Dear all
Regular Monitoring worm egg counts in sheep and other livestock is a modern and important approach to sustainable worm control (e.g see SCOPS advice). For most gastrointestinal worm eggs of ruminants and horses You can do this yourself (UTube tutorials ) and save money. You need a McMaster slide (ebay, ONLY £15) and a basic microscope. You can make the flotation easily by dissolving as much table salt in a given volume of water and checking there is a sediment after leaving overnight. A compound microscope with overall magnification of 400 will suffice - x10 eyepieces and a x4 lens. Make sure you have the lighting correct and optics adjusted so you can focus correctly on the lines of the slide and air bubbles; any nematode worm eggs will be in the same focal plane. Note: immature worms do not produce eggs and a negative count does not mean the animal is free of worms; also fluke eggs and tapeworm eggs of horses will not show up using this salt method).
