 Lifecycle: After
a horse swallows small strongyle larvae, they burrow into the intestinal
wall, mature and emerge into the large intestine where they feed and
lay eggs. Eggs are passed in manure and develop into infective larvae
in the grass.
How
It Gets Into Your Horse: Small strongyle larvae are swallowed as
your horse eats infected grass.
Dangers If Left Untreated: Horses severely infected
with small strongyles can suffer weight loss, diarrhea
and colic.
