Dose to be administered and administration route

On completion of each treatment cycle of the product and before the dosing gun is stored, immediately expel any remaining product in the dosing gun.

Failure to use the product as directed may result in suboptimal parasite control.

Administer by means of a Crovect Pour-On Gun as follows:

Blowflies:

Prevention of blowfly strike

Bodyweight	Dose	Doses per litre
Up to 25 kg*	20 ml	50
25 to 40 kg	30 ml	33
Over 40 kg	40 ml	25

*Do not administer to animals of less than 12.5 kg bodyweight.

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.

Lice: 5 ml per 20 kg bodyweight up to a maximum of 20 ml.

Bodyweight	Dose	Doses per litre
Up to 20 kg	5 ml	200
21 to 40 kg	10 ml	100
41 to 60 kg	15 ml	66
Over 60 kg	20 ml	50

Using the straight nozzle on the Pour-On Gun, apply as a pin-stream from the shoulders to the rump along the middle of the backline. Sheep may be treated off- shears or at any time during the year.

Ticks: Adult sheep and lambs greater than 10 kg: 10 ml per 20 kg bodyweight, up to a maximum of 40 ml. One treatment will give 10 weeks cover.

Lambs under 10 kg: 5 ml followed 3 weeks later by a 10 ml application.

Bodyweight	Dose	Doses per litre
Up to 10 kg	5 ml	200
11 to 20 kg	10 ml	100
21 to 40 kg	20 ml	50
41 to 60 kg	30 ml	33
Over 60 kg	40 ml	25

Using the straight nozzle on the Pour-On Gun, apply as a pin-stream from the crown of the head (see section 4.5 (i) regarding avoidance of the eyes) to the top of the rump.

Headflies: 5 ml per animal irrespective of size.

Apply to the top of the head between the ears using the T-bar nozzle. Take care not to apply product in the sheep’s eyes.

One application before the start of the headfly season will give up to 4 weeks protection.

Re-treat as required.

This product contains a blue dye to aid in the identification of treated animals. The colour is temporary and will fade from the fleece within 48 hours of application.
