Increasing selenium in bovine blood by feed supplements or selenium injections.
A study was made of the relative effectiveness of including various feed supplements or selenium injections on increasing the blood level of selenium in pregnant Holstein cows. The dietary treatment included the addition of soft coal fly ash, western grown grains, high selenium sweet clover or sodium selenite to the rations. Whereas each of the treatments caused a progressive increase in blood selenium the addition of 4% by weight of fly ash to the ration raised the concentration of selenium in blood the highest. Increases in the concentration of selenium in milk as a result of the treatments were very small.
