Notizen:
The permissible concentration of selenium which can legally be added to dairy cattle rations has recently been increased from 0.1 to 0.3 ppm. A feeding study with lactating dairy cows was conducted in which 0.3 or 0.6 ppm of selenium as sodium selenite was added to their diets for 23 and 26 days, respectively. Analysis of milk and blood throughout this period showed no consistent increase in the concentration of selenium in these fluids.
