Summary

The copper, molybdenum, and total sulphur contents were estimated in 124 samples of oats and 67 samples of barley obtained from various parts of Northern Ireland. Copper contents were in the low-normal range, the average of all oat samples being 3–9 ppm and of barley samples 4–9 ppm, and the range 1–5 to 8–4 ppm covering all samples analysed. The corresponding averages for molybdenum were 0–25 ppm and 0–30 ppm, about 10% of the samples in each case containing less than 0–02 ppm. Sulphur contents (expressed as sulphate) ranged from 0–23 to 0–46 %. The low molybdenum contents are considered to be of significance in the copper metabolism of housed sheep.
