Abstract
One-hundred-sixty-six fleeces shorn from Rambouillet and Columbia rams involved in the 1975 and 1976 Wyoming Ram Performance tests were studied. All rams were shorn prior to the test and then offered a common diet for 150 days. Fleeces grown during that period were sampled by taking either 32 or 62 12.7 mm cores from alternate fleeces. All fleeces were then scoured individually. Estimates of clean wool per fleece based on the two sampling procedures were compared to clean wool content determined by scouring entire fleeces.
Simple correlations between clean wool determined by scouring whole fleeces and estimated from 62 or 32 cores were .992 and .983, respectively, in 1975, and .957 and .972 in 1976. The data suggest that clean wool content of individual fleeces can be determined accurately and economically from core samples.
