The United States Food & Drug Administration has approved EAZI-Breed CIDR Sheep Insert (progesterone solid matrix) for induction of estrus in ewes during seasonal anestrus.
This progesterone controlled intravaginal drug release (CIDR) is a steroid hormone that allows out-of-season breeding in sheep, FDA said.
The data to support this approval were gathered in collaboration with the National Research Support Project–7 (NRSP-7), a US Department of Agriculture program intended to support the approval of new animal drugs for minor species of agricultural importance.
"Members of the US sheep industry have long cited this type of product as their top priority need," said Dr Meg Oeller, director of the Office of Minor Use & Minor Species Animal Drug Development within the Center for Veterinary Medicine.
"Through efforts with our partners at NSRP-7 and the pharmaceutical firm, FDA can now point to an approved drug product that is fulfilling a real need in the sheep industry. It represents the true spirit of the MUMS Act."
EAZI-Breed CIDR Sheep Insert is manufactured by Pharmacia & Upjohn, a division of Pfizer Inc., New York.
