Best Practice For Cattle Pour On Wormers

Tuesday, 16th February 2016

One of the most common problems in the development of wormer resistance in the agricultural industry is the inaccurate use of the licensed medicines used to treat parasites in cattle and sheep.

One of the most popular formulations of wormers for worming cattle are pour-on applications due to their ease of use. However, it is important to still use these products accurately. Merial have produced this tutorial video to show best practice when using pour on products on cattle.

It is important to remember that not only do you need to follow the steps as outlined in the video – assessing the weight of the animal correctly, wearing the correct protective clothing and calibrating the pour on gun – but you also need to establish that the gun is functioning correctly and giving the correct dose of the product. Lots of farmers use old and ineffective dosing equipment which inevitably leads to under-dosing and eventual resistance. It is also important that the products are applied in dry conditions.

Not only will these practical steps help to reduce the development of anthelmintic resistance, it will also mean that the cost of these products is not wasted – if the animal is under-dosed then the product will not be effective and the time and money spent on treatment will be wasted.
