Which method is preferred for semen collection from a stallion?

1. Electroejaculator

2. Artificial vagina

3. Ampulla massage

4. Manual stimulation

The correct answer is: Artificial vagina

The preferred method for semen collection from a stallion is the use of an artificial vagina. This technique mimics the natural breeding process, providing the stallion with a more familiar and comfortable environment for ejaculation. The artificial vagina allows for the collection of high-quality semen while also minimizing stress for the animal. Using an artificial vagina has several advantages. It enables the collection of greater volumes of semen with a more concentrated sperm count, which is important for various reproductive technologies, such as artificial insemination. The thermal regulation provided by the artificial vagina also helps to maintain the optimal temperature for sperm viability during collection. While other methods such as electroejaculation, ampulla massage, and manual stimulation can be used to collect semen, they are generally less preferred due to factors like potential stress on the animal, lower semen quality, and lower volumes. The artificial vagina is widely accepted in both commercial and veterinary settings as the best practice for semen collection from stallions.
