Why worm sheep?

Worming a lambIt is essential to regularly worm sheep to preserve their health and maintain a good balance within the flock.

The presence of internal parasites weakens the animals, causes digestive disorders, and leads to weight loss. Proper management of parasitism in sheep helps prevent these issues.
A healthy sheep, free from parasites, has better weight gain, better quality wool, and increased fertility.

With the arrival of cold weather, sheep spend more time in the barn, which promotes parasitic contamination. It is therefore crucial to worm them before winter to limit the spread of parasites and preserve the health of the flock.

In short, worming your sheep is primarily about taking preventive action.

When and how to worm sheep?

Worming should be done several times a year. Ideally, intervene before bringing them into the barn in the fall to limit the presence of parasites during the winter.

Before treatment, carefully observe your sheep: a dull coat, loss of appetite, or soft droppings may indicate an infestation.

During administration, always follow the dosage appropriate for the weight of each animal and remember to alternate worming types to prevent resistance development.
