning, induces immunodepression, in which defense capabilities of the body are exceeded by the production of ‘free radicals’. These unstable molecules coming from the redox process enhance cell damage and induce a decrease of animal health. Inflammatory stress is often induced by this process, leading to growth retardation growth. Generally, this type of stress disappears rapidly five to six days after weaning, but in sick animals, it continues.
