Dosage and Administration

A representative sample of animals should be weighed with either scales or a weighband. Dose the mob according to the heaviest animal by liveweight in the group (cows, bulls, calves, heifers etc). Do not underdose. Where there is a large variation in size within the group, draft into two or more lines based on bodyweight, to avoid excessive overdosing.

The formulation should be applied along the topline in a narrow strip extending from the withers to the tailhead. The dose rate is 1 mL for each 10 kg of liveweight. See the dosage table in the product images.
