Dosage and Administration


Dose the mob to the heaviest animal by liveweight in each group (ewes, wethers, rams and lambs). Do not underdose.

A representative sample of animals should be weighed before treatment either with scales or weighband. Where there is a large variation in size within the group, dose rate should be based on the label directions for each weight range. Drafting into two or more lines may be appropriate, to avoid excessive overdosing.

Safe to use on pregnant and non-pregnant animals of any age when used as directed.

Dose sheep and lambs at 1mL/10kg body weight.
