  • LIQUAMYCIN LA-200 is to be administered by subcutaneous, intramuscular, or intravenous injection to beef cattle and calves, including pre-ruminating veal calves.
  • Single dosage of 9 mg/lb is recommended for treatment of bacterial pneumonia (shipping fever) associated with Pasteurella spp. and Haemophilus calves and yearlings or infectious bovine keratoconjunctivitis (pinkeye) caused by Moraxella bovis. For treatment of foot rot and other indicated diseases, a dosage of 3-5 mg/lb body weight per day is recommended.
  • LIQUAMYCIN LA-200 can also be administered by subcutaneous, intravenous, or intramuscular injection at a level of 3-5 mg of oxytetracycline per lb of body weight per day. In the treatment of severe foot rot and advanced cases of other indicated diseases, a dosage level of 5 mg/lb of body weight per day is recommended. Treatment should be continued 24-48 hours following remission of disease signs; however, treatment should not exceed a total of four consecutive days. Consult your veterinarian if improvement is not noted within 24-48 hours of the beginning of treatment.
  • LIQUAMYCIN LA-200 is intended for use in the treatment of disease due to oxytetracycline-susceptible organisms in beef cattle and calves, including pre-ruminating veal calves. A thoroughly cleaned, sterile needle and syringe should be used for each injection (needles and syringes may be sterilized by boiling in water for 15 minutes). In cold weather, LIQUAMYCIN LA-200 should be warmed to room temperature before administration to animals. Before withdrawing the solution from the bottle, disinfect the rubber cap on the bottle with suitable disinfectant, such as 70% alcohol. The injection site should be similarly cleaned with the disinfectant. Needles of 16-18 gauge and 1-11.2 inches long are adequate for subcutaneous and intramuscular injections. Needles 2-3 inches long are recommended for intravenous use.

Subcutaneous Administration: Subcutaneous injections in beef cattle and calves, including pre-ruminating veal calves, should be made by directing the needle of suitable gauge and length through the loose folds of the neck skin in front of the shoulder. Care should be taken to ensure that the tip of the needle has penetrated the skin but is not lodged in muscle. Before injecting the solution, pull back gently on the plunger. If blood appears in the syringe, a blood vessel has been entered; withdraw the needle and select a different site. The solution should be injected slowly into the area between the skin and muscles. No more than 10 mL should be injected subcutaneously at any one site in adult beef cattle; rotate injection sites for each succeeding treatment. The volume administered per injection site should be reduced according to age and body size so that 1-2 mL per site is injected in small calves.

Intravenous Administration: LIQUAMYCIN LA-200 may be administered intravenously to beef cattle. As with all highly concentrated materials, LIQUAMYCIN LA-200 should be administered slowly by the intravenous route.
