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 breeding vertebrates during normally non-reproductive seasons by administering L-dihydroxyphenylalanine (L-DOPA), thereby increasing the level of L-DOPA in the vertebrate's bloodstream to a reproductively active level. An effective amount of 5-HTP can also be injected into the vertebrate followed, an effective period of time later, with an injection of an effective amount of L-DOPA.
