Abstract: During the course of studies on selenium deficiency in sheep, selenium analyses were carried out on a number of miscellaneous materials. The results are recorded in Table 1. Selenium in dried scoured samples of wool ranged from 27 to 470 ng/g. As in the case of other animal tissues and products, the selenium concentrations were relatively low in areas where selenium responsive conditions occurred. The mean level in the wool of 10 sheep in a flock grazing pasture containing 10 ng/g was 33±5 ng/g whereas 490±43 rig/g was present in samples from a property in Northland where the selenium in the pasture was 216 ng/g. However, wool was not considered suitable as a diagnostic material in view of the laborious cleaning procedures which would be required in preparation of samples for analyses. selenium in some pig rations. The latter was among the first to question the adequacy of selenium in the diets of some New Zealanders, particularly of infants bottle fed on cows milk containing very low levels of the element…
