Abstract:Cyclic and pseudopregnant rats were treated with ergocornine hydrogenmaleate (1 mg), to evaluate the use of induced luteolysis as a method for synchronizing mating. Pseudopregnancy in non-treated rats was found to decrease the degree of mating synchronization, prolong gestation and decrease the number of young born per pregnant female. Ergocornine treatment of both cyclic and pseudopregnant rats decreased pregnancy rate. Ergocornine treatment of pseudopregnant rats also increased the degree of synchronization … Show more
