title: A study of drug residues in milk following intrauterine infusion of antibacterial drugs in lactating cows.
abstract: Intrauterine infusion of nine antibacterial compounds caused detectable drug residues in 17 out of 165 cows or in 25 out of 1110 posttreatment milkings. Four cows treated with pyrolidinomethyl tetracycline suspension had drug residues at the first milking. One cow had residues after oxytetracycline treatment, two after procaine penicillin G, three after acriflavin and after chloramphenicol-dapsone and four after hibitane. Nitrofurazone, nitrofurathiazide and Hibitane Compound(R) did not cause detectable inhibitory residues in any milk sample.
