McNay Research and Demonstration Farm
The McNay sheep research flock was established in 1989 when the flock was relocated from the Beaconsfield research farm. Currently, the flock is composed of 200 white-faced, prolific crossbred ewes. Past work has demonstrated the management needed for an intensive lambing schedule with commercial flocks in Iowa. This flock accomplished over 70% accelerated lambing. One area of research that dramatically improved spring conception rates was light priming of the rams during the four months prior to breeding.
