Every fall I borrow a Katahdin ram from a fellow sheep raiser after he has bred his ewes. In late January I heard from him with the news no one wants to hear – the ram was sterile and he had no lambs this year. I wasn’t due to start lambing until March 5th and while I “thought” some of the ewes looked pregnant it was too early to tell for sure so I started my usual month before lambing feeding regimen. The fifth of March came and went with no lambs. I had never before had a lambing season where I had not had at least one ewe lamb on the first day I could expect lambs; i.e., 150 days from the day the ram was introduced. By March 12th, while it appeared several ewes were indeed pregnant, I still had no lambs so I went back to my usual feeding schedule.
April 8th will be the last day I can expect lambs. April is just a couple of days away so it is still unknown whether the ram was indeed sterile or whether some of my ewes are indeed pregnant.
She is starting to bag up.
