Agglutination or “clumping”
The reasons for agglutination or “clumping” are not well understood.
They include:
- Some studs report an increased incidence of agglutination during hot weather conditions.
- In some instances, especially with semen prior to extension, cells will clump when they contact the glass surface of the slide.
- Also, in some instances, failure to rotate the doses on a daily basis will result in clumping.
