摘要

Four hundred West Otago and Southland farmers were sent a questionnaire on shelter for lambing, and 137 responded. They estimated exposure losses at 6#x2013;10 and considered shelter very important to lamb growth. Eighty#x2010;two percent intended to plant shelter. Ewes with lambs less than 3 days old were more likely to seek shelter than ewes with older lambs, and pre#x2010;lamb shearing increased sheltering. Young lambs had highly variable sheltering behaviour. Ewes (especially if shorn) sought lambing sites with shelter or large objects. Farmers rated wool lamb covers more highly than plastic covers for effects on survival and growth, ewe acceptance, and cost#x2010;effectiveness. For vegetative shelter, trees or flax on windward and leeward sides, or around inside edges of paddocks, were best. Common genera used wereEucalyptus, Pinus, Phormium, Populus,andCupressus. PhormiumandPopuluswere most easily established andPinusandPhormiumwere most effective. Hay bales, sheds, and materials covering fencelines were also used.
