	abstract = {Hoggets from the Massey University fleeceweight-selected (FW)  line were previously shown to have lower sulphur (S) concentrations in  midside wool than control (C) hoggets at 14 months of age. This study  involved two experiments. The first examined wool S concentrations at  different body positions in 14-month hoggets and the second examined  midside wool S concentration and blood parameters in young lambs. In  Experiment 1, 16 FW hoggets and 16 C hoggets were wool sampled at 11  positions over the body. The wool S concentration of FW hoggets was  found to be significantly (P<0.01) lower than that of C hoggets (2.77\%  vs 2.94\%). Discriminant analysis was used to classify hoggets to their  respective lines based on wool S measurements. The combination of sites  which most correctly classified the hoggets was the midside plus base of  the tail. In the Experiment 2, 40 FW and 40 C lambs were wool sampled  on the midside at 28 day intervals from 21 November (1 week before  weaning) to 13 February. FW lambs had significantly (P<0.05) lower  midside wool S concentrations of urea, but not of creatinine, than C  lambs. Results suggest that wool S concentration and plasma urea  concentrations may be useful genetic markers for high fleece production  but that the ability to discriminate between animals of high versus low  genetic merit for fleece weight on the basis of wool S will depend on  the sampling position and age of animals.  },
