A.H. Swine 5
The use of antibiotics and certain other antibacterial agents in rations for growing swine has been hailed as one of the most important developments in swine nutrition in the last ten years. Although the use of antibiotics has become quite commonplace in swine rations, their continuous use in swine feeds has raised the question as to whether an antibiotic loses some of its effectiveness when fed continuously in a swine feeding program. The object of this experiment was to determine the effect on rate of gain and feed efficiency of some of the newer antibiotics in relation to an antibiotic (chlortetracycline) that has been fed in the South Dakota Station herd for a number of years.
