Story: Diseases of sheep, cattle and deer

There may be hundreds of thousands of internal parasite worms in a cow’s gut, and each gram of dung dropped can contain thousands of eggs that will hatch on the pasture into microscopic larvae ready to be eaten by other stock. Young stock are most affected by these internal parasites and need early drenching with an anthelmintic, or special management, to keep numbers low. Older cattle such as these may also require strategic drenching.
