We all appreciate the transition into housing is a risky time for first grazing season animals, there are so many things to consider; dietary change, weaning, grouping, respiratory disease, and how to control parasites specifically fluke and worms.
For a successful housing time, both internal and external parasites must be accounted for;
Gut worms - Reduced weight gain, carcass quality and a cost to the immune system of controlling parasites. Costs have been put at a 30% reduction in growth rate1, and 30kg difference at finishing for animals with good control at the time of housing2.
Lungworm - Coughing, weight loss and in severe cases death. With a cost to the immune system of controlling parasites and predisposing to respiratory disease. An average of 1-7% mortality rate, although it is likely that subclinical infections could be of far greater economic relevance3.
Fluke - Reduced live weight gain, treatment costs and a cost to the immune system of controlling parasites. The cost of fluke to the UK industry has been estimated at £23 million4, with an extra 80 days to reach slaughter weight costing between £25 and £35 per head5.
Lice - Anaemia from high burden of sucking lice. Pruritus (itching) leading to less time eating and lying meaning decreased weight gain. It is difficult to quantify, but has been put at a cost of millions of pounds to the UK cattle industry5.
When is worm control required?
All animals that have had a grazing season will require worm control at housing, unless they are still in the persistency period of a previous treatment, animals can be cleaned out with a persistent product prior to housing to give enough time for the immune system to recover to smooth transition. If not, worming must be done at housing as, utilising a wormer post housing has very limited value, worms suppress appetite6, lowering the chances of successful transition to winter diet meaning a growth rate check at housing - Do not compromise on housing worm control.
When is Lice control required?
Lice are always a risk in housing in winter, they are spread by close contact between animals and rubbing on feed barriers and at water troughs, for a successful housing period avoiding handling and multiple costly treatments is essential, choose a product that will fit your system and ideally one with a Lice Free Guarantee – Do not compromise on Lice Control.
What are my treatment options?

The triclabendazole in the pour-on gives the greatest spectrum of activity against the different maturities of fluke of any pour-on, without the complications of having to drench the cattle. Alongside biting and sucking lice control with a Lice Free Guarantee, Do not compromise on your housing treatment.
