Beyond the Bale : Aug - Sep 08
11 Road to 2010 BeYond The Bale researCh demonsTraTes ThaT Clips work a study evaluating the performance of clips against mulesing is proving that the clips are an effective alternative. data from six trials that commenced last spring, on properties in South australia, Victoria and New South Wales, have been statistically analysed. at each location, a mob of 360 lambs were either clipped, mulesed or left untreated (non-mulesed). the trial will go for 24 months, but the results so far (up to day 90) have been analysed and show the advantages of mulesed sheep and the advantages of clipped sheep. aWI project manager for blowfly control Ian Evans says more data will come as the two-year study progresses to day 180, then day 360 and day 700. “the 90-day results from the ‘positive control’ clip study are a very significant outcome for industry,” he says. “they confirm clip experiences to date, quantify their benefits and highlight where continuing clip R&d needs to head.” Mr Evans says lambs in the study were measured and scored for breech and tail bare area, breech wrinkle, dag, urine stain, bodyweight gain, survival and flystrike. “For survival and weight gain at day 90, clipped sheep were ahead of mulesed sheep and similar to unmulesed sheep. “For bare breech and skin wrinkle traits scores at day 90, clips were midway between no treatment and mulesing, and were significantly different from both. In line with onsite observations it appears that the skin wrinkle from clipped sheep compared with mulesed sheep improves further to day 180 and even later. “on one site with a reasonable level of fly challenge, clips provided good protection against flystrike at days 60 and 90. on a second site with a lesser fly challenge, clips also provided good protection against flystrike at day 60. “Besides providing a comparable level of protection against breech flystrike, the study confirms previous grazier and researcher observations about survival,weight gain and welfare benefits from using the clips.” Mr Evans says this study is an adjunct to the much larger, national product development and testing clip trial of 2007 – which assessed the performance of clips across a range of environments, sheep types and production systems – and also a universal clip trial, where different clips are compared against each other and with mulesed sheep. “Full biometrical analysis of all the data – about one million individual measurements – from the national 2007 clip trial continues and will be presented to industry as soon as the analysis is completed and a report compiled,” he says. ú More information: ian evans, awi project manager for blowfly control, firstname.lastname@example.org; www.wool.com.au/2010 Clips will prove to be an important flystrike management tool for a large proportion of australian woolgrowers from 2009 onwards.
