Summer is when your cows should be performing at their best. Here are 3 signs worth keeping an eye on.
1. A persistent cough after moving paddocks.
That's a classic early sign of lungworm. Don't put it down to dust or the weather without ruling it out.
2. Milk yield dipping with no obvious cause.
Gut worms can quietly rob litres from your tank with no visible symptoms. Research suggests a significant burden can cost more than 2kg per cow per day.
3. Cows losing condition despite good grass.
Parasites divert energy away from production and towards the immune response. Your cows can look fine and still be losing ground.

If you're hearing a cough going through the milking herd a few weeks after turnout, here's what it might be.

Lungworm (hoose) is one of the most common causes of coughing in dairy herds at grass. It can move through a herd fast, and it's not just young stock that are at risk.

Adult cows can get hoose again, even if they've had it before. Immunity to reinfection can fade within just a few months of low exposure.

Your dairy cows do their best work on summer grass. But while our climate is perfect for growing it, it's also perfect for the parasites that can quietly work against your herd all season.

Understanding parasite pressure, including lungworm, gut worms and external parasites, is one of the most practical things you can do to protect your yield, your cows' condition, and your milk cheque this summer.

Follow Farm Health First for practical weekly guides over June and July. And as always, speak to your vet (IE) or vet/SQP (UK) for advice tailored to your herd.

Your cows look well. They're eating well. But something might be quietly holding your milk yield back.

A significant gut worm burden can reduce milk yield by more than 2kg per cow per day, with no obvious symptoms. No scouring. No coughing. Nothing you'd easily spot.

The parasite responsible, Ostertagia, is one of the most economically important in Irish and UK dairy herds. It affects how the stomach processes feed, and diverts energy that should be going into milk towards the immune system instead.

The good news? There's a practical way to find out where your herd stands. Bulk milk tank antibody testing (ODR testing) gives you a picture of the gut worm pressure your herd is working against right now.

Ask your vet (IE) or vet/SQP (UK) about it.

Use medicines responsibly. Always seek advice from your vet or SQP.
