Caprine reproductive system; cumulus-enclosed germinal vesicle oocytes aspirate from antral follicles for embryo production; (#) the place in fallopian tube where the 1-8 cell-stage developed embryos are collected or transferred; (*) the place in the uterine tube where the morula-blastocyst embryos are collected or transferred (Mohammed and Kassab, 2015).

Figure 4:

Rabbit offspring obtained after transferred embryos to uterus of surrogate mothers (Mohammed et al., 2011).

Figure 5:
