Abstract

In a series of trials in Florida, crossbred beef females were fed different chlortetracycline (CTC) regimes relative to weaning and breeding to determine effects on fertility. In trial 1, alternately sorted crossbred yearling heifers were either given CTC at 1.1 mg/kg/day for 30 days before natural breeding (T, n=225) or no CTC (C, n=225). More pregnancies occurred in the treated group compared with controls (71.5% and 56.8% respectively). In experiment 2, crossbred yearling heifers were placed in 3 comparable groups after 3 months postweaning CTC at 1.1 mg/kg/day; A (n=106) controls, B (n=97) CTC at 22 mg/kg/day for 5 days prebreeding, then 1.1 mg/kg/day for the first 30 days of breeding, C (n=101) CTC at 1.1 mg/kg/day for the first 30 days of breeding. Groups did not differ in numbers of pregnancies (overall 71.6%) although days pregnant tended (P, The Bovine Practitioner, Vol. 33, No. 2 (1999 May)
