Developed by New Zealand sheep farmer, Mr David Brown, in the early1990s, Woolover all-wool lamb covers have saved hundreds of thousands oflambs around the world. Woolovers are now manufactured in Australia. Formanagement reasons lambing is most often carried out at a time of theyear subject to adverse conditions, putting survival of many lambs atrisk. There is no doubt that fitting a Woolover cover as soon aspossible after birth can turn losses into profits. Lamb mortality can bedramatically reduced. Not only are survival rates increased, but trialshave proven lambs in Woolover covers gain 2/3 of a kg more weight intheir first three weeks compared to uncovered lambs. The reduced feeddemand on the ewe ensures she does better too. Woolover covers should beapplied to all lambs under 4 days old when a storm is imminent. Coverscan reduce losses from 60% or more to almost none, within this group. Itis recommended that covers are left in place for up to 3 weeks (removeat docking time) to get maximum benefit, but if there is substantialimprovement in the weather, covers can be removed and re-used forgreatest economy. Woolover covers can be applied in about 30 seconds.The tail end is rolled forward and the lamb´s front legs, and then head,are inserted through the front holes (just like putting on a jersey).The tail end is then unrolled and the rear legs pulled through theholes. Care should then be taken to pull the cover up all the legs so itis snug against the lamb´s body. Survival is then assured in even verybad weather conditions. Woolover covers can be washed and re-used ifremoved after 3-4 days. Covers should not be left on lambs for longerthan 3 weeks, except for exceptionally small lambs.
