title: [Use of radio-immuno-assay of gonadotropic hormones in farm animals (author's transl)].
abstract: The determination of the concentration of gonadotropic hormones in the peripheral plasma of farm animals by radio-immuno-assay is described. Particular attention was paid to the determination of ovine, bovine and porcine LH using an anti-ovine-LH serum. This serum was found to be specific for LH, and there was no cross-reaction with FSH. Cross-reactions with TSH cannot be ruled out. The usefulness of this antiserum was tested in studying the release of LH during oestrus (in sheep), after injection of LH-RH (in cattle and pigs) and after weaning (in pigs). The results are in accordance with those reported in the literature.
