In this study, the effect of ejaculate sampling frequency on the morphological properties of sperm in Plymouth Rock roosters was determined. Four experimental groups were tested: of five, four, three, and two weekly ejaculates. The age of the roosters at the beginning of the experiment was 28 weeks and the duration of the experiment was 30 weeks. Increasing the frequency of semen sampling from one weekly sampling to five samplings per week had the following effects: 1. increase in ejaculate volume, but decrease in sperm density; 2. no significant changes in sperm motility; 3. increase of spermatozoa viability and 3. significant influences on the percentage of anomalies but no significant influences on the types of anomalies (the most common being the sperm head abnormalities).
