Fast Fact: Brown stomach worms cause indigestion

The burrowing and feeding activities of the fourth stage larvae of Teladorsagia circumcincta (previously called Osties) in the abomasal walls of sheep and goats interfere with the digestion of proteins, which results in scouring.

The cells of the damaged walls proliferate in an attempt to heal, but these cells are unable to produce the much-needed gastric acid. The abomasum becomes less acidic—the pH rises from about 2 to almost 7—and becomes more favourable to undesirable bacteria. Proteins that have not been digested properly in the abomasum pass into the small intestine and inhibit the absorption of fluids, which results in more watery faeces: diarrhoea or “scours”.

At this point, affected stock are in a bind; increased food intake is needed to compensate for inadequate protein digestion, but their appetites are also suppressed by the worms; weight loss is the result.
