Tapeworms are one of the most common internal parasites you'll encounter.

Are your porkers growing poorly (or losing weight)? Do your dairy cows give less milk than they used to? Does your goat have white gums. Does your mutt mope?

When such “classic” symptoms show up, most any owner knows that his or her critters have internal parasites (commonly called worms). But maybe your animals aren’t acting all that sickly. Perhaps they just look a wee bit listless. Heck, maybe the beasts even appear to be as happy as cats in a milking parlor!

However, if you read Part I of this article (“How to Deal With Internal Parasites in Livestock“), you know that healthy-looking livestock can have serious worm infestations! To put it simply, parasites are the biggest medical problem we veterinarians have to face. So I know from experience that even when you don’t see a single indication of the internal freeloaders, you can be spending money, building feeders, raising thoroughbreds, and in general going to a whole lot of trouble all to provide vintage “pastureland” for some hidden (but enormous) herds of worms!  

Know Your Enemy (The Essential Parasite Primer)

You should understand—before you start tackling these foes—just what parasites do and where they come from. Worms—slimy “spelunkers” that range from microscopic to yardstick size—can invade almost every animal organ. The uninvited visitors will clog hearts, coat stomachs, cause acute bellyaches, block blood circulation, eat your stock’s food (or innards), and—in some instances—kill the “hosts” they inhabit.
