Patent ID: 7217239

Claim:
An apparatus for collection of semen comprising: i) a frame forming an elongate generally horizontal body having a rear entry end; ii) a base supporting and elevating the body; iii) a tubular receptacle containing an artificial vagina having a rear entry opening, a rear end portion, and an inner end portion, said rear end portion pivotally carried on opposite lateral sides within the body, and said inner end portion releasably carried within the body; so that when the inner end portion is released collected semen therein will drain downwardly to an inner end portion of the artificial vagina; and, iv) a recessed rear access door, said door having an inner side portion positioned adjacent to the opening in the rear end portion of the tubular receptacle and an outer side portion positioned within an interior peripheral top and lateral side portions of the rear entry end of the body, so that downward and lateral components of thrust load exerted by the horse are largely sustained not by the door, but by the frame of the body, and wherein said door also has an enlarged thickness accommodating a funnel shaped opening in the exterior side portion thereof so that the horse's penis is guided and funnelled into a central opening in the door.
