R.  aLong-term effects of sheep body lice (Damalinia ovis) on body weight and wool production.h[electronic resource]  c1982  aAbstract: The effects of sheep lice on their hosts were monitored by comparisons between a lousy flock and a louse-free flock over 3 years from when the sheep were 4 months old. Lice had no significant effect on host body weight or greasy wool production. Lambing percentages and lamb weights at weaning also appeared to be unaffected. Although scoured wool yields from the lousy flock were reduced by 2.6% (mean) over 4 shearings in comparison with the lousefree flock, greasy fleece weights individually corrected for yield, using mean yields, did not differ significantly.  aEctoparasites  aLambs  aLice  aLiveweight gain  aParasites  aSheep  aOvino  aParasitologia  aEctoparasito  aWeight losses1 aLUKIES, J.
