We have been interested in developing Polyestrous traits into our Nudie flock so they have the ability to lamb out of season and also successfully re mate with the ram during lactation.
Each November we run rams with the ewes while they have 10 week old lambs at foot and are finding a few that lamb the following April.
Spring 2017 will see Polyestrous rams back into the flock and we are curious to see how long this trait takes to spread.
On of the best ewes born in 2010, 104059 has had a set of twins every year since and two sets of twins in 2016.
