Beyond the Bale : September November 2009
September -- November 2009 BEYOND THE BALE The Haemonchus Dipstick Test kit is fully self- contained. It contains all the materials required for on-farm use including instructions, mixing and measuring equipment, an appliance to boil the water in the testing procedure, and the actual Haemonchus Dipsticks. A refill kit will also be available. testing process allows for regular testing of multiple mobs, really allowing for close monitoring of this dangerous parasite. "The sample is mixed with water, heated in a water bath and then cooled. The test- stick is inserted into the solution and then the colours on the stick change according to the amount of haemoglobin in the faecal sample. Simple and quick. "Through the warmer months it could be used up to once a week to predict risks, while in spring and autumn, temperature and rainfall conditions will determine how often it's used." sensitivity of the test it stipulates all the combs and cutters must be scrupulously clean before use," he says. "A 'one sample' kit may be used to collect a single sample from the shearing of a mob of up to 250 sheep. If a mob contains more than 250 sheep, more than one sample should be collected." The NSW DPI team also advises producers not to be tempted to sample only some of the mob. "Sometimes only a few sheep in a mob may be infested," Mr Young says. "Unless all the comb and cutter washings from the shearing of all of the sheep are included, the samples submitted to the laboratory may not contain any lice protein and the test result would be incorrectly interpreted." Test results are available to the woolgrower within three days of the sample being received by the EMAI laboratory. If a sample is positive, woolgrowers are advised to review options for lice control detailed in the Liceboss tool (at www. liceboss.com.au). Woolgrowers can input the details of their situation and the tool will recommend the best course of action. For further information, woolgrowers are advised to consult their animal health adviser or local district veterinarian at their Livestock Health and Pest Authority.

Sheep lice can be the bane of any sheep producer's life. Recent estimates have sheep lice costing the Australian sheep industry over $120 million annually. If left unchecked, sheep lice can cause reductions in wool cut of up to 1 kg per head. They downgrade wool quality by reducing yield and increasing the amount of wool placed in inferior lines because of unscourable colour and cotting. While lice may be considered a fact of life for many, the environ- mental conditions over the last five years have lent themselves to an ever increasing prevalence of lice. After a prolonged period of drought, many producers have opted to forego an annual treat- ment for lice in an effort to reduce costs, particularly if the pres- ence of lice was unknown. Another aspect of drought and the accompanying reduced farm income is that maintenance of farm boundary fencing may have suffered, allowing lice infested strays to join otherwise lice free flocks. In addition to these factors, the large numbers of sheep being traded or going onto agistment has meant that potentially lice infested sheep have been more mobile than ever before over the last few years. Mobile sheep equals mobile lice. It is a sad irony that through managing diminished farm incomes, many producers risk a potential reduction in profitability and in- creased expenses should a lice outbreak be the result. Add to this the fact that there has been a degree of lost confidence in the traditional Insect Growth Regulator (IGR) backliners and the outlook may seem bleak. However, according to Dr Jane Morrison, a veterinary advisor in the Coopers Animal Health lice control division, sheep producers now have access to more products, more solutions and more expert advice to combat lice. Jane has stated that a lice free flock is an achievable outcome. Firstly on the issue of IGRs, Jane asserts that these are still a very effective chemical group on susceptible lice strains, and when used correctly, have a long term place in lice management. Since initiating the Magnum Guarantee in 2007, Coopers have guar- anteed that if any producer uses Magnum and finds lice in their flock 5 months after treatment, having followed a standard lice management plan, Coopers will send an expert to their property to assess the problem. The Coopers representative will provide advice for a lice management program tailored to the property and where necessary assist in solving the lice problem using an- other product from within the Coopers lice control range. "For producers with lice issues or those wishing to prevent an is- sue, the first and most important step", says Jane, "is to formulate a Lice Control Management program for their property; this will take into account all aspects of your farm management from fencing to shearing. With a management plan they can then progress to selecting the most appropriate lice control products their property and ensure that they are applied correctly". "The best way in my mind" says Jane "to achieve lice control is to contact your local Coopers Lice Advisor. They will work through everything from top to bottom so that the end result will be a lice free property". Now is the ideal time to contact your local lice control expert and see what not controlling your lice could be costing you. Coopers lice control experts are available for a free lice control consultation and you can contact your local advisor by calling 1800 885 576.
