	abstract = {In addition to advantages offered to the lamb trade by the new  sheep breeds they also offer opportunities to the wool industry. The  influence of new breeds imported by Lamb XL on lamb and hogget wool  production and characteristics was examined for Texel, Oxford Down,  Whiteheaded Marsh and Finnish Landrace crossbreds compared with Romneys.  Fleece weights were similar for the Oxford Down, Whiteheaded Marsh and  Romney crosses but Texel crosses had a 12\% reduction in hogget fleece  weight.   Texel and Oxford Down cross hoggets produced wool with high bulk and  staple strength compared to the Romney cross hoggets. These  characteristics are currently of special interest in the wool industry,  with premiums existing for bulk and anticipated in the near future for  staple strength. There were no practical differences in other wool  characteristics between Romney, Texel, Oxford Down and Whiteheaded Marsh  cross hoggets including fibre diameter, yield, colour, vegetable matter  contamination and position of break. Finnish Landrace crosses produced  lighter, finer fleeces. However half Finnish Landrace crosses are  unlikely to be used in farming systems and reductions in fleece weight  will be lower in the anticipated quarter or eighth Finnish Landrace  crosses.   Lamb and hogget wool production and characteristics from the exotic  crossbreds compare favourably with New Zealand Romneys and offer  increases in wool production compared to traditional terminal sires.  },
