Reproduction

Introduction to out of season breeding and synchronizing heats in small ruminants

Using the EAZI-Breed CIDR-G for Out-of-Season Breeding in Ewes (PDF) by Dr. Keith Inskeep - This document provides the basis for using progesterone CIDRs (controlled internal drug releasing devices) to synchronize estrus or to start the reproductive cycles of ewes that may not be cycling during spring, when daylength is increasing.

Reproductive results from breeding our milking ewes in March-April and June have been dramatically better than those reported in this paper. That may be due to the exposure of the ewes to vasectomized rams about 10 days prior to the insertion of CIDRs.
