PROCESS FOR ACTIVATING REPRODUCTION OF SEASONAL BREEDING ANIMALS BY ADMINISTERING L-DIHYDROXYPHENYLALANINE (L-DOPA)

摘要

A process is provided for activating reproduction in seasonal breedingvertebrates during normally non-reproductive sea-sons by administering L-dihydroxyphenylalanine (L-DOPA), thereby increasingthe level of L-DOPA in the vertebrate's blood-stream to a reproductively active level. An effective amount of 5-HTP can alsobe injected into the vertebrate followed, an effec-tive period of time later, with an injection of an effective amount of L-DOPA.
