Splitting off dry ewes. Their feed requirements are approximately 50% less than those of single-bearing ewes. These ewes could be run as wethers. Selling off dry ewes or rejoining the empty ewes later. Identification of ram performance 35 days post joining. Early detection of infertile rams enables remedial action to be taken. Separation of early and late-lambers to enable differential feeding and ease of management during lambing. Maximisation of wool production from ewes and progeny by maintaining adequate feed: If the nutritional requirements of pregnant ewes are not met these ewes produce less wool and more tender wool. The progeny are smaller in body size producing less wool that has a high fibre diameter, greater variation and lower tensile strength. Under-nutrition from day 90 of pregnancy will reduce the number/density of secondary follicles formed in the skin of developing lambs by up to 30%. Improving survival rate of twins through differential feeding. In the last trimester of pregnancy twin-bearing ewes require approximately 20% more feed that single-bearing ewes.

WHEN TO SCAN? Wet / dry pregnancy testing of ewes can be determined from 35 days after the ram has been removed (however the optimum time for pregnancy testing is between 40 and 100 days).
