	abstract = {<p>Intestinal parasites are a significant impediment to the productivity of grazing livestock in New Zealand (Scott et al. 2008). They are regarded by New Zealand sheep farmers as their most important animal health issue (Lawrence et al. 2007). The New Zealand deer industry estimated that parasites cost as much as 5\% of the total farm revenue (Mackintosh \&amp; Wilson 2003). On most farms controlling parasites in order to minimise their impact on animal performance relies heavily on the use of anthelmintics (Lawrence et al. 2007), but their continued usefulness is threatened by the development of worm populations resistant to these drugs (Waghorn et al. 2006a, 2006b). Studies aimed at developing more sustainable worm management practices will be important for maintaining the future productivity and profitability of many farming operations.</p>

	abstract = {Anthelmintic (drench) resistance in New Zealand{\textquoteright}s ruminant livestock is arguably the biggest single threat to sustainable future pastoral production. Clinical and sub-clinical parasitism impacts not only on animal health, but on animal welfare, and hence the image of pastoral production systems, total production and production efficiency and has a marked impact on the economic bottom line for both farmers and the country as a whole. In 2001 it was estimated for the relatively small NZ deer industry alone (worth $311 million in export earnings) that parasitism cost $12.8 million per annum in production losses due to parasitism and parasite control (Mackintosh and Wilson, 2002).},

	abstract = {The relationship was investigated between the number of days each  fortnight spent grazing Lotus corniculatus (lotus) or ryegrass/white clover  and dags, flystrike and growth rates in lambs. Lambs which grazed lotus for  7 or more days each fortnight had significantly fewer dags (86-113g) and  significantly higher live-weight gains (160-104 g/day) than lambs grazed on  ryegrass/white clover (154g, P<0.01 and 73g/day, P<0.05 for dags and live- weight gain respectively). Lambs which grazed lotus continuously had  significantly higher live-weight gains than lambs which grazed lotus for 7 or  less days each fortnight. Flystrike was positively correlated with dags  although this was less obvious over time-period 1 when the incidence of  flystrike was low. The incidence of flystrike differed significantly between  treatment groups ((2 P<0.001), ranging from 36\% of lambs struck in the all  ryegrass/white clover groups to 7\% in the all lotus groups. Wool growth,  faecal dry matter content and faecal nematode egg count (FEC) did not  differ between treatments. These results confirm the potential of lotus as a  tool in the management of dags and flystrike but indicate that lambs will  need to be grazed on lotus for 7 or more days each fortnight in order to  realise significant benefits. },

During winter, LWG (165 v 140 g/day; P<0.05) and VFI (1.62 v 1.20 kg   DM/day; P<0.001) were greater for animals grazing ARG than PRG pastures,   resulting in a greater proportion of deer attaining the target slaughter   weight (60 v 41\%).
