Milking Goats: Suitable for use in goats producing milk for human consumption (see withholding period).

Dosage
Always refer to the label. BZ’s generally have low toxicity but to avoid residue problems, it is good practice to separate into different weight classes if there is a large variation in age and weight.
Sheep and Goats: Dose at the rate of 1ml per 4kg body weight. It is preferable if sheep, lambs or goats are fasted for approximately 18 hours before administering BZ drenches. This may not be feasible for dairy goats.
Cattle: Dose at the rate of 15ml per 50kg body weight
