title: Effect of low level feeding chlortetracycline on subsequent therapy of chicks infected with Salmonella typhimurium.
abstract: A six-week trial was conducted to determine if therapeutic use of chlortetracycline (CTC) would be affected by previous use of the same antibiotics at subtherapeutic levels in the feed. Results indicated therapeutic effect of CTC on mortality was not compromised by the previous use of the low level antibiotic.
