Beyond the Bale : Oct 07 - Nov 07
15 FLOCK MANAGEMENT BEYOND THE BALE Lifetime Wool resources for woolgrowers A host of information about Lifetime Wool, including ewe management guidelines, tools and tips, and background research results with economic analysis, is available on the Lifetime Wool website (www.lifetimewool.com.au). In addition, the following hard copy resources are available from the AWI Helpline, 1800 070 099: ú Ewe Management Handbook -- optimising Merino ewe nutrition to increase farm profit; ú Feed Budget Tables -- for drought/dry conditions in southern Australia; and ú Feed Budget Tables -- for green pastures in south-eastern Australia. "For example, on our property we've not gone the whole way with nutrition and monitoring. We want to decrease the amount of weight our ewes lose, but we don't undertake a lot of condition scoring, although producers still need to monitor sheep so they know what losing 0.5 CS feels like." He is also keeping sheep off the pasture paddocks until two to three weeks after rain -- a pasture deferment strategy identified in the economic analyses. "We used to leave the sheep on the pastures and they'd slowly get more pastures in front of them. Now we keep them off the paddocks until they reach 800 to 1000 kilograms a hectare of pasture. We normally get a break late April or May, and we defer them until the end of May or into June." Mr Young says Lifetime Wool's principles are the logical next step for producers wanting to make the most of their enterprise, and they show producers where they should be aiming. "But producers should understand Lifetime Wool's biological findings first and then look at the economics of it all." The project quantifies what many producers were already doing, he says. "It just puts some figures on it. This will help us do it better, or give us the confidence to say we have untapped potential up our sleeve."

However, by following the optimum profile (below), profit could increase by as much as $30,000 on a 1000ha enterprise. Profile 1. Profit is lower due to higher supplementary feeding costs in autumn Profile 2. Optimum due to lower feeding in early pregnancy and regaining condition on green feed Profile 3. Profit is lower due to impacts from lower condition at lambing Profile 4. Ewe and lamb mor tality severely limits profitability Figure 2 Optimum profile for the medium- rainfall zone (WA's Great Southern region) If ewes are allowed to lose condition over autumn and only maintain it after day 90 (rather than regaining condition), there will be a reduction in profit of at least $3.00/ewe, compared with the optimum profile, which could increase profit by as much as $40,000 on a 1000ha enterprise. Profile 1. Profit is lower due to higher supplementary feeding costs Profile 2. Optimum due to lower feeding in early pregnancy and regaining condition on green feed Profile 3.
