Q: Are the eggs from large or small strongyles?
A: The eggs from large and small strongyles appear very similar and cannot be differentiated. The eggs must hatch and then the larvae can be identified as large or small. Research has shown that eggs found today in most situations are 95% small strongyles because Ivermectin use has nearly eliminated the large strongyles.
Q: Do you only check for strongyles?
A: Horsemen's Laboratory looks for other worm eggs, but seldom finds any; this may be due to the fact that over 80% of our horses are adults over 4 years of age. If they are found they are certainly reported.
