Broiler chicken sudden death syndrome

Question for written answer E-004980-15
to the Commission
Rule 130
Daniel Buda (PPE)

Broiler chicken sudden death syndrome occurs in the first month of life and has an asymptomatic evolution, ending in unexpected death. One of the factors is represented by the biotin-deficient feed rations, which determine a deficit of arachidonic acid. The low levels of arachidonic acid cause changes of heartbeat and of the heart’s contractility. Wheat‐ and soy-based feed, as well as high-protein feed favour this syndrome.

Mortality may also be due to hepatorenal syndrome, as biochemical tests often reveal an increase of the level of lactic acid in the blood. The experiment consisting in the ingluvial administration of a 20% solution of lactic acid to 2 to 4-week old chickens causes similar symptoms to those of sudden death syndrome.

What is the Commission’s position concerning the continued use of feed that causes the death of broiler chickens?

What measures can the Commission take in order to decrease the incidence of this syndrome?
