- Amounts to be administered and administration route
For external use only.
Quantity of Butox® 50 needed for 100 litres of water
Plunge dip treatment
Frequency of treatment recommended:
Mange mites: For curative treatment, two treatments at an interval of ten days should be made. For routine treatment, a single treatment every six months is recommended.
Lice: Usually, a single treatment provides protection against lice, depending on the infestation degree.
Ticks: Treatment should be repeated depending on the level of infestation.
Flies: A single application provides protection against flies for 6 to 8 weeks depending on the infestation degree, fly species and weather conditions.
A pre-mix with Butox® 50 is made by adding a small quantity of water to the required quantity of Butox® 50. This pre-mix is distributed along the length of the dip and stirred thoroughly before the remaining quantity of water is added. By passing through the dip, the first 20 animals will mix the dip and therefore need to be treated twice.
b) Topping up:
After the treatment of a herd or when the dip volume has fallen by 10% of its initial volume, topping up should be carried out, adding the necessary quantity of water and Butox® 50.
c) General instructions:
Before starting the dip treatment, stir thoroughly. Ensure that the animals are neither tired nor thirsty before treatment. Do not treat the animals during very hot weather.
A pre-mix with Butox® 50 is made by adding a small quantity of water to the required quantity of Butox® 50. This pre-mix is stirred thoroughly before the remaining quantity of water is added.
Each treatment should use a minimum quantity of 3 litres of diluted product per animal, paying particular attention to the preferential sites of parasites.
For treatment of mange mites, a preliminary brushing is recommended.
