[The use of follicle-stimulating hormone (FSH-P) for the induction of superovulation in cattle].
The clinical effectiveness of FSH-P for initiating superovulation in cattle was examined in 948 animals of the breed Deutsche Schwarzbunte and Deutsche Rotbunte of RPN Verden during 1988 and 1989. In the group of the FSH-P treated animals the number of transferable embryos was 4.4 +/- 4 per animal. The 25% percentile was 1 and the 75% percentile was 7 transferable embryos per donor. In 88 animals no embryos were found. In animals with a large number of embryos there was a changed quotient between transferable embryos and non transferable embryos per animal. A seasonal dependence in the number of transferable embryos was not found. Repeated treatment with FSH-P seemed to have no influence on the number of transferable embryos per animal. In the dose range between 6.6-9.4 mg FSH-P no differences in the number of transferable embryos per animal were found.
