Data from one farm in
Florida that included contemporaneously transferred
vitrified embryos are presented in Table 4. Although not
significantly different (P > 0.1), transfer of vitrified embryos
resulted in numerically lower pregnancy rates than transfer
of fresh embryos or TAI.
There was no significant difference in pregnancy loss
between initial pregnancy diagnosis and term between
treatments (Table 3). The percentage of calves that were
female was higher (P < 0.05) for the TET group receiving
embryos produced with X-sorted sperm than for other
groups in which nonsorted semen was used (Table 3).
