“…In vivo donkey embryo production after natural mating or artificial insemination has been reported previously with an embryo recovery rate per cycle from 50% to 76% [8,9]. In equids, embryo production in vivo is limited because experimental induction of multiple ovulations has a low efficiency [10] and routine induction of multiple ovulations is still ineffective [6].…”

The Martina Franca (MF) donkey breed, with 48 jackasses and 515 jennies, is considered an endangered breed according to the data from the Monitoring Institute for Rare Breeds and Seeds in Europe. The knowledge of the estrous cycle characteristics has a great impact for assisted reproduction, especially in endangered species. In this study, the estrous cycle characteristics were investigated in 12 MF jennies throughout the year. Estrous cycle, estrous and diestrous lengths, follicular growth and ovulation, and estradiol-17β (E2) and progesterone (P4) plasma concentrations were monitored in MF jennies and compared in different seasons. In all jennies (100%) estrous cycle was detected during the whole year, with no differences in the estrous cycle length among seasons. However, a significant increase of estrous length in spring and summer compared with autumn and winter was found. Diestrus was shorter in summer than in the other seasons. Estrous behavior was always shown and characterized by rhythmic eversion of the vulvar labia (winking) with exhibition of the clitoris, urination, male receptivity and clapping, with sialorrhoea, neck and head extension, and back ears. Estrus was characterized by the ovulation of a larger follicle in spring and summer than in autumn and winter. The pattern of E2 and P4 plasma concentrations during the estrous cycle were similar to that reported for the mare, but without differences among the four seasons, so that a negligible effect of environmental conditions on ovarian E2 and P4 secretion was hypothesized, despite the larger diameter of the ovulating follicle in spring and summer.

“…No studies reporting the in vitro assessment of cryopreserved donkey embryos were found in the literature. To the authors' knowledge, Panzani et al [21] describe the use of DAPI staining only in fresh donkey embryos. They observed a low number of dead cells in fresh donkey embryos, which was not correlated with embryo size.…”

Vitrified horse and donkey embryos did not show higher susceptibility to cell damage than those preserved by slow freezing, whether using straws or Fibreplug. However, Fibreplug with EG 7 mol/L resulted in fewer nonviable and apoptotic cells in donkey embryos. Donkey embryos showed lower susceptibility to vitrification than horse embryos.
