Monitoring of feeds selenium status in a southeast region of Romania.
One hundred and eighty-five samples of feeds (hays, green plants, and concentrate feed) from households covering 41 localities in Dobrudja, a southeast region of Romania, were collected and analyzed for selenium (Se) content by spectrofluorometry with 2,3-diaminonaphthalene. Only 6.5% of the samples analyzed were, in terms of the feed Se content, considered appropriate (i.e., 0.15-0.30 ppm), within the normal range. The remaining 93.5% proved to be Se deficient; the results fell into the 0.001-0.150 ppm range. Consequently, the samples were divided into three deficiency groups based on the content recorded as follows: severe for 3.2% (Se below 0.01 ppm), critical for 84.9% (Se in the 0.01-0.1 ppm range), and marginal for 5.4% (Se in the 0.1-0.15 ppm range). Conclusively, the Dobrudja feeds may be said to be generally Se deficient, which requires prophylactic and therapeutic measures to correct animal selenium deficiency.
