Extract

1. Eight Cheviot ewes, bearing twins, housed in individual pens, and given the choice of a protein concentrate, a carbohydrate concentrate, hay, minerals and water, failed to select a ration that allowed them to bear and rear strong healthy lambs.

2. Three ewes maintained under these conditions developed a condition resembling pregnancy toxaemia.

3. The amount of food eaten by each ewe decreased during the last few weeks of pregnancy, This is probably the reason for the disappointing performance of the ewes at lambing.

4. The possible influence on the behaviour of the ewes of the constant presence of food is discussed.
