Worms
The most significant types of worms in cattle in Ireland are:
- Gutworms (Cooperia oncophora, Ostertagia ostertagi)
- Lungworms (Dictyocaulus viviparous)
General symptoms of worm infections are rough hair coat, diarrhea, emaciation, weight loss, and/or blood loss. External parasites symptoms are hair loss (lice), scabs (mites), lumps on back (grubs), or blood loss (flies, sucking lice and ticks) and weight loss.
