	abstract = {A replicated trial with 4 stock rates of {\textquoteright}wet{\textquoteright} ewes (9.0, 10.5,  12.0, 13.5 sheep/ha) and 4 stocking rates of {\textquoteright}dry{\textquoteright} ewes (11.0, 13.5,  16.0, 18.5 sheep/ha) was established at the DSIR Grasslands {\textquoteright}Ballantrae{\textquoteright}  Hill Country Research Station to enable hill country farmers to make  informed decisions as to the economics of farming breeding or unmated  ewes.   Stocking rate had a large effect on liveweight throughout the year with  the greatest effect being in winter. Mean weaning weight of lambs was  25.4 kg at 9.0 ewes/ha and 19.7 kg at 13.5 ewes/ha.   Dry ewes grew more greasy wool/ha than wet ewes (P<0.05). Greasy wool  production ranged from 41.6 kg/ha at 9 wet ewes/ha to 81 kg/ha at 18.5  dry ewes/ha. At 13.5 sheep/ha dry ewes grew 28\% more greasy wool than  wet ewes which reared 1.2 lambs to weaning. November/December fleece  weight/ha was unresponsive to increasing stocking rate for both wet and  dry ewes (P<0.01). November/December fleeces were 18.6\% heavier from  ewes in paddocks having a sunny aspect than in paddocks with a  predominantly shady aspect (P<0.001). Slowest wool growth occurred  during August, being 5.3 to 8.3 mm/month and maximum wool growth  occurred during January within the range 17.3 to 18.5 mm/month.  },
