Duration Team and Leader Alistair Carson Organisations Involved  Alistair Carson (ARINI) and Maurice McCoy (VSD) Background and Summary Effective control of gastrointestinal parasites is crucial in maintaining good health and performance of lambs and thereby minimising labour requirements in sheep production systems. The indiscriminate use of wormers is likely to be inefficient from a labour and economic point of view and even more importantly this type of parasite control is under threat from the growing resistance of the infectious nematode parasites to available...

Duration 4 years Team and Leader Jim McAdam (APSD), Lynne Dawson and Alistair Caron (ARINI) Organisations Involved Animal Plant and Science Division and Agriculture Research Institute of Northern Ireland Background and Summary Current research evaluating the potential of crossbred ewes to improve lamb output and carcass quality in the hill sector has demonstrated significant improvements in prolificacy and lamb output at weaning through the use of Lleyn X Blackface, Swaledale X Blackface and Texel X Blackface ewes relative to purebred Blackface ewes.  However the...

Duration 4 years Team and Leader Dr Lynne Dawson Organisations Involved ARINI, Hillsborough Background and Summary Previous research has demonstrated that crossbred ewes have a role to play in improving output in the hill flock (Carson and Dawson, 2005).. To date results indicate that, relative to purebred Blackface ewes, Lleyn X Blackface ewes have the potential to increase the number of lambs born by 21%, number of lambs reared by 24% and lamb output at weaning by 24%.  Texel X Blackface and Swaledale X Blackface ewes also demonstrated increases in lamb output at weaning by...
