Methods of selenium supplementation of ruminants

  2. JS Chalmers

Abstract

Three methods of selenium supplementation, by subcutaneous injection, intraruminal pellet and addition to water, were tested in experiments with cattle and a fourth method, oral supplementation of a sodium selenite solution, was evaluated with lambs. All four methods worked effectively for periods ranging from four months to one year after treatment. It is suggested that choice of treatment will depend on the circumstances of each case, including cost, husbandry system and ease of administration.
