Analysis of lambing records show loss increases after the first cycle for ewes have lambed. Later lambing ewes have higher mortality as diseases build and lambing staff get tired. Keep the lambing period short by using teasers followed by tups that have had an MOT. This involves simple checks to ram health involving looking for head and brisket sores, checking feet and genital. You can be trained to do this or use a vet specialising in sheep work.
Using rams that produce viable sperm from the start of mating and are fit to cover many ewes per day should ensure around 85% are in lamb to the first cycle.
