Abstract :In current study, the effects of four different cabinet temperatures for last four days of incubation in broiler hatch-ing eggs on post hatch performance for 3 weeks of age and Ca and P mineral levels in toe ash were evaluated. In this respect, the cabinet temperatures were kept as 97, 99, 101 and 103 0F and termed as D, KON, Y, and ÇY, respectively, for last four days of incubation. The current results shows that the heart weight increased significantly insert ignore into journalissuearticles values(P<0.01); in D treatment group than did others at hatch. Moreover, the gizzard weights were lower insert ignore into journalissuearticles values(P<0.01); in Y and ÇY groups than did others at hatch too. On the contrary, the hearth, liver, gizzard weights were not different. The total mortality rates in D, Y and ÇY groups have exhibited higher values insert ignore into journalissuearticles values(P<0.05); than KON group. The toe ash Ca levels increased signif-icantly insert ignore into journalissuearticles values(P<0.01); in Y group than did others, while treatment effects on P levels were not significant. There were found no differences among groups for post hatch performance traits.
