Frequency of Spontaneous Fragmentation of Ova In Unbred Gilts

Abstract

Unfertilized ova were recovered from the reproductive tracts of 31 gilts, 2-10 days after estrus. Examination of the ova revealed that 80% of ova recovered from uterine horns were fragmented. The proportion of fragmented ova increased directly with post-ovulatory age of the ova.
