EFFECT OF ALTERNATING LIGHTS AND STRAIN ON ROASTER CHICKEN PERFORMANCE AND MORTALITY DUE TO SUDDEN DEATH SYNDROME

Abstract
Treatments in which light alternated from side to side within pens at regular intervals had no effect on male roaster chicken performance or mortality due to sudden death syndrome (SDS) compared with continuous light. Strain differences in performance and SDS mortality were noted. No differences were found between the locations of death of chickens dying from SDS vs. other causes. Key words: Alternating light, roaster chicken performance, sudden death syndrome
