  • Title: Effect of time of day of insemination and the position of the egg in the oviduct on the fertility of turkeys.
    Author: Christensen VL, Johnston NP.
    Journal: Poult Sci; 1977 Mar; 56(2):458-62. PubMed ID: 605033.
    Abstract:
    Turkeys were inseminated at six different times of the day (1:00 p.m., 3:00 p.m., 5:00 p.m., 6:00 p.m., 9:00 p.m., and 12:00 a.m.) to determine the effect of time of day of insemination and the stage of egg formation on fertility. Significantly (P less than .01) lower fertility resulted from insemination at 1:00 p.m. than from inseminations thereafter. Significantly higher fertility resulted from 9:00 p.m. and 12:00 a.m. insemination than from preceding times. Highest fertility resulted when inseminations were performed 8 to 18 hours prior to oviposition whereas lowest fertility resulted from hens inseminated both in the last seven hours of shell deposition and during the approximate time of ovulation.
