| Abstract: The in vivo production of embryos is used to accelerate the multiplication of the herds, but the efficiency of this biotechnology is widely variable in small ruminants. The variability of the superovulatory responses and the production of viable embryos has been related to several factors, including the dose of gonadotrophin used in the hormonal treatment of superovulation, and the occurrence of prematurely regressing corpora lutea. In this context, the present study was performed to evaluate the effect of different doses of pFSH on the superovulatory response and vascularization percentage of the corpora lutea (CLs) formed. In conclusion, the vascularization percentage of the corpora lutea during the initial luteal phase is affected by the dose... |

| The current paper characterizes the changes in morphology and vascularization of the corpus luteum of collared peccaries during the estrous cycle and correlates progesterone synthesis (P4). Twenty females were subjected to a treatment for estrus synchronization; an ear implant containing 1.5 mg of norgestomet was implanted on D0, whereas on D9 the peccaries received an IM injection of eCG 200UI and 50g of PGF2a. The animals were divided into four groups (G1, G2, G3 and G4) and euthanized on postovulation days 3, 12, 18 and 22. The ovaries were collected and the corpora lutea were measured and processed for histological and vascular density (Dv). Blood was collected for dosage of P4 serum. The morphology of the ovaries, the corpora lutea and P4 varied... |

| The present study tested the hypothesis that hCG and pFSH stimulate the follicular development and consequently corpora lutea, in a manner equivalent to those induced by eCG in goat. Eighty-five Toggenburg goats, during the seasonal transition period (December, 21ºS), underwent a short-duration estrus induction/synchronization protocol with a sponge impregnated with medroxyprogesterone acetate (60 mg MAP, 6 days). In conclusion, the use of hCG and pFSH in protocol of estrus induction/synchronization in goats induces equivalent luteal dynamics and conception rate, being substitutes for eCG. |
