DSE ratings for different stock types update automatically. For cows this could be based around when bulls go in and out and weaning date. Using these markers, autmatic DSE ratings can change automatically as the cow moves through its gestation period into lactating where it has higher demand.
Dry stock could be set to a average daily weight gain or various weight gains depending on the pasture/crop they are on and the season. When a daily weight gain is assigned, the DSE rating of the animal can be updated automatically. IF stock are weighted, mob average weight can be adjusted to real weight and DSE realigns.
Having a better understanding of how many DSE each paddock has carried will provide better data on paddock performance and allow better, more accurate management decisions.
