Pre joining strategies

With the large number of wet days, we have had to delay the weaning of our lambs. This has had two effects, the ram lambs are close to being sexually active and need isolating. But of more immediate importance is the ewes are down in condition, and joining is rapidly approaching.
What we must do now is  to "flush" the ewes, this means they need a rapid rise in nutrition, ideally with a boost in protein intake. Even in normal circumstances this will give an increase in the number of twins.
