Why it’s important to house your cattle with a ‘clean set of lungs’
When it comes to parasite control at housing it is worth considering a Pre-Housing Dose (PHD).
A PHD is highly practical and offers your cattle both significant production and health benefits.
Lungworm or hoose is probably the most significant parasite for Irish cattle being housed in the autumn. Not only do adult lungworm cause irritation and obstruct the airways, the immature stages (larvae) damage the lung tissue while migrating through it before reaching the airways.
This causes the lungs to function less efficiently and makes them more prone to invasion by other bugs like viruses and bacteria. The larvae and adult lungworms are killed and removed quickly after dosing but it can take two to three weeks for the lung tissue to heal afterwards.
This is where the PHD comes in; would it not be better to treat lungworm infections while the weanlings are still at grass, in a healthy outside environment, to allow healing to occur without the challenges of dust and viruses etc?
This does not mean more doses because there are wormers that have a persistent effect against both lungworm and stomach worms.
What wormers qualify to be used as PHDs?
- Cydectin Pour On,
- Cydectin 1% Injection,
- Cydectin TriclaMox Pour On
- Both Dectomax injection and Pour-On
All have at least five weeks persistent activity against both lungworms and stomach worms.
