Abstract :In this study, it was investigated that the effects of phase feeding diets containing different levels of phosphorus on the performance and some bone characteristics of broiler chicks different periods of growth cycle. Ross-PM3 chicks used in this experiment were separated into four groups. The first group was fed with ration containing 0.45% available phosphorus insert ignore into journalissuearticles values(AP); during all period of experiment. The second and third groups were fed with 0.45% AP for the first two weeks and later, 0.35% and 0.25% AP at end of experiment, respectively. The fourth group was fed with 0.45% AP for the first two weeks, 0.35% AP for the next two weeks and 0.25% AP for the last two weeks. The body weights of birds at 25 and 35 days and live weight gains at 14-21 days period were affected significant-ly insert ignore into journalissuearticles values(P<0.05); by ration P level. The body weight and live weight gains of the groups fed with the ration containing 0.45% AP was significantly P<0.05); higher than other groups. Ration P level did not affect significantly feed consumption, feed conversion ratio, bone strength, percentage of bone ash of in all groups.
