Pesky Parasites in young stock

Reaching targets with youngstock are super important to set them up for life! Ensuring youngstock are supported through drench protocols and mineral supplements are vital for the growth and longevity of your cattle.  

When is a good time to drench?

Now! Many youngstock are going off to winter grazing so it’s the perfect time to drench before they leave.

Frequency of drench administration is dependent on how long the products last and the animal’s exposure to worm burden. However, a good rule of thumb is to start drenching at weaning every 4-6 weeks through until winter. As animals grow older, their immunity develops, and the frequency of drenching can reduce.

Why should I drench?

Parasites cause unwanted clinical signs such as scours, ill-thrift, poor growth, and rough coat. Keeping on top of parasite management is vital in meeting growth targets for young animals to set them up with a great immune system and support them as they enter the busy life of a dairy cow.

Ensure you are following drenching best practices to get the most out of your drench. This includes weighing the mob and dosing to the heaviest animal, ensure the drench gun is working correctly, and using the correct technique.
