Where possible, breeding should also be arranged so that ewes lamb from February to April to ensure that lambs will be adequately protected by maternal antibodies during the time of the year that this disease occurs. Annual vaccination is recommended.DOSAGE: Cattle, sheep and goats: 1 ml subcutaneously.
