FIELD: agriculture.
SUBSTANCE: invention relates to agriculture, in particular, to veterinary and sanitary helminthology. The device for determining the survival of eggs of nematodes in liquid manure is made up of plastic containers with volume of 1 litre or more, which upper part is cut on three quarters of the circumference to form a hinged lid. Holes in the upper and middle parts are made, as well as in the walls and bottom of the containers to close and sink them to the desired depth. The containers are interconnected through the required intervals with a twine made of synthetic material, which is attached to the load and a float.
EFFECT: invention is characterised with simple design and ease of use.
