Abstract: In an artificial vagina for use in animal artificial insemination that includes a tubular section with an intromission orifice, a thin, flexible plastic sheet liner of a generally cylindrical shape with an intromission opening and a collection chamber is insertable into the artificial vagina, and disposable after one use. A filter mounted on a ring is located within the liner at a reduced diameter portion located intermediate the collection chamber and the main portion of the liner. An external strap frictionally engages the ring to secure the filter.
