Description
The development and migration of gastrointestinal nematode larvae on a range of herbage species were compared following a series of standardised contaminations with sheep faeces over two years. In 1992/93, greatest numbers of larvae were recovered from browntop (Agrostis capillaris cv Grasslands Muster), cocksfoot (Dactylis glomerata cv Grasslands Kara), ryegrass (Lolium perenne cv Grasslands Nui) and Yorkshire fog (Holcus lanatus cv Massey Basyn) while the lowest numbers were recovered from white clover (Trifolium repens cv Grasslands Huia) with the other herbages intermediate. In 1993/94, highest numbers were recovered from Yorkshire fog and ryegrass, lowest numbers from white clover, chicory (Chicorium intybus cv Grasslands Puna) and lucerne (Medicago sativa cv Grasslands Otaio) and intermediate from the other herbages. The proportions of total larvae recovered in the 0- 2.5 cm stratum, an inverse measure of larval migration, were lowest in white clover, ryegrass, tall fescue (Festuca arundinacea cv Au Triumph) and browntop, highest for Yorkshire fog and intermediate for the other grasses.
