The purpose of this paper was to assess the effect of supplementation of royal jelly on the morphometry of the genital tract, superovulatory response and embryonic quality in adult rabbits. 36 rabbits were distributed in four groups (G), as follows: G1 (n=9): no supplementation with royal jelly, G2, 3 and 4 (n=9): supplementation with 10, 20 and 40mg/day of royal jelly. The superovulatory protocol consisted in the application of a dose of 40UI of Equine Chorionic Gonadotrophin, followed by a dose of UI of Human Chorionic Gonadotrophin, intramuscularly, 48 hours later, and submitted to natural cover. The animals were euthanasiated and the embryos collected 72 hours after copulation. There was no statistical difference for the analyzed variables (P>0.05). The average weight for the female genital tract was 10.89?±0.38g; the average weight of right and left ovaries was 0.28?±0.02g and the average gonadosomatic index rate was 0.02?±0.0g. The number of total recovered structures was 9.2?±1.4. The average number of viable embryos was 8.7?±1.4 and of degenerated embryos was 0.5?±0.2. Viable embryos were morphologically classified as degree I: 5.6?±0.8; degree II: 2.3?±0.5; degree III: 0.8?±0.2. Royal jelly did not present stimulatory effect on organs related to the reproduction of rabbits, nor was it effective to improve their embryonic quality at dosages of up to 40mg of in natura royal jelly.
