Determination of Dorper DSE rating for stocking decisions

Summary

​The Dry Sheep Equivalent (DSE) is a standard unit used to compare the feed requirements of different classes of livestock or to assess the carrying capacity and potential productivity of a given paddock. Field Metabolic Rates and Water Turnover Rates of Dorper sheep were assessed under the semi-arid condition of western NSW to establish their DSE rating. Results showed no significant difference between Dorpers and Merinos in either Field Metabolic Rate or Water Turnover Rate. However there was significant difference in Body Water Content of the two breeds. It is concluded that DSE rating of individual animal cannot be criterion to determine the safe stocking rate of Dorper sheep.
