Effect of ejaculation intervals on semen quality in cats

Area of Science:

• Veterinary Science
• Reproductive Biology
• Animal Reproduction

Background:

• Understanding optimal ejaculation intervals is crucial for feline breeding programs.
• Previous research on feline semen quality and collection frequency is limited.
• Male cat reproductive health impacts breeding success and conservation efforts.

Purpose of the Study:

• To investigate the impact of varying ejaculation intervals on male cat semen quality.
• To determine the relationship between collection frequency and sperm parameters.
• To provide data for optimizing semen collection protocols in domestic cats.

Main Methods:

• Semen was collected from 4 male cats (3-5 years old) using artificial vagina.
• Collections were performed 10 times at daily, every-other-day, and every-three-day intervals.
• Semen quality parameters, including sperm count, motility, and abnormality, were analyzed.

Main Results:

• Daily collections led to decreased sperm count and increased immature sperm after day 4.
• Semen volume varied between animals but was stable per individual across collections.
• Sperm count was higher in the first collection compared to the second (p<0.01) for less frequent intervals.
• Sperm motility and abnormality remained stable regardless of ejaculation interval or collection number.

Conclusions:

• Frequent daily ejaculation negatively impacts feline sperm quality.
• Less frequent ejaculation intervals (every other day or every three days) are more suitable for maintaining semen quality.
• These findings can inform best practices for semen collection in domestic cats for breeding and research.
