Beyond the Bale : September 2018
ON FARM 61 ELMORE FIELD DAYS MERINO DAM PROVES ITS WORTH EXTENDING THESE RESULTS While the trial generated valuable information about the wool and meat income per head for each ewe type, this did not provide gross margins per DSE or per hectare. Further analysis of the Elmore Field Days trial was conducted using GrassGro to generate this gross margin information and extend the results across three distinct market scenarios experienced during the 24 years between 1994 and 2018. The market scenarios considered were: • 1994-95 to 2001-02 which was characterised by low lamb prices • 2002-03 to 2009-10 which was a period of drought • 2010-11 to 2017-18 being recent years with more contemporary prices. GrassGro is a computer simulation program that draws upon decades of field experimentation from across Australia to model interacting processes of pasture growth and animal production. Livestock details for the five ewe enterprises considered in the Elmore Field Days trial were inputted into GrassGro along with management scenarios, costs and prices, to generate gross margins for the three distinct market environments experienced between 1994 and 2018. The results show that the Merino dams (Centre Plus and Loddon Valley Merinos), followed by Dohnes, had the highest gross margins per hectare across the all market conditions when ewes were stocked at the same DSE per hectare. This project was funded and conducted by the Elmore Field Days Inc together with The Campaspe Prime Lamb Producers Group with professional help from three organisations and six product support sponsors. AWI provided funds for statistical and economic analyses.
