Parasitology

The economic losses from worm parasite infections of cattle can be significant.  Calves under one year of age are more susceptible than older cattle who frequently have been exposed to the parasites and have developed a degree of immunity.

Adult worms in cattle produce eggs that are passed in the manure.  The eggs hatch, producing larvae that develop and move up onto the pasture grasses where cattle consume them.  Eggs can survive the winter and hatch out with warm weather.  Infection is most likely to occur when temperatures are warm and there is adequate rainfall.

Test Method: Routine fecal Flotations to screen for parasites.  Total egg counts are done using the Wisconsin Method.

Sample Requirement: Fresh or frozen fecal sample

Lab Testing Time- 1 to 2 hours (run daily)
