Use of the EAZI-BREED Sheep CIDR in Spring Mated Ewes

Efforts to manage the reproductive cycle of the ewe have been a focus of producers and researchers for decades.

Recently a commercial progesterone intra-vaginal device, the EAZI-BREED sheep CIDR (controlled internal drug release) was approved in the US to synchronize estrus in mature ewes during the anestrous period.
