4.5 Special Precautions For Use

i) Special precautions for use in animals

Vectocert 1.25% w/v Pour-On Solution for Sheep minimises mothering-up problems after treatment. However, care must be taken not to apply the product right to the lamb’s tail, as a ewe recognises a young lamb partly by the smell of the tail area.

Blowflies are attracted by dirty, damp wool or open wounds. The more common site for fly strike is the rump due to soiling caused by diarrhoea and urine staining. The efficacy of Vectocert 1.25% w/v Pour-On is reduced in the presence of soiled or dirty wool. Therefore, sheep must be crutched(dagged) regularly and appropriate worm control measures employed.

Take care not to apply product in the sheep’s eyes. This precaution should be observed particularly when treating breeds with little wool on their heads.

Full operating and maintenance instructions, including details on the use of nozzles are supplied with each applicator gun. Please read carefully before use. Maintain applicator gun carefully to ensure accurate dosage.

For external use only.

ii) Special Precautions to be taken by the person administering the product to animals

Apply as a fan-spray to the surface of the fleece on the back and hindquarters of the sheep using the Pour-On Gun fitted with the fan-spray nozzle. Half the dose should be applied to the shoulders, back and flanks, and half to the rump. The distance between the nozzle and the fleece should be approximately 20 cm. Each dose will require 2 or 3 sweeps to apply. THE PRODUCT WILL PREVENT BLOWFLY STRIKE ONLY ON AREAS COVERED BY SPRAY. One application will give 6-8 weeks protection. Re-treat as required.

Treatment of blowfly strike

Apply directly to all the affected parts at the rate of 2.5 ml per 100 –150 cm²(roughly the size of a hand). The T-bar nozzle should be used. Most strikes will require 5-10 ml. Ensure that all affected parts are treated. A single application is sufficient to ensure that larvae are expelled and killed within a few hours.
