Royal Jelly May be Effective in Improving Ewes’ Pregnancy Rates

Reproductive Responses in Ewes Treated with eCG or Increasing Doses of Royal Jelly
Animal Reproduction Science, Volume 92, Issues 1-2 , March 2006, Pages 75-85

Abstract: This experiment was conducted to evaluate the effect of administering increasing doses of royal jelly (RJ) on reproductive parameters in ewes. Additionally, this study compared using RJ vs. equine chorionic gonadotropin (eCG) in estrous cycle control. . .Lambing rate was higher (P < 0.05) in the RJ500 group compared with controls. . .

Results of the present study demonstrate that eCG but not RJ was effective in improving estrus expression in ewes during the transition between the non-breeding and breeding seasons. Royal jelly may be effective in improving pregnancy and lambing rates but further studies are required to confirm such findings.
