Two experiments are described in which deep-frozen ram semen was
used for artificial breeding. In Trial 1, natural mating and A.I. with
fresh semen or frozen semen were compared at first and second cycles
after synchronization of oestrus. Overall conception at second cycle was
higher than at first cycle. But the results from frozen semen were much
lower than the other methods of mating at both cycles. In Trial 2, A.I.
was done with fresh or frozen semen at two sites (cervix or uterus).
Fresh semen gave higher conception than frozen semen and uterine
insemination was superior to cervical insemination.
