[Phantoms for the collection of genital secretions in stallions].

This study outlines the use of a device known as a phantom for collecting genital secretions from stallions for research purposes. Two modified versions of a prototype from Richard-Götze-Haus Tierärztliche Hochschule Hannover were used for the collections; their designs feature a hollow insert for an Artificial Vagina. The research highlights the phantom’s practicality for routine use based on criteria such as its attractiveness to stallions, robust construction, easy cleaning and disinfection, along with firm installation on a hygienic surface.

Method of Stallion Secretion Collection

• The researchers used a special device known as a phantom to collect genital secretions from stallions for research purposes. Three models of the phantom were used: the original and two slightly modified versions based on a design from the Richard-Götze-Haus Tierärztliche Hochschule Hannover.
• The phantoms were equipped with a flat hollow on their right side where an Artificial Vagina (AV) could be manually inserted. This design facilitated the collection process.

Practicability of the Phantoms

• The phantoms proved sufficiently sexually attractive to the stallions, facilitating successful collections of presecretions and semen. About 80-85% of the 1050 total collections of presecretions and approximately 70% of the 240 total semen collections were successful.
• The design and construction of the phantoms were solid and resistant, contributing to their practicality for routine application. The researchers did not report any significant wear and tear or damage during the collections, underlining the robustness of the phantoms.

Hygiene Considerations

• One of the critical features of the phantoms was their easy cleaning and disinfection. After each collection, the phantoms were thoroughly cleaned and disinfected to ensure the collection of representative samples uncontaminated by previous samples or bacteria.
• The phantoms were mounted on a hygienic floor, contributing to the overall cleanliness and hygiene of the collection process. This setup prevented any materials from the floor contaminating the samples.
