Life cy­cles

EQUUS - - Eq Inbrief -

The de­tails of the life cy­cles of par­a­sitic worms vary some­what by species. But all have at least two phases: one in­side the horse and one out­side in the en­vi­ron­ment. Gen­er­ally, the adult worms in­side the horse lay eggs that exit the horse’s body with his ma­nure. When an­other horse grazes in the area, he may pick up ei­ther the par­a­sitic eggs or the hatched lar­vae (de­pend­ing on the species), which are swal­lowed and de­velop to ma­tu­rity in­side the horse.
