Reproduction Management

Ceva is recognized as an expert in the field of small ruminants reproduction.

A Ceva Sante Animale field of expertise

Ceva is recognized as an expert in the field of small ruminants reproduction. Innovation has been the driver for Ceva when developing products for small ruminant veterinarians and producers. As experts in progesterone intravaginal devices, Ceva developed the Syncropart® sponges for reproduction management in sheep and goats. The Syncropart® protocols includes also Syncropart® PMSG. The use of melatonin (Melovine®/Regulin®) as a reproductive tool was one of the latest contributions of Ceva in this field.

Ceva has collaborated over the years with scientists and veterinary practitioners in increasing the knowledge in the field of sheep and goat reproduction. This has resulted in the publication of scientific papers in different journals. Regularly the company has been involved in educational programs that have contributed to expand that knowledge among small ruminant veterinarians. As part of those activities Ceva launched the website The website gathers together all the data and publications available to the public and professionals on the subject of control of reproduction in cattle, sheep and goats.

  • MELOVINE® / REGULIN®  (melatonin implant).

Ewes have a seasonal reproduction rhythm that depends on the length of daylight. Sexual activity manifests itself, depending on the breed, as the days get shorter (autumn). MELOVINE®  is an implant that releases melatonin (a natural substance secreted by the brain during the night) progressively and at sufficiently high plasma concentrations for a period of 70 to 90 days to simulate the shortening of the days. The implant is positioned at the base of the ear and does not need to be removed as it is biodegradable). In ewes, it induces œstrus and ovarian activity 50 to 70 days after it is implanted. In rams the use of the implant increases sexual activity during the anoestrus season and it increases the quality and quantity of the sperm.


SYNCRO-PART® sponges  contain 30 to 45mg of fluorogestone, depending on the species and age of the females (gimmers, ewes, goats). After the insertion of the sponge, the fluorogestone released mimics the action of natural progesterone and blocks the sexual cycle. When the sponge is removed, the drop in serum fluorogestone levels triggers œstrus. The SYNCRO-PART® sponge   associated with SYNCRO-PART® PMSG   provides a comprehensive method to induce and synchronise heat in the sexual season or out of season. This opens up the possibility of bringing the service period of small ruminants forward and grouping the arrival of the lambs.
