SUSTAINED-RELEASE AGENT FOR SUPEROVULATION TREATMENT, SUPEROVULATION TREATMENT SOLUTION, SUPEROVULATION TREATMENT SET, SUPEROVULATION TREATMENT METHOD, FERTILIZED EGG PRODUCTION METHOD, AND USE OF PROTEOGLYCAN AS SUSTAINED-RELEASE AGENT
To provide technologies that can carry out superovulation treatment of domestic animals, such as cattle, using natural products without causing induration, more easily than conventional methods.SOLUTION: A sustained-release agent 10 for superovulation treatment is a sustained-release agent for imparting sustained release to a follicle-stimulating hormone agent (FSH), and is composed to contain a proteoglycan 2 in a solvent 3. The content of the proteoglycan 2 is set to be 20 mg per 1 ml or more. For the solvent 3, use of physiological saline is sufficient. Particularly the sustained-release agent 10 can be suitably used for the fertilized egg production of livestock.SELECTED DRAWING: Figure 1
