Effect of egg position in storeroom and hatchery on hatchability traits of turkey

This research was conducted to investigate effect of turkey egg position in storeroom, prior to hatching, and egg position in hatchery on fertility and hatching traits of eggs. The statistical method was 2×2 factorial arrangement in randomized complete block design. In this research, eggs from one breeding house of turkey research station of Iran (Tatar station) were divided daily into four groups for four mounts. Then the eggs disinfected and stored in two positions, small end up and small end down, in storeroom at 15-18 degrees centigrade and 50-60 % humidity. In seventh day, all of weekly produced eggs were transferred to incubator separately and simultaneously. In the last three days of hatching, in the time of transferring to hatchery, similar treatments were put in two horizontal and vertical positions in hatchery. The results showed that fertility and hatchability was differed significantly for month of egg production as block (P0.05). Egg position as small end down in the late three days improved eggs hatchability and decreased losses (P>0.05). Interaction of small end up eggs position in storeroom and small end down eggs position on hatchery increased eggs hatchability up to 7.2 % (P
