|Racewell Sheep Handler or Auto Drafter:
|Adult equivalent rating - lambs
|Adult equivalent rating - ewes - twinners

|How many lambs are weaned per ewe
|How many ewes are required if my weaning rate is aligned to the benchmark / (lambs weaned divided by weaning %)
|How many additional ewes are you carrying?
|What is surplus value of the additional ewes I am carrying
WHAT IF SCENARIOS
What would it look like if you substituted all the under-performing ewes for half as many fecundant ewes.
|Less the under-performing
|Plus half as many better performing
|The number of performing ewes is now
|Lambs weaned (using the benchmark weaning percentage)

Dry Sheep Equivalent (DSE)
DSE is a standard unit frequently used in Australia to compare the feed requirements of different classes of stock or to assess the carrying capacity and potential productivity of a given farm or area of grazing land.
The unit represents the amount of feed required by a two-year-old, 45 kg Merino sheep (wether or non-lactating, non-pregnant ewe) to maintain its weight. One DSE is equivalent to 7.60 megajoule (MJ) per day.
