Over the past 30 years, many different antibiotics have been used on feedlots as feed additives at subtherapeutic levels to. increase rate of growth of animals and to improve feed efficiency. Penicillin and the tetracyclines have gained widespread use as feed additives; however, there is a growing concern about the use of these antibiotics in feeds, and the possibility of these antibiotics giving rise to populations of new strains of bacteria resistant to other antibiotics and/or resistant to subsequent treatment of sick livestock, and the transmittance of such new strains to human beings resulting in untreatable human diseases (Adams 1975, Kiser 1976, Hirsh and Wiger 1978, Solomons 1978, Visek 1978).
