	abstract = {Lambs grazing the tannin containing pasture species Lotus  corniculatus (cv Goldie) were compared with lambs grazing a high  endophyte ryegrass (cv Nui) in order to assess the effectiveness of lotus at  reducing dags and flystrike. Two trials of the same design were run  consecutively, between January and April 1994. Each of 4 paddocks, 2 of  lotus and 2 of ryegrass, were set stocked for 32 and 42 days (respectively for  trials 1 and 2) with 62 lambs. Half of the lambs in each paddock were  drenched fortnightly with a combination anthelmintic. Lambs were  examined for flystrike three times each week and samples were collected for  fly identification before strikes were treated with insecticide.   Lambs which grazed lotus suffered less flystrike than those grazed on  ryegrass in both trials (32\% of 51\%; P<0.01 and 1.5\% cf 7.4\%; P<0.05 for  trials 1 and 2 respectively). Drenching reduced flystrike in trial 1 (from 57\%  to 26\%; P<0.01), but not in trial 2 (4.8\% cf 4.1\%; NS). Flystrike was  strongly correlated with dagginess (R2=97\%). Mean dry weight of dags was  reduced by grazing lotus rather than ryegrass (79g cf 108g; P<0.01 in trial 1  and 9.7g cf 14.3g; NS in trial 2) and by drenching (68g cf 118g; P<0.01 in  trial 1 and 8.8g cf 15.2g; NS in trial 2). Lambs grazing lotus had  significantly (P<0.01) higher faecal dry matter content than those grazing  ryegrass. We conclude that lotus has considerable potential for a future role  in the integrated management of flystrike and dags.  },
