[Vaginal cytology studies on the determination of the onset of estrus cycle post partum in sheep].
State of vaginal cells and arborisation grade of cervical mucus were studied in 364 Merino ewes of meat type from the 7. day ante partum. The Pundel modified Shorr-straining method and the Papanicolaou-straining method were used for differentiation of the cells (casal-, parabasal-, intermediate-and superficialcells). Near the 44., 54. and 70. day post partum a maximum of superficialcells and simultaneously a high grade of cervical mucus arborisation in elongating cyclic intervals can be observed in lactating ewes. In conclusion an early weaning of lambs between the 40. and 50. day post partum is considered to be in aggreement with cyclus.
