Use of hCG, eCG or p-FSH on estrus induction of goats and their effects on luteal dynamics and conception rate.

Use of hCG, eCG or p-FSH on estrus induction of goats and their effects on luteal dynamics and conception rate.

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.
