Abstract
Three commercial layer strains were used in this experiment they were Hy – Line W36 (White colour), Shaver 579 (Brown colour) and Bovains Goldline (Brown colour) to evaluate the effect of there interaction with anti – cannibolism method (plastic anti – cannibalism (glasses) and debeaking) and types of protein (concentrate and premix) on some productive characteristics (egg production, egg weight, feed consumption and feed conversion ratio) through four periods of age (25 – 28, 29 – 32, 33 – 36 and 37 – 40 weeks). The results which obtained from this study were as followed: - 1- The interaction between Hy – Line W36, glasses and protein concentrate or premix recorded significant domination at other interactions in all productive characterstics except egg weight. 2- High egg weight showed in the interaction between Shaver 579 (Brown strain), beak trimmed, protein concentrate or premix supplementation to diet as a comparison with other interaction.
